C1640 CAN Time-out Cluster - W/Harness Inspection
Terminal and Connector Inspection
1. Many malfunctions in the electrical system are caused by poor harness(es) and terminal condition.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
CAN Communication line Inspection
Check CAN communication line
1. IG "OFF"
2. Disconnect cluster ECU connector and ECS ECU connector.
3. Measure resistance between CAN-High terminal of cluster ECU harness connector and CAN-High terminal of ECS ECU harness connector.
4. Measure resistance between CAN-Low terminal of cluster ECU harness connector and CAN-Low terminal of ECS ECU harness connector.
Specification : Below approx. 1 Ohms
5. Is the measured value within specification?
