Diagnosis Procedure
INFOID:0000000005146472
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 F14
-
Harness connector E5
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair the terminal and connector.
2.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the harness connectors F14 and E5.
2. Check the continuity between the harness connector terminals.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair the main line between the A/T assembly and the harness connector F14.
3.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Disconnect the connector of ICC sensor.
2. Check the continuity between the harness connector and the ICC sensor 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 A/T assembly and the ICC sensor.
NO
>> Repair the main line between the harness connector E5 and the ICC sensor.
