Removal Procedure
Important: It is necessary to record the remaining engine
oil life. If the replacement module is not programed with the remaining engine oil
life, the engine oil life will default to 100%. If the replacement module is not programmed
with the remaining engine oil life, the engine oil will need to be changed at 5000 km
(3,000 mi) from the last engine oil change.
Important: It is necessary to record the remaining automatic
transmission fluid life. If the replacement module is not programed with the remaining
automatic transmission fluid life, the automatic transmission fluid life will default
to 100%. If the replacement module is not programmed with the remaining automatic
transmission fluid life, the automatic transmission fluid will need to be changed
at 83000 km (50,000 mi) from the last automatic transmission fluid change.
- Using a scan tool, retrieve the percentage of remaining engine oil and the remaining
automatic transmission fluid life. Record the remaining engine oil and the remaining
automatic transmission fluid life.
Important: The key must be in the LOCK position for
a minimum of 30 seconds prior to disconnecting power to the PCM. This allows the
PCM to store the vehicle information into the EEPROM. Failure to wait the 30 seconds
may result in a EEPROM reset and the fluid life indexes being reset to 0.
- Disconnect the negative battery cable.
- Remove the brace from between the LH fender and the radiator core support.
- Disconnect the MAF/IAT sensor electrical connector.
- Loosen the intake air duct clamp at the throttle body.
- Lift the air cleaner element assembly off of the air inlet assembly locating
pins.
- Slide the air cleaner element assembly toward the fender to separate
the air cleaner element assembly from the air inlet assembly.
- Remove the Intake Air duct/air cleaner assembly.
- Open the air inlet housing to gain access to the PCM.
- Loosen the connector attaching bolts.
- Disconnect both PCM connectors.
Installation Procedure
Important: The replacement PCM must be programmed (flashed
using the latest Techline equipment and procedures.
Important: Be sure to transfer the PCM isolators to
the replacement PCM.
- Slide the PCM Isolators on to the PCM.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the PCM connectors.
Tighten
Tighten the PCM connectors screws to 8 N·m
(71 lb in).
- Place the PCM into the air inlet housing.
- Close and latch the air inlet housing.
- Ensure that the locating pin grommets
are present and properly positioned in the bottom of the air cleaner assembly.
- Install the air inlet housing by inserting the outboard locating pin
into the inside fender alignment hole.
- Press the air inlet housing firmly down to engage the bottom locating
pins.
- Install the intake air duct/air cleaner assembly onto the air inlet
housing.
Important: An improperly installed air cleaner or a
distorted /missing Intake Air Duct may cause a DTC to set. Ensure that the following
areas are checked:
| • | The air cleaner assembly and Intake air duct is installed correctly and
that there are no kinks or folds in the duct |
| • | No debris in the air cleaner assembly or the MAF sensor inlet screen
that may distort the air flow. |
| • | No signs of damage to the air cleaner assembly or the intake air duct.
If a problem is found, replace as necessary. |
- Install the Intake Air duct to the throttle body.
Tighten
Tighten the intake air duct clamp to 3 N·m
(27 lb in).
- Install the brace between the LH fender and the radiator core support.
Tighten
Tighten the brace bolts to 24 N·m
(18 lb ft).
- Reconnect the MAF/IAT sensor connector.
- Connect the negative battery cable.
- Start the engine. If the engine fails to start verify the following:
| • | The PCM contains the correct program (DTC P0602 not set). |
| • | The PCM connectors are fully engaged into the PCM. |
| • | That all fuses are present and not blown. |
- Connect a scan tool and perform the following:
| • | Use the scan tool to reset the transaxle fluid lifre to that recorded
prior to PCM replacement. |
| • | Use the scan tool to reset the engine oil life to that recorded prior
to PCM replacement. |
