WARNING: This page is about a different car, the 1997 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect 42-pin harness connector C214. Harness connector C214 is located below driver's side of instrument panel, to the left of steering column. See Figure .
  2. Using ohmmeter, check resistance between terminal No. 2 (Tan/Orange wire) on Data Link Connector (DLC) and terminal No. 32 (Tan/Orange wire) on female side of harness connector C214. See Figure . Note resistance and go to next step.
  3. Using ohmmeter, check resistance between terminal No. 10 (Pink/Light Blue wire) on DLC and terminal No. 33 (Pink/Light Blue wire) on female side of harness connector C214. See Figure . Note resistance and go to next step.
  4. If resistance is 5 ohms or less on both circuits, go to next step. If resistance is more than 5 ohms on any circuit, repair open circuit on Tan/Orange wire or Pink/Light Blue wire between DLC and harness connector C214. Repeat TEST A  .
  5. Disconnect 16-pin connector C455 from Driver's Door Module (DDM). The DSM is located inside the driver's door.
  6. Using ohmmeter, check resistance between terminal No. 15 (Tan/Orange wire) on connector C455 and terminal No. 32 (Tan/Orange wire) on male side of harness connector C214. See Fig 1 . Note resistance and go to next step.
  7. Using ohmmeter, check resistance between terminal No. 16 (Pink/Light Blue wire) on connector C455 and terminal No. 33 (Pink/Light Blue wire) on male side of harness connector C214. See Fig 1 . Note resistance and go to next step.
  8. If resistance is 5 ohms or less on both circuits, go to next step. If resistance is more than 5 ohms on any circuit, repair open circuit on Tan/Orange wire or Pink/Light Blue wire between harness connector C214 and connector C455. Repeat TEST A  .
  9. Inspect terminals No. 15 and 16 on connector C455 for damage. Also inspect corresponding pins on DDM for damage. If terminals on connector C455 and pins on DDM are okay, replace DDM. Repeat TEST A  . If terminals on connector C455 or pins on DDM are damaged, repair as needed. Repeat TEST A  .
