STEERING COLUMN: POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM: PROBLEM SYMPTOMS TABLE (2008 Sequoia)

PROBLEM SYMPTOMS TABLE

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.
