DIAGNOSIS BY SYMPTOM





Perform troubleshooting of the circuits for the applicable problem symptom in the order given in the chart above.

The Driver's Seat ECU communicates with the tilt & telescopic ECU about memory and return, so there are occasions when a power seat problem symptom is caused by trouble in the tilt and telescopic circuit. When the instruction "See tilt and telescopic section "appears in the matrix chart, proceed to the matrix chart in the tilt and telescopic section and inspect the circuits as directed by the matrix chart.

HINT:
- If the instruction "Proceed to next circuit inspection shown on matrix chart" is given in the flow chart for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
- If the trouble still reappears even though there are no abnormalities in any of the other circuit, then check and replace the driver's seat ECU as the last step.
