Galant L4-2.4L (4G69) (2004)
3. Disconnect the negative battery terminal.
4. Measure the resistance between joint connector (3) terminals 6 and 17.
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 15.
NO: If the resistance measures less than 1 kOhm, repair the wiring harness between joint connector (3) and the A/C-ECU connector.
STEP 15. Check the A/C-ECU for short circuit. Measure the resistance at A/C-ECU connector C-15.
CAUTION: A digital multimeter should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
1. Disconnect A/C-ECU connector C-15, and measure the resistance at the component side of A/C-ECU connector C-15.
2. Measure the resistance between A/C-ECU connector terminals 14 and 15.
OK: 1 kOhm or more
Q: Does the resistance measure 1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, diagnose CAN bus lines thoroughly. Refer to "Diagnostic Item 16".
