3. Measure the voltage between joint connector (3) terminal 6 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 A/C-ECU connector.
STEP 15. Check the CAN_H line (communication line including the SRS-ECU) between joint connector (3) and the SRS-ECU connector for
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 3 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 21.
