CAN

ICC BRANCH LINE CIRCUIT


Diagnosis Procedure

1.CHECK CONNECTOR
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).
- ICC sensor integrated unit
- CAN gateway (AWD models with active AFS and ICC system)
Is the inspection result normal?
YES (AWD models with active AFS and ICC system)-GO TO 2.
YES (Except for AWD models with active AFS and ICC system)-GO TO 3.
NO - Repair the terminal and connector.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of CAN gateway.
2. Check the continuity between the CAN gateway harness connector terminals.





Is the inspection result normal?
YES - GO TO 3.
NO - Check the harness and repair the root cause (CAN communication circuit 2).
3.CHECK HARNESS FOR OPEN CIRCUIT
1. Connect the connector of CAN gateway. (AWD models with active AFS and ICC system)
2. Disconnect the connector of ICC sensor integrated unit.
3. Check the resistance between the ICC sensor integrated unit harness connector terminals.





Is the measurement value within the specification?
YES - GO TO 4.
NO - Repair the ICC sensor integrated unit branch line.
4.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ICC sensor integrated unit. Refer to the following.
- Models with ICC (Full speed range): ICC (Full Speed Range)
- Models with DCA: DCA
Is the inspection result normal?
YES (Present error)-Replace the ICC sensor integrated unit. Refer to the following.
- Models with ICC (Full speed range): ICC (Full Speed Range)
- Models with DCA: Exploded View
YES (Past error)-Error was detected in the ICC sensor integrated unit branch line.
NO - Repair the power supply and the ground circuit.
