INSPECTION PROCEDURE
| 1.CHECK HARNESS AND CONNECTOR (STEERING LOCK ACTUATOR ASSEMBLY - BODY GROUND) |
Disconnect the J29 connector from the steering lock actuator assembly.
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
Tester connection
(Symbols) | Condition | Specified condition |
| J29-1 (GND) - Body ground | Always | Below 1 Ω |
| J29-2 (SGND) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
