Diagnosis Procedure
INFOID:0000000003767691
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 B11
-
Harness connector M77
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 B11 and M77.
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 driver seat control unit and the harness connector B11.
3.
CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
Check the continuity between the harness connector and the data link connector.
Is the inspection result normal?
YES (Present error)>>Check CAN system type decision again.
YES (Past error)>>Error was detected in the main line between the driver seat control unit and the data link
connector.
NO
>> Repair the main line between the harness connector M77 and the data link connector.
