Checks Actions
Temperature Related The Tech 2 Freeze Frame / Failure Records or Snapshot data may be used if applicable
to the fault condition. Refer to 4.1 Diagnostic General Descriptions for information on
Tech 2 ECU diagnostic tests.
• If the intermittent fault is heat related, review the Tech 2 data in relationship to the
following:
• high ambient temperature,
• underhood / engine generated heat,
• circuit generated heat due to a poor electrical connection or high electrical
load, and
• higher than normal load conditions (towing, etc.).
• If the intermittent fault is related to cold ambient or engine temperature, review the
Tech 2 data in relationship to the following:
• low ambient temperature, and
• the fault condition that occurs only on a cold start situation.
Additional Tests
• Check for incorrect installation of aftermarket electrical equipment such as the
following:
• mobile phones,
• theft deterrent alarms,
• lights, or
• radio equipment.
• Check for electromagnetic Interference (EMI) caused by a faulty relay, ECM
controlled solenoid or switch. The fault is triggered when the relay or solenoid is
activated.
• Check the A/C compressor clutch and some relays that contain a clamping diode
or resistor for an open circuit.
• Check the generator for a faulty rectifier bridge that may allow A/C noise into the
PIM electrical circuit.
When all diagnosis and repairs are completed, check the engine management system for correct operation.

7 Ensure that all wiring harness connectors are fitted correctly and secure.
8 W hen steam or pressure cleaning vehicle components, such as engines, transmissions, etc., do not direct the cleaning nozzle at any system electrical wiring harness connectors or components.
9 Do not clear any DTCs unless instructed.
10 The fault must be present when using the Diagnostic Trouble Code (DTC) Diagnostic Tables. Otherwise, misdiagnosis or replacement of good parts may occur.
11 Do not touch any electronic control module connector pins or soldered components on the circuit board. This is required to avoid the possibility of electrostatic discharge damage.
12 Use only the test equipment specified in the diagnostic tables, as other test equipment may give incorrect results or damage good components.
13 Electronic control modules are designed to withstand normal current draws associated with vehicle operation. However, the following fault conditions or incorrect test procedure may overload internal control module circuits and
irreparably damage the control module:
• A short to voltage fault condition in any of the control module low reference circuits may cause internal and/or
sensor damage. Therefore, any short to voltage fault condition in the control module low reference circuits
must be rectified before replacing a faulty component.
• A short to ground fault condition in any of the control module 5 volts reference circuits may cause internal
control module and/or sensor damage. Therefore, any short to ground fault condition in the control module 5
volt reference circuits must be rectified before replacing a faulty component.
• W hen using a test light to test an electrical circuit, do not use any of the control module low reference circuits
or 5 volts reference circuits as a reference point. Otherwise, excessive current draw from the test light may
damage the control module.
14 Disregard DTCs that set while performing the following diagnostic Steps:
• Using the Tech 2 output control function, or
• Disconnecting a control module system sensor connector then switching the ignition ON.
15 After completing the required diagnostics and service operations, road test the vehicle to ensure correct system operation.
4.4 Preliminary Checks
The Preliminary Checks is a set of visual and physical checks or inspections that may quickly identify a control module
system fault condition:
1 Refer to relevant Service Techlines for information regarding the fault condition.
2 Ensure that the battery is fully charged.
3 Inspect the battery connections for corrosion or a loose terminal.
4 Ensure that all relevant control module system related fuses are serviceable.
5 Inspect for incorrect aftermarket theft deterrent devices, lights or mobile phone installation.
6 Ensure that there is no speaker magnet positioned too close to any electronic module that contains relays.
7 Inspect the system wiring harness for proper connections, pinches or cuts.
8 Ensure that all control module related electrical wiring connectors are fitted correctly.
9 Inspect the control module ground connections for corrosion, loose terminal or incorrect position.
10 Ensure that the resistance between the control module housing and the battery ground cable is less than 0.5 ohms.
11 Check that the control module and its mounting bracket is secure.
12 Check all control module related components for correct installation.
13 Check the control module and related wiring harness routing to ensure that no rubbing or cutting of the wiring harness by sharp body components can occur.

Symptoms - Transmission Controls
Symptoms - Transmission Controls
Important Preliminary Inspections Before Starting
Perform Diagnostic System Check - Transmission
Controls before using the symptom tables, and verify
that all of the following are true:
• The TCM and check trans lamp is operating correctly.
