Hi,
the following equipment stopped working on my 2000 Crown VIC.
- Keyless entry (key fob and door pad)
- Drivers window one touch down
- Power locks
- Trunk release

All fuses & relays are good (under hood and dash)

What should I check next?
Do you
have the same problem?

Under the hood. Not fuse or relay, but circuit breaker.

They both control all the symptoms that you described.

It sounds like a Body Control Module or a alarm control module has failed. Do a pin to pin check using a wiring diagram with a voltmeter to check continuity of all circuits in that system.

After reading your email and some of the diagnostics, I believe it is your DDM (driver door module being faulty) with the alarm LED blinking. Most vehicle use BCM, but in your vehicle it is called a DDM instead. There is no need for re-programming of the new DDM.

TEST N: ALL DOOR LOCKS INOPERATIVE

1.Turn ignition switch to RUN position. Using master window/power door lock control driver window one-touch down feature, roll window down. Lock and unlock power door locks using remote transmitter. Unlock driver door using keyless entry keypad. If any of these functions operate properly, go to step 6 . If none of the functions operated properly, go to next step.

2.Remove key from ignition. Disconnect Driver Door Module (DDM) 12-pin connector C518, 18-pin connector C519 and 4-pin connector C520. Reconnect DDM connectors. Turn ignition switch to RUN position. Using master window/power door lock control driver window one-touch down feature, roll window down. Lock and unlock power door locks using remote transmitter. Unlock driver door using keyless entry keypad. If any of these functions operate properly, go to next step. If none of the functions operate, replace DDM.

3.Remove key from ignition. Disconnect Driver Door Module (DDM) 12-pin connector C518, 18-pin connector C519 and 4-pin connector C520. Re-tension or re-crimp all DDM connector terminals to fit tighter. Reconnect connectors. Access ground points at base of driver and passenger "A" pillar. Remove, clean and tighten grounds. Apply dielectric compound to ground point after tightened. Reconnect all DDM connectors. Turn ignition switch to RUN position. Using master window/power door lock control driver window one-touch down feature, roll window down. Lock and unlock power door locks using remote transmitter. Unlock driver door using keyless entry keypad. If all of these functions operate properly, system is okay at this time. If some or all functions do not operate properly, replace DDM.

4.Turn ignition off. Disconnect driver master window/door lock control switch 20-pin connector C503. Measure voltage between ground and driver master window/door lock control switch connector C503 terminal No. 5 (Light Green/Yellow wire).
See Fig. 8 .

If more than 10 volts exists, go to next step. If 10 volts or less exists, repair open in Light Green/Yellow wire. See WIRING DIAGRAMS .

5.Connect driver master window/door lock control switch 20-pin connector. Discconnect DDM 18-pin connector C519. Measure voltage between ground and DDM 18-pin connector C519 terminal No. 2 (Pink/Light Green wire).
See Fig. 1 .

If more than 10 volts exists, go to next step. If 10 volts or less exists, repair open in Pink/Light Green wire. See WIRING DIAGRAMS .

6.Measure voltage between ground and DDM 18-pin connector C519 terminal No. 10 (Pink/Yellow wire). See Fig. 1 .

If more than 10 volts exists, go to next step. If 10 volts or less exists, repair open in Pink/Yellow wire. See WIRING DIAGRAMS .

7.Turn ignition off. Disconnect driver master window/door lock actuator connector. Measure resistance of Pink/Black wire between DDM 18-pin connector C519 terminal No. 8 and driver master window/door lock actuator connector. See Fig. 1 . If resistance is less than 5 ohms, replace DDM. If resistance is 5 ohms or more, repair open in Pink/Black wire. See WIRING DIAGRAMS .

I can't post the entire wiring diagram here (too small to see) If you need a wiring diagram, please let me know. I will email it to you.

Initially, I didn't even think the DDM was the problem until my boss suggested looking into the BCM. Then, you know, the "thinking light bulb"turned on, and "gee, why didn't I think of that". So, here we are.

Anyway, your scanner won't do any good. The DDM only responds to New Generation Star (NGS), a Ford only scan tool.
