Engine Control Module Replacement
Removal Procedure
|
Caution:
|
|
• |
Turn the ignition OFF when installing or
removing the control module connectors and disconnecting or
reconnecting the power to the control module (battery cable,
powertrain control module (PCM)/engine control module
(ECM)/transaxle control module (TCM) pigtail, control module fuse,
jumper cables, etc.) in order to prevent internal control module
damage. |
|
|
• |
Control module damage may result when the
metal case contacts battery voltage. DO NOT contact the control
module metal case with battery voltage when servicing a control
module, using battery booster cables, or when charging the vehicle
battery. |
|
|
• |
In order to prevent any possible
electrostatic discharge damage to the control module, do no touch
the connector pins or the soldered components on the circuit
board. |
|
|
• |
Remove any debris from around the control
module connector surfaces before servicing the control module.
Inspect the control module connector gaskets when diagnosing or
replacing the control module. Ensure that the gaskets are installed
correctly. The gaskets prevent contaminant intrusion into the
control module. |
|
|
• |
The replacement control module must be
programmed. |
|
Note: 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 percent. If the replacement module is not
programmed with the remaining engine oil life, the engine oil will
need to be changed at 5 000 km (3,000 mi) from the last engine oil
change.
2. |
Using a scan tool, retrieve
the percentage of remaining engine oil. Record the remaining engine
oil life. |
4. |
Disconnect the 2 wiring
harness plug (2) from the engine control module (3). |
5. |
Unclip the engine control
module bracket (4) from the battery tray. |
6. |
Remove the 4 nuts (1).
|
7. |
Remove the engine control
module (3) from the engine control module bracket (4). |
Installation Procedure
1. |
Install the engine control
module (3) to the engine control module bracket (4). |
2. |
Install the 4 nuts (1) and
tighten to 9 N·m (80 lb in) . |
3. |
Clip the engine control module
bracket (4) to the battery tray. |
4. |
Connect the 2 wiring harness
plug (2) to the engine control module (3). |
