Test H: Driver Seat Horizontal Adjustment Inoperative

  1. Check Seat Operation  - Operate driver seat control switch in all directions. If any direction operates, go to next step. If no directions operate, go to TEST J  .
  2. Test PID SFWD_SW  - Connect NGS tester to data link connector. Access driver seat module PID SFWD_SW. Operate seat forward then seat rearward switch while observing NGS display. If NGS display does not change from FWD to RWD as switch is operated, go to next step. If NGS display changes from FWD to RWD as switch is operated, go to step 9).
  3. Test Yellow/White Wire For Voltage  - Disconnect driver seat module connector C350. See Figure . Check voltage at Yellow/White wire of driver seat module harness connector C350. Press driver seat control switch seat rearward while observing voltmeter. If battery voltage does not exist, go to next step. If battery voltage exists, go to step 6).
  4. Test Yellow/White Wire For Open  - Disconnect driver seat control switch connector. See Figure . Check resistance in Yellow/White wire between driver seat module harness connector C350 and driver seat control switch harness connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Yellow/White wire.
  5. Test Yellow/White Wire For Short  - Check resistance in Yellow/White wire between driver seat module harness connector C350 and ground. If resistance is greater than 10,000 ohms, replace driver seat control switch. If resistance is 10,000 ohms or less, repair short in Yellow/White wire.
  6. Test Red/White Wire For Voltage  - Check voltage at Red/White wire of driver seat module harness connector C350. See Figure . Press driver seat control switch seat forward while observing voltmeter. If battery voltage does not exist, go to next step. If battery voltage exists, replace driver seat module.
  7. Test Red/White Wire For Open  - Disconnect driver seat control switch connector. Check resistance in Red/White wire between driver seat module harness connector C350 and driver seat control switch harness connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Red/White wire.
  8. Test Red/White Wire For Short  - Check resistance in Red/White wire between driver seat module harness connector C350 and ground. If resistance is greater than 10,000 ohms, replace driver seat control switch. If resistance is 10,000 ohms or less, repair short in Red/White wire.
  9. Test Motor  - Disconnect driver seat motor connector C351. See Figure . Check voltage between Red/White and Yellow/White wires of driver seat motor connector, while pressing driver seat control switch seat forward. If battery voltage does not exist, go to next step. If battery voltage exists, replace driver seat track assembly.
  10. Test Red/White Wire For Open  - Disconnect driver seat module connector C355. See Figure . Check resistance in Red/White wire between driver seat module harness connector C355 and driver seat motor harness connector C351. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Red/White wire.
  11. Test Yellow/White Wire For Open  - Check resistance in Yellow/White wire between driver seat module harness connector C355 and driver seat motor harness connector C351. If resistance is 5 ohms or less, replace driver seat module. If resistance is greater than 5 ohms, repair open in Yellow/White wire.
