Galant V6-3.8L (6G75) (2005)
STEP 25. Check the CAN_H line (communication line only) between intermediate connector C-29 and joint connector (3) for a short to the
power supply. Measure the voltage 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-29 and joint connector (3) C-02, and measure the voltage at the wiring harness side of joint connector (3)
C-02.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between joint connector (3) terminal 9 and body ground.
OK: 1.0 V or less
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 voltage measure 1.0 V or less?
YES: If the voltage measures 1.0 V or less, diagnose CAN bus lines thoroughly by referring to DIAGNOSTIC ITEM 16.
NO: If the voltage measures more than 1.0 V, repair the wiring harness between intermediate connector C-29 and joint connector (3).
