Test G: No Response From Driver's Seat Module (DSM)
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.
- 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 .
- 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.
- 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.
- 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 .
- Disconnect 16-pin harness connector C301. Harness connector C301 is located below driver's side front seat and is a square-type connector. See Fig 1 .
- Using ohmmeter, check resistance between terminal No. 5 (Tan/Orange wire) on female side of harness connector C301 and terminal No. 32 (Tan/Orange wire) on male side of harness connector C214. See Fig 1 . Note resistance and go to next step.
- Using ohmmeter, check resistance between terminal No. 1 (Pink/Light Blue wire) on female side of harness connector C301 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.
- 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 harness connector C301. Repeat TEST A .
- Disconnect Black 26-pin connector C311 from Driver's Seat Module (DSM). The DSM is located below driver's side front seat.
- Using ohmmeter, check resistance between terminal No. 5 (Tan/Orange wire) on male side of harness connector C301 and terminal No. 25 (Tan/Orange wire) on connector C311. See Fig 2 . Note resistance and go to next step.
- Using ohmmeter, check resistance between terminal No. 1 (Pink/Light Blue wire) on male side of connector C301 and terminal No. 26 (Pink/Light Blue wire) on connector C311. See Fig 2 . Note resistance and go to next step.
- 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 C301 and connector C311. Repeat TEST A .
- Inspect terminals No. 25 and 26 on connector C311 for damage. Also inspect corresponding pins on DSM for damage. If terminals on connector C311 and pins on DSM are okay, replace DSM. Repeat TEST A . If terminals on connector C311 or pins on DSM are damaged, repair as needed. Repeat TEST A .
