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.
- Using a scan tool, retrieve the percentage of remaining engine oil. Record the
remaining engine oil life.
- Disconnect
the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Disconnect the intake air temperature (IAT) sensor.
- Loosen the clamp at the air cleaner assembly.
- Remove the push pin attachment from the outlet resonator/duct assembly
to support bracket.
- Loosen the clamp at the throttle body assembly.
- Disconnect the PCV fresh air hose at the cam cover.
- Remove the outlet resonator/duct assembly.
- Remove the J 1 and J 2 connectors at the ECM.
- Remove the 4 ECM attachment bolts.
Installation Procedure
- Install
the ECM.
Notice: Refer to Fastener Notice in the Preface section.
- Install the ECM bolts.
Tighten
Tighten the engine control module bolts to 8 N·m
(71 lb in).
- Connect the J 1 and J 2 ECM electrical connectors.
- Install the outlet resonator/duct assembly into position.
- Connect the PCV fresh air vent hose assembly.
- Tighten the clamp at the throttle body assembly.
- Position the outlet resonator/duct assembly up with the support bracket
and install the push-pin.
- Tighten the clamp at the air cleaner assembly.
- Connect the intake air temperature (IAT) sensor connector.
- Connect the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
Notice: If a new ECM is being installed, it must be reprogrammed with new software and
calibrations. Refer to Service Stall System (SSS) User Guide for reprogramming procedures.
The ECM may be damaged if the reprogramming process is interrupted. Make sure the
scan tool is connected securely to the DLC and the vehicle battery has sufficient
charge.
Important: Ensure the original ECM has the correct VIN
and vehicle options.
- Reprogram the ECM. Refer to
Service Programming System (SPS)
in Programming .
Important: The new ECM must learn the passlock password
from the BCM. When the ECM reprogram is completed, use the SSS to perform the ECM
Passlock Relearn Procedure.
- Perform the Passlock Relearn Procedure using the Service Stall System (SSS).
- Turn the ignition to OFF for 10 seconds.
Important: Following the ECM reprogramming, the ECM
will have to learn the crankshaft notch variation for misfire diagnostics.
- Perform the crankshaft relearn procedure. Refer to
Crankshaft Position System Variation Learn
.
- Verify no DTCs exist. If one exists, refer to the specific DTC diagnostic.
