Galant L4-2.4L (4G69) (2004)
1. Disconnect powertrain control module connector B-19 and ABS-ECU connector A-02, and measure the resistance at the harness side of
powertrain control module connector B-19.
2. Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION: Disconnect the negative battery terminal. For details refer to Service Precautions/Vehicle Damage Warnings.
3. Disconnect the negative battery terminal.
4. Measure the resistance between powertrain control module connector terminal 17 and body ground.
OK: 1 kOhm or more
CAUTION: Strictly observe the specified wiring harness repair procedure. For details refer to Service Precautions/Vehicle Damage Warnings.
Q: Does the resistance measure 1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, go to Step 26.
NO: If the resistance measures less than 1 kOhm, repair the wiring harness between powertrain control module connector and ABS-ECU
connector.
STEP 26. Check the CAN_H line inside the ABS-ECU for short to ground. Measure the resistance at ABS-ECU connector A-02.
CAUTION: A digital multimeter should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
CAUTION: The test wiring harness should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
