Main Line Between Laser and ICC Circuit

MAIN LINE BETWEEN LASER AND ICC 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 (connector side and harness side).
- Harness connector E34
- Harness connector B40
Is the inspection result normal?
YES - GO TO 2.
NO - Repair the terminal and connector.
2.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the following harness connectors.
- ICC sensor
- Harness connectors E34 and B40
2. Check the continuity between the ICC sensor harness connector and the harness connector.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair the main line between the ICC sensor and the harness connector E34.
3.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of ICC unit.
2. Check the continuity between the harness connector and the ICC unit harness connector.





Is the inspection result normal?
YES (Present error)-Check the following items again.
- Decision of CAN system type.
- Not received CONSULT-III data [SELF-DIAG RESULTS, CAN DIAG SUPPORT MNTR ("ECU list" included)].
- Procedure for detecting root cause.
YES (Past error)-Error was detected in the main line between the ICC sensor and the ICC unit.
NO - Repair the main line between the harness connector B40 and the ICC unit.
