Note
The following inspection procedures for the parking assist monitor system are based on the assumption that the audio and visual system is normal. If the audio and visual system has any malfunctions, first proceed with troubleshooting the audio and visual system.
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.
Tech Tips
Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
