WARNING: This page is about a different car, the 2000 Ford Windstar and 1999 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If repairs to a module communication network circuit is required, see REPAIRING BUS WIRING
. If module replacement is necessary, see PROGRAMMING
and REMOVAL & INSTALLATION
- Turn ignition switch to OFF position. Disconnect Rear Electronics Module (REM) 22-pin harness connector C341. Inspect connector for damage. Repair as necessary. Connect REM connector C341. Connect Next Generation Star (NGS) tester to Data Link Connector (DLC). Turn ignition switch to ON position. Perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM. If response was REM: NO RESPONSE ON CKT914 (BUS+), go to next step. If response was REM: NO RESPONSE ON CKT915 (BUS-), go to step 4 .
- Turn ignition switch to OFF position. Disconnect NGS tester. Disconnect REM 22-pin harness connector C341. Measure resistance between REM harness connector C341 terminal No. 1 (Tan/Orange wire) and DLC terminal No. 2 (Tan/Orange wire). If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, replace REM.
- Disconnect in-line 16-pin harness connector C292. Inspect connector for damage. Repair as necessary. Measure resistance between male half of in-line harness connector C292 terminal No. 4 (Tan/Orange wire) and DLC terminal No. 2 (Tan/Orange wire). If resistance is less than 5 ohms, repair open in Tan/Orange wire between in-line harness connector C292 and REM. If resistance is 5 ohms or more, repair open in Tan/Orange wire between in-line harness connector C292 and DLC.
- Turn ignition switch to OFF position. Disconnect NGS tester. Disconnect REM 22-pin harness connector C341. Measure resistance between REM harness connector C341 terminal No. 2 (Pink/Light Blue wire) and DLC terminal No. 10 (Pink/Light Blue wire). If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, replace REM.
- Disconnect in-line 16-pin harness connector C292. Inspect connector for damage. Repair as necessary. Measure resistance between male half of in-line harness connector C292 terminal No. 2 (Pink/Light Blue wire) and DLC terminal No. 10 (Pink/Light Blue wire). If resistance is less than 5 ohms, repair open in Pink/Light Blue wire between in-line harness connector C292 and REM. If resistance is 5 ohms or more, repair open in Pink/Light Blue wire between in-line harness connector C292 and DLC.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
