6E-276 Engine Control System (4JH1)
1. Connect the scan tool to the vehicle DLC, with theengine and the scan tool OFF.
2. Turn ON the scan tool.
3. Select Diagnostic > appropriate vehicle identification > Powertrain > 4JH1-TC >
Programming > Program VIN.
4. Input correct VIN reading from stamped VIN o
r
affixed VIN plate on the vehicle.
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

Symptoms, and restart the
diagnosis
Drive Belt Squeal
Definition
Accessory drive belt squealing can be defined as a loud screeching noise caused by a slipping drive belt. Belt squeal is
unusual in multi-rib belts. Drive belt squeal generally occurs when a heavy load is applied to the drive belt, such as an
air-conditioning compressor engagement, snapping the throttle, seized pulley or a faulty accessory drive component.
Diagnostic Aids
If the noise is intermittent, confirm the accessory drive components by varying their loads, making sure they are operated
to their maximum capacity. An overcharged A/C system, restrictions in the power steering pressure circuit or a faulty
generator or coolant pump are likely causes of accessory drive belt squeal.
A loose or incorrectly installed body component, suspension component or other item may be the cause of the noise.
Test Description
The numbers below refer to steps in the diagnostic table.
2 The noise may not be engine related. This step is to confirm the engine is making the noise. If the engine is not making the noise, do not proceed further with this diagnostic procedure.
3 The noise may be an internal engine noise. Removing the drive belt and operating the engine briefly will confirm whether or not the noise is related to the drive belt.
CAUTION
When running the engine with the accessory
drive belt removed, the coolant pump will not
be operating and the engine may overheat if
left unsupervised even for a short period.
NOTE
There may also be a number of DTCs set when
running the engine with the accessory drive belt
removed.
4 Confirms an accessory drive component does not have a seized bearing. W ith the belt removed, test the bearings in the accessory drive components spin free and smooth.
5 Confirms the drive belt tensioner is operating correctly. If the drive belt tensioner is not operating correctly, drive belt tension will not be maintained, resulting in a belt squealing noise
6 Confirms the belt is not too long, which would prevent the tensioner from working as intended. Also, if an excessively long belt has been fitted, it may also be routed incorrectly and may be turning an accessory drive
component in the wrong direction.

7 Misalignment of the pulleys may be caused by one of the following:
• Incorrect mounting of an accessory drive component,
• Incorrect installation of an accessory drive pulley or,
• Bent or damaged pulley.
Test for a misaligned pulley using a straight edge in the pulley grooves across 2 or 3 pulleys. If a misaligned pulley is found, refer to the relevant component service information for the correct installation and removal procedures.

Drive Belt Whine
Definition
Accessory drive belt whine can be defined as a high-pitched continuous noise that is most likely to be caused by a failed
bearing in one of the accessory drive components.
Diagnostic Aids
The drive belts themselves will not cause a whine. If the noise is intermittent, confirm the accessory drive components by
varying their loads, making sure they are operated to their maximum capacity. An overcharged A/C system, restrictions
in the power steering pressure circuit or a faulty generator or coolant pump are likely causes of accessory drive belt
whine.

1.3 Battery Ratings
There are two battery ratings to consider when replacing a battery, reserve capacity (RC) and cold cranking amps (CCA).
Ensure the replacement battery meets or exceeds these rating specifications.
Reserve Capacity
The RC of a battery is the amount of time (measured in minutes) the vehicle will travel at night with minimum electrical
load and no generator input.
