6E-216 Engine Control System (4JH1)
DTC P1605 (Symptom Code C, D, E) (Flash Code 55)
Circuit Description
This diagnostic applies to internal microprocesso
r
integrity conditions within the engine control module
(ECM). The electronically erasable programmable read
only memory (EEPROM) memorize some data fo
r
engine control and communication with other control
module. If the ECM detects memory area malfunction
inside of the ECM, this DTC will set.
Condition for Setting the DTC
• The ECM detects internal seed or key file in
EEPROM data is destroyed (Symptom Code C).
• The ECM detects reading or writing from the
EEPROM data is failed during initialization
(Symptom Code D).
• The ECM detects total sum of EEPROM data is
not equal to registered value during initialization
(Symptom Code E).
Action Taken When the DTC Sets
• The ECM illuminates the malfunction indicato
r
lamp (MIL) when the diagnostic runs and fails.
• The ECM uses default EPROM data substitution o
f
faulty EEPROM. (Symptom Code D & E).
Condition for Clearing the MIL/DTC • The ECM turns OFF the MIL when the diagnostic
runs and does not fail.
• A history DTC clears after 40 consecutive driving
cycles without a fault. Or clear with the scan tool.

Engine Control System (4JH1) 6E-255
Symptoms – Engine Controls
Symptoms – Engine Controls
Important Preliminary Inspections Before Starting
Perform Diagnostic System Check – Engine Controls
before using the symptom tables, and verify that all o
f
the following are true:
• The engine control module (ECM) and malfunction
indicator lamp (MIL) are operating correctly.
• There are no diagnostic trouble codes (DTCs)
stored, or a DTC exists but without the MIL.
• 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 extremel
y
important. The visual and physical inspection can lead
to correcting a problem without further inspections, and
can save valuable time. Ensure that:
• The ECM grounds are clean, tight, and in thei
r
proper location.
• The vacuum hoses are not split or kinked, and
properly connected. Inspect thoroughly for an
y
type of leak or restriction.
• The mass air flow (MAF) sensor is properl
y
installed. The arrows on the plastic portion of the
sensor must point toward the engine.
• The air intake ducts are not collapsed or damaged.
• There are no leaks at the MAF sensor, an
y
connections or intake manifold sealing surfaces.
• The engine 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 keyword 2000 serial data
circuit. If you cannot locate an intermittent condition, a
cellular phone communication signal may cause the
condition.
Important:
The problem may or may not turn ON the MIL 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 orde
r
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 scan tool include the
following:
• Trigger the Snapshot feature in order to capture
and store engine 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 fo
r
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 MIL with
no stored DTC:
• The ECM grounds are loose or dirty. Refer to
Engine Controls Schematics.
• The MIL circuit intermittently shorted to ground.
• Electrical system interference caused by a
malfunctioning relay, ECM driven solenoid, o
r
switch. The electrical component can cause a
sharp electrical surge. Normally, the problem will
occur when the malfunctioning component is
operating.
• There is an open diode across the A/C
compressor clutch or any other open diodes.

2. Turn ON the scan tool.

4. Input correct VIN reading from stamped VIN o
r

Select Lock ECU and lock the programmed VIN.
Service Programming System (SPS)
Description
The service programming system (SPS) allows a
technician to program a control module through the data
link connector (DLC). The information transfer circuit that
is used at the DLC is the same serial data circuit used be
the scan tool for retrieving diagnostic trouble codes
(DTCs), displaying data, clearing DTCs etc. This
procedure offers the ability to install software/calibrations
matched to a particular vehicle.
Most control modules have two types of memory. The
software/calibrations reside in the flash memory. The two
types of memory are listed below: • Electrically Erasable Programmable Read Onl
y
Memory (EEPROM).
This type of memory allows selected portions o
f
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM, such as:
- The vehicle identification number (VIN)
- The software/calibrations identification numbers
- The control module security information
• Flash Read Only Memory-Flash Memory
Flash memory has increased memory storage capacity. During programming, all information within
this type of memory is erased, and then replaced
with entirely new information.
Service Programming Methods
The two methods of programming an engine control
module (ECM) are listed below: • Remote Programming
• Pass Thru Programming
For information on programming an ECM using one o
f
the methods listed above, refer to Service Programming
System (SPS) (Remote Procedure) or Service
Programming System (SPS) (Pass-Thru Procedure).
Before Programming a Control Module
Important:
DO NOT program an existing ECM with the identical
software/calibration package. This procedure is not a
short cut to correct the driveability condition. This is an
ineffective repair. An ECM should only be programmed
when the following occurs: • W hen a service procedure instructs you to replace
the ECM. W hen the ECM from another vehicle is
installed, VIN must be changed. And change
vehicle information as necessary such as type o
f
transmission.
• An updated software/calibrations is released.
Ensure that the following conditions are met before
programming an ECM: • The scan tool PCMCIA card is programmed with
the latest software.
• The TIS 2000 is installed with the latest software.
• The hardware key is plugged into the compute
r
port.
• Vehicle system voltage:
- There are no charging system concerns. All charging system concerns must be repaired
before programming the ECM.
- The battery voltage is greater than 12 volts bu
t
less than 16 volts. The battery must be fully
charged before programming the ECM.
-
A battery charger is NOT connected to the
vehicles battery. Incorrect system voltage o
r
voltage fluctuations from a battery charger may
cause programming failure or ECM damage.
- Turn OFF or disable any system that may put a load on the vehicles battery. Turn OFF o
r
disable systems such as:
◊ Heating, ventilation, and air conditioning
(HVAC) systems
◊ Headlights
◊ Room lights
◊ Accessory equipment
• The ignition switch is in the proper position. The
scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position o
f
the ignition switch during the programming
procedure unless instructed to do so.
• All tool connections are secure:
- The RS-232 cable
- The connection at the DLC
- The voltage supply circuits
