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 ETACS-ECU connector C-218, 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 5 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 14.
NO: If the voltage measures more than 1.0 V, repair the wiring harness between joint connector (3) and the ETACS-ECU connector.
STEP 12. Check the CAN_H line (communication line including the A/C-ECU) between joint connector (3) and the A/C-ECU connector for a
short to the power supply. Measure the voltage at joint connector (3) C-02.
