NO>>Check the harness and repair or replace the root cause.
CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
Check the continuity between the 8CH CAN gateway harness connector terminals.
| 8CH CAN gateway harness connector | Continuity | ||
| Connector No. | Terminal No. | ||
| M9 | 60 | 61 | Not existed |
Is the inspection result normal?
YES>>GO TO 5.
NO>>Check the harness and repair or replace the root cause.
CHECK HARNESS CONTINUITY (SHORT CIRCUIT)
Check the continuity between the 8CH CAN gateway and the ground.
| 8CH CAN gateway harness connector | Ground | Continuity | |
| Connector No. | Terminal No. | ||
| M9 | 60 | Not existed | |
| 61 | Not existed | ||
Is the inspection result normal?
YES>>GO TO 6.
NO>>Check the harness and repair or replace (if shield line is short) the root cause.
CHECK 8CH CAN GATEWAY AND CHASSIS CONTROL MODULE TERMINATION CIRCUIT
-
Remove the 8CH CAN gateway and the chassis control module.
-
Check the resistance between the 8CH CAN gateway terminals.
8CH CAN gateway Resistance (Ω) Terminal No. 60 61 Approx. 108 – 132 -
Check the resistance between the chassis control module terminals.
Chassis control module Resistance (Ω) Terminal No. 10 26 Approx. 108 – 132
Is the measurement value within the specification?
YES>>GO TO 7.
NO>>Replace the 8CH CAN gateway and/or the chassis control unit.

CHECK SYMPTOM
Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with customer)” are reproduced.
Inspection result
Reproduced>>GO TO 8.
Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is detected.
CHECK UNIT REPRODUCTION
Perform the reproduction test as per the following procedure for each unit.
-
Ignition switch OFF.
-
Disconnect the battery cable from the negative terminal.
-
Disconnect one of the unit connectors of chassis CAN communication 6 circuit.
NOTE:
8CH CAN gateway and chassis control module have a termination circuits. Check other units first.
-
Connect the battery cable to the negative terminal. Check if the symptoms described in the “Symptom (Results from interview with customer)” are reproduced.
NOTE:
Although unit-related error symptoms occur, do not confuse them with other symptoms.
Inspection result
Reproduced>>Connect the connector. Check other units as per the above procedure.
Non-reproduced>>Replace the unit whose connector was disconnected.
