Galant L4-2.4L (4G69) (2004)
YES: If the voltage measures 4.0 V or less, go to Step 9.
NO: If the voltage measures more than 4.0 V, go to Step 8.
STEP 8. Check the CAN_H line (communication line only) between joint connector (3) and the combination meter 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 combination meter connector C-101, 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 4 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 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 joint connector (3) and the combination meter connector.
STEP 9. Check the CAN_H line (communication line including the ETACS-ECU) between joint connector (3) and the ETACS-ECU connector
