HINT:
- Use the table below to help determine the cause of the problem symptom. 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 multiplex communication system, so check its diagnostic system before proceeding to troubleshooting.
- If the instruction "PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE" is given in the flowchart , proceed to the circuit with the next highest number in the table below to continue the check.
- If the problem still occurs when there is no abnormality in the related circuits, check the multiplex tilt and telescopic ECU and replace if necessary.
