Power Seat Slide Position Sensor Troubleshooting
- Raise the driver's power seat up with the power seat up-down switch, then remove the power seat (see FRONT SEAT REMOVAL/INSTALLATION
).NOTE: Be careful no to scratch the interior trim.
- Disconnect the power seat control unit connectors (see DRIVER'S POWER SEAT CONTROL UNIT INPUT TEST ).
- Disconnect the 4P connector from the slide position sensor.
- Check for continuity between the No. 2 terminal of the slide position sensor and A11 terminal of the power seat control unit.Fig 1: Checking Continuity Between No. 2 Terminal Of Slide Position Sensor And A11 Terminal Of Power Seat Control Unit

Is there continuity?
- YES - Go to step 5.
- NO - Repair open in the WHT/BLK wire.
- Check for continuity between the No. 3 terminal of the slide position sensor and A2 terminal of the power seat control unit.Fig 2: Checking Continuity Between No. 3 Terminal Of Slide Position Sensor And A2 Terminal Of Power Seat Control Unit

Is there continuity?
- YES - Go to step 6.
- NO - Repair open in the BLU/BLK wire.
- Reconnect all connectors to run the seat motors.
- Turn the ignition switch ON (II).

Is there about 5 V?
- YES - Go to step 9.
- NO - Repair open or short in the BRN wire.
- Check for voltage pulse between the No. 3 terminal of the slide position sensor and body ground when the slide switch moves forward or backward.

Does voltage pulse from 0 to about 5 V alternately?
- YES - Check for poor connections or loose terminals between the sensor and the driver's power seat control unit. If OK, replace the power seat control unit.
- NO - Check for a short in the wire. If the wire is OK, the slide position sensor is faulty; replace the slide motor assembly.