• The scan tool data is within the normal operating range. Refer to Scan Tool Data List in this section.
• Verify the customer concern and locate the correct symptom in the table of contents. Inspect the items
indicated under that symptom.
Visual and Physical Inspection
Several of the symptom procedures ask for careful
visual and physical inspection. This step is extremely
important. The visual and physical inspection can lead
to correcting a problem without further inspections, and
can save valuable time. Ensure that:
• The TCM grounds are clean, tight, and in their proper location.
• The transmission harness wiring and terminals are properly connected and are not pinched or cut.
Intermittent
Important: Inspect for improper installation of electrical
components if an intermittent condition exists. Inspect
for aftermarket add-on electrical equipment devices,
lights, and cellular phones. Verify that no aftermarket
equipment is connected to the serial data circuit.
Important: The problem may or may not turn ON the
check trans lamp or store a DTC. Faulty electrical
connections or wiring cause most intermittent
problems.
Perform a careful visual and physical inspection of the
suspect connectors for the following conditions:
• Improperly mated connector halves
• Terminals that are not seated
• Terminals that are damaged or improperly formed
Reform or replace connector terminals in the problem
circuit in order to ensure proper contact tension.
Remove the terminal from the connector body in order
to inspect for poor terminal wire connection.
Road test the vehicle with the DMM connected to the
suspected circuit. An abnormal reading that occurs
when the malfunction occurs is a good indication that
there is a malfunction in the circuit being monitored.
Use the scan tool in order to help detect intermittent
conditions. Useful features of the Tech 2 includes the
following: • Trigger the Snapshot feature in order to capture
and store transmission parameters when the
malfunction occurs. Review this stored information
in order to see the specific running conditions that
caused the malfunction.
• Use the Plot Function on the scan tool in order to plot selected data parameters. Review this stored
information to aid in locating an intermittent
problem. Refer to the scan tool Users Guide for
more information.
Important: If the intermittent condition exists as a start
and then stall, test for DTCs relating to the vehicle theft
deterrent system. Test for improper installation of
electrical options such as lights, cellular phones, etc.
Any of the following may cause an intermittent check
trans lamp with no stored DTC:
• The TCM grounds are loose or dirty. Refer to Transmission Controls Schematics.
• The check trans lamp circuit intermittently shorted to ground
• Electrical system interference caused by a malfunctioning relay, TCM driven solenoid, or
switch. The electrical component can cause a
sharp electrical surge. Normally, the problem will
occur when the malfunctioning component is
operating.
• There are any open diodes.
Important: The following symptom tables contain
groups of possible causes for each symptom. The
order of these procedures is not important. If the scan
tool readings do not indicate the problems, then
proceed in a logical order, easiest to check or most
likely to cause first. In order to determine if a specific
vehicle is using a particular system or component, refer
to Transmission Controls Schematics for an
application.
Use the following tables when diagnosing a symptom
complaint:
• Intermittent Conditions
• Vehicle Does Not Run
• Trouble at Starting
• Faulty Gearshift
• Faulty Shift Pattern
• No or Error Gearshift
• Faulty Operation During Running
• Faulty Operation in Stopping
• Faulty Lock Up
• No Lock Up
• Transmission Fluid Leak
•Others

7A2-94 TRANSMISSION CONTROL SYSTEM (JR405E)
Temperature Sensitivity• An intermittent condition may occur when a component/ connection reaches
normal operating temperature. The condition may occur only when the
component/ connection is cold, or only when the component/ connection is hot.
• If the intermittent is related to heat, review the data for a relationship with the following:
- High ambient temperatures.
- Underhood/ engine generated heat.
- Circuit generated heat due to a poor connection, or high electrical load.
- Higher than normal load conditions, towing, etc.
• If the intermittent is related to cold, review the data for the following: - Low ambient temperatures-In extremely low temperatures, ice may form in a connection or component. Test for water intrusion.
- The condition only occurs on a cold start.
- The condition goes away when the vehicle warms up.
• Information from the customer may help to determine if the trouble follows a pattern that is temperature related.
Electromagnetic Interference (EMI) and
Electrical Noise Some electrical components/ circuits are sensitive to EMI or other types of electrical
noise. Inspect the following conditions:
• A misrouted harness that is too close to high voltage/ high current devices such as injection components, motors, generator etc. These components may
induce electrical noise on a circuit that could interfere with normal circuit
operation.
