Check CAN Communication Line
1. IG "OFF"
2. Disconnect ECM/ECS ECU/HECU/EPB ECU/Cluster ECU connector and LDWS ECU connector.
3. Measure resistance between CAN-High terminal of ECM/ECS ECU/HECU/EPB ECU/Cluster ECU harness connector and CAN-High terminal of LDWS ECU harness connector.
4. Measure resistance between CAN-Low terminal of ECM/ECS ECU/HECU/EPB ECU/Cluster ECU harness connector and CAN-Low terminal of LDWS ECU harness connector.
  Specification: Below approx. 1Ω
5. Is the measured value within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
