INSPECTION PROCEDURE
- NOTICE:
- When "System initializing" is displayed on the multi-display after disconnecting the cable from the negative (-) battery terminal, correct the steering angle neutral point (Click here).
- Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the parking assist monitor system may be needed (Click here).
| 1.CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY) |
Disconnect the S31 rear television camera assembly connector.
Disconnect the F77 multi-display assembly connector.
Measure the resistance according to the value(s) in the table below.
