| Trouble symptom | Trouble area | Inspection item |
|---|---|---|

| Harness of fuse | Blown fuse | |
| Remove the control unit connector and check the continuity in the solenoid harness (between terminal No.2 and No.3) | ||
| Control module | Turn the ignition key momentarily to ACC or LOCK | |
| Check for continuity in each harness and for abnormalities in the control module power circuit | ||
| While driving at medium or high speed, steering remains light | Control module | Use a tester to check the stationary steering effort |
| Check the solenoid current in relation to changes in vehicle speed | ||
| Steering gear and linkages | Solenoid by-pass valve operation |
