Test A: No Communication With SCIL Module

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.

Ensure ignition is off. Disconnect connector C288 from Steering Column/Ignition/Lighting Control (SCIL) module. See Figure . SCIL module is located behind passenger's side of instrument panel, to the right of glove box. SCIL module contains one 16-pin connector, one 22-pin connector and two 26-pin connectors.
Using ohmmeter, check resistance between ground and terminal No. 14 (Black/Light Blue wire) on connector C288 for SCIL module. See Fig 1 .

If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open ground circuit on Black/Light Blue wire to SCIL module. Using scan tester, perform On-Demand Self-Test on SCIL module to ensure problem has been repaired.
Disconnect connector C287 from SCIL module. See Figure . Using ohmmeter, check resistance between ground and terminal No. 7 (Black wire) on connector C287 for SCIL module. See Fig 1 .
If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open ground circuit on Black wire to SCIL module. Using scan tester, perform On-Demand Self-Test on SCIL module to ensure problem has been repaired.
Using voltmeter, check voltage between ground and terminals No. 11 (Dark Blue/Light Green wire), No. 14 (Red/Orange wire), No. 15 (White/Light Green wire) and No. 26 (Light Blue/Red wire) on connector C287 for SCIL module. See Fig 1 .
If battery voltage exists at all designated terminals, a communication network problem exists. See COMMUNICATION NETWORK FAILURE under TESTING in MODULE COMMUNICATIONS NETWORK article.
If battery voltage does not exist, check for defective fuse or wiring circuit from fuse in fuse panel to connector C287 for the SCIL module. For terminal number, wire color and fuse application, see FUSE & WIRE APPLICATION TABLE. Fuses are located in the fuse panel at driver's side end of instrument panel, near door opening. Repair fuse or wiring circuit as necessary and proceed to next step.
Disconnect connector C289 from SCIL module. See Figure . Using voltmeter, check voltage between ground and terminals No. 5 (Brown/White wire), No. 6 (Orange/Black wire) and No. 7 (Pink/Light Green wire) on connector C289 for SCIL module. See Fig 2 .

If battery voltage exists at all designated terminals, a communication network problem exists. See COMMUNICATION NETWORK FAILURE under TESTING in MODULE COMMUNICATIONS NETWORK article.
If battery voltage does not exist, check for defective fuse or wiring circuit from fuse to connector C289 for the SCIL module. For terminal number, wire color and fuse application, refer to the FUSE & WIRE APPLICATION table. Fuses No. 7 and 13 are located in the fuse panel at driver's side end of instrument panel, near door opening and fuse No. 12 is located in engine compartment fuse box at driver's side of engine compartment, near spring tower. Once repair is complete, reinstall all connectors and use scan tester to perform On-Demand Self-Test on SCIL module to ensure problem has been repaired.
