INSPECTION PROCEDURE

NOTICE:

Since the parking assist monitor system has functions that use CAN communication system, first confirm that there is no malfunction in the communication system by inspecting the CAN communication functions in accordance with the "How to Proceed with Troubleshooting" procedures. Then, conduct the following inspection procedure.
When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point (LandCruiser RM0000035DE05TX.html).
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 (LandCruiser RM0000035DD06LX.html).
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
