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 8 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 24.
NO: If the voltage measures more than 4.0 V, go to Step 22.
STEP 22. Check multi-center display unit (middle-grade type) connector C-05 for loose, corroded or damaged terminals, or terminals pushed
back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector. For details refer to Service Precautions/Vehicle

Part 2
STEP 23. Check the CAN_H line (communication line only) between joint connector (3) and multi-center display unit (middle-grade type)
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.