• Electrical system interference caused by a malfunctioning relay, or the TCM driven solenoid or switch. These conditions can cause a sharp electrical surge.
Normally, the problem will occur when the malfunctioning component is
operating.
• Improper installation of non-factory or aftermarket add on accessories such as lights, 2-way radios, amplifiers, electric motors, remote starters, alarm systems,
cell phones, etc. These accessories may lead to an emission related failure
while in use, but do not fail when the accessories are not in use.
• Test for any open diodes. Some relays may contain a clamping diode.
• Test the generator for a bad rectifier bridge that may be allowing AC noise into the electrical system.
Incorrect TCM Programming • There are only a few situations where reprogramming a TCM is appropriate:
- An ECM from another vehicle is installed.
- Revised software/ calibration files have been released for this vehicle.
Important: DO NOT reprogram the TCM with the SAME software/ calibration files
that are already present in the TCM. This is not an effective repair for any type of
driveability problem.
• Verify that the TCM contains the correct software/ calibration. If incorrect programming is found, reprogram the TCM with the most current software/
calibration.
Duplicating Failure Conditions • If none of the previous tests are successful, attempt to duplicate and/ or capture
the failure conditions.
• An alternate method is to drive the vehicle with the DMM connected to a suspected circuit. An abnormal reading on the DMM when the problem occurs,
may help you locate the problem.
Scan Tool Snapshot The scan tool can be set up to take a Snapshot of the parameters available via serial
data. The Snapshot function records live data over a period of time. The recorded
data can be played back and analyzed. The scan tool can also graph parameters
singly or in combinations of parameters for comparison. The Snapshot can be
triggered manually at the time the symptom is noticed, or set up in advance to trigger
when a DTC sets.
An abnormal value captured in the recorded data may point to a system or
component that needs to be investigated further.
Refer to the scan tool Users Guide for more information.

Resetting and Programming
Resetting and Programming Guidelines
Notice:The security information must be programmed
when the ICU, ECM, PIM or transponder key(s) is
replaced, or transponder key(s) is added.
Vehicle Security Information Card (If issued)
When performing ICU, ECM, PIM or transponder key(s)
resetting or programming functions using a scan tool,
you will be prompted to enter four digits of security
code (1). This information is found on the vehicle
security information card issued with the vehicle when
new. If the card is unavailable, contact a distributor’s
service department to obtain the relevant security code.
For new owners, distributor or dealership must provide
vehicle security information card that has identification
numbers of owner’s vehicle immobilizer system. This
information is very important in case of repair or
transponder key is lost. It is necessary to provide
following items in your responsibility.
• Vehicle security information card to a new owner.
• Blank vehicle security information card it is for reissue.
• Instruction to your dealership how to use it.
Your organization must keep security code for all
vehicles as confidential data. In case of vehicle security
information card is lost, the data can be requested from
a distributor’s service department. This request will only
be processed if accompanied by the enclosed form and
proof of ownership. Once the data is received, it can be
entered in a blank card and given to the customer. The
unused card should be destroyed. Instructions on filling
out the Data Request Vehicle Security Information Card
as follows.
• The data requested under items 1 to 10 must be provided completely, including the authorized
dealership number, the vehicle identification
number (VIN) and engine type/ number. • Complete the form by entering data and signature/
authorized dealership stamp and send it along with
proof of ownership to address provided in the form.
• The requested data will be sent by fax to dealership that made the request after your
organization has confirmed that the information is
correct.
Security Code
The security code is required when performing ICU,
ECM, PIM or transponder key(s) resetting or
programming functions. When a scan tool requests the
security code to be entered, and an incorrect code is
entered, the ICU, ECM or PIM will go into a security
wait time stage. This wait time stage will prevent any
further attempts to enter the security code until the wait
time has elapsed. Should a second incorrect security
code be entered after the initial wait time has elapsed,
the ICU, ECM or PIM will go into a second wait time
stage. The wait time will increase each time an
incorrect code is entered. When the correct code is
entered the wait time will rest back to its original value
of 10 seconds.
• Stage 1 = 10 seconds
• Stage 2 = 10 seconds
• Stage 3 = 10 minutes
• Stage 4 = 20 minutes
• Stage 5 = 40 minutes
