1998 Ford Windstar REAR TAIL LIGHT OUT - NOT BULB OR FUSE

**stop press**there is another module? GEM generic electronic module. Behind dash left side of steering column. The data lines from this module only go to the turn signals at the rear? And front park/turn signals? Have you got a feed to the the light that is out? I think it is likely you have a break in the brown live wire to the lamps both lives go to a connector behind left kick panel. I don't think it is anything to do with a control module. Simply a break in the live wire to the light that is out. Try wiring a live from a light that is working to it?

I have checked the wiring diagram for the ABS/TC module and cannot find any output wires to the rear lights?

DESCRIPTION & OPERATION
Vehicle has 2 module communications networks. The Powertrain Control Module (PCM) and Anti-Lock Brake System/Traction Control (ABS/TC) module (if equipped with traction control) are connected to the multiplex communications network through a pair of twisted wires or BUS. The BUS network is also referred to as Standard Corporate Protocol (SCP). The BUS consists of (+) circuit No. 914 and a (-) circuit No. 915. The air bag diagnostic monitor and all other optional modules, the Generic Electronic Module (GEM) and Anti-Lock Brake System (ABS) control module (on models not equipped with traction control), are connected to the ISO 9141 diagnostic communications network through a single wire (circuit No. 70). Both networks are connected to the Data Link Connector (DLC). This article is used to diagnose BUS and ISO communications network circuit faults. For module locations, see COMPONENT LOCATIONS table.
DESCRIPTION
The 4-wheel Anti-Lock Brake System (ABS) is designed to allow the vehicle to stop in the shortest possible distance while maintaining improved steering control under most conditions. Some models are equipped with traction control, which is integral with the anti-lock brake system.
ABS system consists of an Anti-Lock Brake Control Module (ABCM), Hydraulic Control Unit (HCU), 4 wheel speed sensors and toothed sensor rings, brake light relay, ABS and BRAKE warning lights, fluid level switch, brake on/off switch, and traction control switch. The ABCM and HCU are packaged in one unit identified as Electronic Hydraulic Control Unit (EHCU). The traction control valve block is 6" (152 mm) long, has 4 outlet ports and uses M12 (6 mm) tub nuts on tubes going to master cylinder.
NOTE:For more information on brake system, see appropriate DISC & DRUM article.

ABS/TC Module
OPERATION
When brakes are applied, fluid under pressure is transmitted through 4 normally open solenoid valves located inside Hydraulic Control Unit (HCU) to wheels. If Anti-Lock Brake Control Module (ABCM) senses a wheel is about to lock, based on input from wheel speed sensor, normally open solenoid valve is energized closed (pulsated) for affected wheel. This prevents fluid from entering brake circuit for affected wheel. The ABCM looks at sensor signal from affected wheel. If affected wheel is still decelerating, ABCM opens solenoid valve (pulsates), returning fluid back to HCU. When affected wheel comes back up to speed, ABCM returns solenoid valve to normal open condition, allowing fluid to affected wheel.
The ABCM monitors electromechanical components of brake system. A malfunction of Anti-Lock Brake System (ABS) will cause ABCM to inhibit system operation. ABS warning light will be illuminated on instrument panel. Normal power assisted braking will remain operational.
When ignition is placed in RUN position, ABCM will perform a self-check on ABS electrical system by illuminating ABS warning light for 2-3 seconds. When vehicle speed reaches 4 MPH, valves and motor will be briefly powered to ensure operation. During vehicle operation, ABCM monitors all electrical ABS functions and some hydraulic operations.
Malfunction of anti-lock brake system will cause anti-lock brake module to shut off or inhibit the system. Loss of hydraulic fluid in brake master cylinder reservoir will disable anti-lock system.

ABCM is located under battery tray in left front corner of engine compartment.

The REM thingy was buggin me so I looked around and found that the 1999 windstar SE ans SEL models had them fitted? None of the 89 models have them and the 99 LX model doesn't. So if ya looking to buy one, those are the models you need to look for. Also i'm sure someone can reprogram your old one. Looking into the modles with the rear module. It does indeed control the lights. And there is a module to control the fronts? It is possible this module is broken. But I would check the connections and output's before replacing the part? Could be costly even for a reprogram?

Ok here is what Dave H is trying to say. Your windstar is a late model and the other one is an early model so it doesn't have one. You need to find another late model one that is closer to or a 99 so it will also have one. I had a 98 early model and it did not have one it used the GEM instead. SO you should check with you local dealer for reprogramming or find one in a salvage yard to find a used one. Hope this helps.

Thanks Racefan. Yes that is what I was trying to say. It does seem that they are interchangeble across the range. But i'm sure ford will tell you this. I'm guessin a junky is gonna be your cheapest option on this fix. You will need to be looking for a 99 SE/SEL model. The LX does'nt have one?

Rear Electronic Module (REM)

REM is connected to SCP network. REM mainly controls the rear portion of vehicle. REM supports other locking features for all passenger doors and Right or Left Power Sliding Door Module (RPSDM/LPSDM) and liftgate. When Power Sliding Door (PSD) operation is requested, REM determines if necessary preconditions are met, and signals the appropriate PSD module for PSD operation (as equipped).

I have checked this out for you. On the 99SE and SEL models there are 2 types fitted #1 without elec sliding doors and without anti-theft built in, #2 with elec sliding doors and with anti theft built in, the parts interchange over the models. So if your vehicle has no elec doors then you need the first module.

#1 part #YF2Z13B524AA

It's the same part # for year 2000/01/02/03. As long as you have no power doors/anti theft fitted

hope this helps

I'm looking at OEM parts list. The modules only come as, with power doors and with anti theft or without both. The part # you have got does not show up on my system.I've just looked at 99LX the part #with both isYF2213B524BA. It's the same part right through to 2003. I haven't even got a BF listed anywhere.I'm not saying they are wrong. It's just all very confusin. Haha. Hope they get ya one soon. The price I have listed is $338 for the part # I have.?

You are right to be leary. I would be 2. All I was saying was I couldn't find that part # listed. You could go/ring fords service dept. And ask them whether they interchange. Or even if the part # has changed exlain you are having trouble tracking a used module down. Information is free. You could just ask how much is new part and ask for part #

I was saying call ford on the phone and enquire about part # to make sure the junky's are searching for correct part?

Wagsio. Let me know your van model and year and I will look into the REM for you. The only extra's. Ie differences when parts listed are power doors and anti theft. So really all modules should control rear heaters. Did you have any plugs left over? Or on the module was there space for another plug?
