No Communication With SCIL Control 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.
- Disconnect SCIL control module 26-pin connector C288. See Fig 1 . Measure resistance between ground and SCIL control module 26-pi n connector C288 terminal No. 14 (Black/Light Blue wire). See Fig 2 . If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Black/Light Blue wire, then retest system.
- Disconnect SCIL control module 26-pin connector C287. See Fig 1 . Measure resistance between ground and SCIL control module 26-pi n connector C287 terminal No. 7 (Black wire). See Fig 2 . If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Black wire, then retest system.
- Measure voltage between ground and SCIL control module 26-pin connector C287 terminals as follows:
- Terminal No. 14 (Red/Orange wire).
- Terminal No. 26 (Light Blue/Red wire).
- Terminal No. 15 (White/Light Green wire).
- Terminal No. 11 (Dark Blue/Light Green wire).
If battery voltage is present at each voltage measurement, go to MODULE COMMUNICATIONS NETWORK article to diagnose network concern. If battery voltage is not present at any voltage measurement, repair open in suspect circuit(s), then go to next step.
- Disconnect SCIL control module 16-pin connector C289. See Fig 1 . Measure voltage between ground and SCIL control module 16-pin connector C289 terminals as follows:
- Terminal No. 5 (Brown/White wire).
- Terminal No. 6 (Orange/Black wire).
- Terminal No. 7 (Pink/Light Green wire).
If battery voltage is present at each voltage measurement, go to MODULE COMMUNICATIONS NETWORK article to diagnose network concern. If battery voltage is not present at each voltage measurement, repair open in suspect circuit(s), then retest system.
