C1628 CAN Timeout - Cluster - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
3. Has a problem been found ?






CAN communcation line inspection

1. Connect HCU, PCM, MCU, BMS, A A F, FATC connector
2. IG KEY "ON"
3. Measure voltage between CAN high terminal(# 3) of diagnostic connector and chassis ground.
4. Measure voltage between CAN low terminal(#11) of diagnostic connector and chassis ground.




5. Is the measured resistance within specifications?






CAN Circuit Inspection (EPS <--> CLU)

1. Ignition "On"
2. Disconnect EPS CM and CLU(PCM).
3. Measure resistnace between CAN High of ESP CM and CLU.
4. Measure resistnace between CAN Low of ESP CM and CLU.




5. Is the measured value within specification ?
