Test W: Passenger Seat AUTOGLIDE Does Not Work Properly

NOTE: Connector C329 is a 3-terminal connector. Identify connector by wire color. See WIRING DIAGRAMS  .
  1. Test Seat Operation  - Operate passenger seat in all directions. If passenger seat operates smoothly and completely in all directions, go to next step. If seat does not operate smoothly and completely in all directions, repair passenger seat. See SYMPTOM CHART  under SYSTEM TESTING.
  2. Test PID AGLIDEF  - Connect NGS tester to data link connector. Access passenger seat module PID AGLIDEF. Move passenger seat back forward and rearward, while observing NGS tester display. If NGS tester does not display ACTIVE, go to next step. If NGS tester displays ACTIVE, go to step 5).
  3. Test Black/Light Green Wire For Open  - Disconnect passenger seat back switch harness connector C329. Measure resistance between ground and terminal No. 2 (Black/Light Green wire) at passenger seat back switch harness connector C329. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black/Light Green wire.
  4. Test Dark Green/Orange Wire For Open  - Disconnect passenger seat module harness connector C336. Measure resistance in Dark Green/Orange wire between terminal No. 4 at passenger seat module harness connector C336 and terminal No. 1 at passenger seat back switch harness connector C329. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Dark Green/Orange wire.
  5. Test PID AGLIDER  - Connect passenger seat module and passenger seat control switch harness connectors. Access passenger seat module PID AGLIDER. Move passenger seat back rearward, while observing NGS tester display. If NGS tester display did not read ACTIVE, go to next step. If NGS tester display read ACTIVE, replace passenger seat module.
  6. Test Black/Light Green Wire For Open  - Disconnect passenger seat back switch harness connector C329. Measure resistance between ground and terminal No. 2 (Black/Light Green wire) at passenger seat back switch harness connector C329. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black/Light Green wire.
  7. Test Dark Blue/Yellow Wire For Open  - Disconnect passenger seat module harness connector C336. Measure resistance in Dark Blue/Yellow wire between terminal No. 5 at passenger seat module harness connector C350 and terminal No. 3 at passenger seat back switch harness connector. If resistance is 5 ohms or less, passenger seat back switch. If resistance is greater than 5 ohms, repair open in Dark Blue/Yellow wire.
