Galant L4-2.4L (4G69) (2004)
YES: If the resistance measures 1 kOhm or more, diagnose CAN bus lines thoroughly. Refer to "Diagnostic Item 16".
NO: If the resistance measures less than 1 kOhm, repair the wiring harness between intermediate connector C-22 and joint connector (3).
STEP 21. Check the CAN_H line (communication line including the multi-center display unit (middle-grade type)) between joint connector (3)
and middle-grade multi-center display connector for short to ground. Measure the resistance at joint connector (3) C-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.
1. Disconnect joint connector (3) C-02, and measure the resistance at the wiring harness side of joint connector (3) C-02.
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 joint connector (3) terminal 8 and body ground.
OK: 1 kOhm or more
Q: Does the resistance measure 1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, go to Step 24.
NO: If the resistance measures less than 1 kOhm, go to Step 22.
