Diagnosis Procedure

INFOID:0000000003841876

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the data link connector for damage, bend and loose connection
(connector side and harness side).
