STEP 2. Check the wiring harness between joint connector (CAN1) C-103 and CAN box unit connector C-13.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN1) C-103 and CAN box unit connector C-301, and check the wiring harness.
2. Check the wiring harness between joint connector (CAN1) C-103 (terminal No.10) and CAN box unit connector C-13 (terminal No.8)
3. Check the wiring harness between joint connector (CAN1) C-103 (terminal No.23) and CAN box unit connector C-13 (terminal No.9)
Q: Is the wiring harness between joint connector (CAN1) C-103 and CAN box unit connector C-13 in good condition?
YES : Check the power supply circuit of the CAN box unit. Refer to Chassis electrical MMCS -Diagnosis. See: Accessories and Optional
Equipment/Testing and Inspection/Symptom Related Diagnostic Procedures/Trouble Symptom Chart
