HINT:
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.
The power tilt and power telescopic steering column system uses the CAN communication system, so check its diagnostic
system before proceeding to troubleshooting.
If the problem still occurs when there is no abnormality in the related circuits, check the multiplex tilt and telescopic ECU and
replace it if necessary.
