Galant V6-3.8L (6G75) (2005)
STEP 46. Check the CAN_L line (communication line only) between joint connector (3) and the intermediate connector for a short circuit.
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 intermediate connector C-22 and 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) terminals 14 and body ground.
OK: 1 kOhm or more
CAUTION: Strictly observe the specified wiring harness repair procedure. For details refer to Precautions on How to Repair The CAN Bus
Lines.
Q: Does the resistance measure 1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, diagnose CAN bus lines thoroughly by referring 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).
