Diagnosis Procedure
1.CONNECTOR INSPECTION
  1. Turn the ignition switch OFF.
  2. Disconnect the battery cable from the negative terminal.
  3. Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
    • Data link connector
    • 8CH CAN gateway
Is the inspection result normal?
.
Repair the terminal and connector.
 
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
  1. Disconnect the connector of 8CH CAN gateway.
  2. Check the continuity between the 8CH CAN gateway harness connector terminals.

Is the measurement value within the specification?
(Present error)Check CAN system type decision again.
(Past error)Error was detected in the diagnostic CAN communication circuit.
Replace the 8CH CAN gateway.
