If NGS tester indicates switch is active, check Black/Orange wire for short to battery voltage. Also check for stuck switch. Repair or replace as necessary. Retest system.
  7. OFF Switch Test  - Repeat procedure in step 5). Press OFF switch. If NGS does not indicate OFF switch active, check for open in Brown/Orange wire. Also check for damaged switch. Repair or replace as necessary. Retest system.
  8. "1" Switch Test  - Repeat procedure in step 4). Press "1" switch. If NGS indicates OFF switch active, go to next step. If NGS does not indicate OFF switch active, check for open in Brown/Light Green wire. Also check for damaged switch. Repair or replace as necessary. Retest system.
  9. "2" Switch Test  - Repeat procedure in step 6). Press "2" switch. If NGS indicates OFF switch active, go to next step. If NGS does not indicate OFF switch active, check for open in Black/Orange wire. Also check for damaged switch. Repair or replace as necessary. Retest system.
  10. Seat & Mirror MEMORY "1" Test  - Turn ignition on. Set gear selector in Park. Press "1" switch. Seat and mirrors may move. Move seat and mirrors to desired position. This position will be saved as MEMORY "1". If message center displays SAVED TO DRIVER 1, 2 seconds after switch is released, go to next step. If specified message is not displayed, go to step 19).
  11. Autolamp Delay & Panel Intensity MEMORY "1" Test  - Turn park lights on. Adjust panel light intensity. This adjustment will be saved as MEMORY "1". Adjust autolamp delay time. This adjustment will be saved as MEMORY "1". If message center displays SAVED TO DRIVER 1, 2 seconds after switch is released, go to next step.
