Galant L4-2.4L (4G69) (2004)
3. Measure the voltage between joint connector (3) terminal 14 and body ground.
OK: 1.0 V or less
CAUTION: Strictly observe the specified wiring harness repair procedure. For details refer to Service Precautions/Vehicle Damage Warnings.
Q: Does the voltage measure 1.0 V or more?
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-22 and joint connector (3).
STEP 47. Check the CAN_L line (communication line including the multi-center display unit (middle-grade type)) between joint connector (3)
and middle-grade multi-center display connector 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 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 19 and body ground.
OK: 4.0 V or less
Q: Does the voltage measure 4.0 V or less?
YES: If the voltage measures 4.0 V or less, go to Step 50.
