Just got this new to me MM. The ABS light, brake light, and T/C light are on. The brakes seem to function fine. I have checked all the tires for correct air pressure and put them at 36 psi, the brake fluid res is full. The front and rear tires arent mixed up, factory tires. I have given the wiring a quick look over and everything looks fine. I checked all the fuses. Any thoughts on where to look next? any checks to do? any ideas? throw em at me. Id really like to solve this.

Thanks for any help you can provide.

Did you get a warranty with this car?

Sounds like bad ABS/wheel speed sensor but strictly a guess

See about pulling codes for this. It could be a bad sensor in the rear.

I got a tuner with the car, an Excalibrator 2, havent really looked into it much. Can I pull codes with it?

Had the same issue on my DTR, you may want to PM frdwrnch, he's the one that steered me on to the fix.

The xcal won't be able to pull codes for wheel sensors. Gotta go to a dealer and use their scanner. Better than just swapping parts until you hit on the right one. It does sound like a wheel sensor.

Ok, using the Oasis repair manual, I got some ohm values on the sensors. I tested the resistance on the sensors, (1200-1800 ohms in the front), mine were 1300, Ok there. (1300-1900 ohms for the rears), mine were 1700, Ok there too. I tested the brake fluid magnetic switch, that checked ok too. Retested all the related fuses with an ohmmeter. Emergency brake switch checks out too. So whats left? the ABS module? the pump? Damn, i wanted to avoid the dealer/stealer.

Check the ABS sensors at each wheel for broken or frayed wires, also check to see that all the sensors have their bolts intact and are tight.

did you do a tire rotation lately that will set of the lights to go off make sure the right size of tires are in the right place

To be 100% sure 235/50 up front 245/55 out back

good point there--in the beginning that was a problem -------another great heads-up-been so long since that problem has appeared--almost forgot-------WTG.!

Do these lights come on and stay on at start up? Wheel speed issues usually prove out the lights initially but throw the light at about 7-12 mph when they don't see the input from one or more sensors. If the lights (ABS and Red Brake light) stay on after startup then there may be a low fluid concern which shuts down the system and throws both lights, there may be no power or poor ground to the ABS module, or there may be a critical electrical problem in the ABS system. I recommend you check all the fuses and the fluid level and if those are OK you need to find a means to scan it. Sometimes the dealer is not a bad option if the investment in diag saves you from throwing expensive parts at it.

Yes the tires are in the right places, the brake fluid is full. The lights are on at startup and stay on all the time. So its not like they come on once the system doesnt see a sensor. I disconnected the battery for about a half hour and that didnt clear it. Im starting to think its a major fault in the module or something. All the brake or ABS related fuses are good in the fuseblock inside the car and in the main block under the hood. The guy i got the car from claims the lights all came on the first time he drove it after taking off the winter wheels (CVPI steelies). The car has 22k on it and everything looks very clean and non corroded. I also pulled the back two sensors and cleaned them, they had some rust particles on them, but all the sensors check out with the ohm meter.

Probably gonna take it in.

If the TC is shut off in the tune, these light will be on and never go off.

Matt In Detroit
05-11-2009, 08:10 PM
The previous owner bought the car with the tune already installed. He claims he drove it for 18k miles with no lights then once he took the winter wheels off, maybe just a co-incidence that something failed? I considered pulling the tune and reinstalling it to see if it might help, but im new to all that and not totally comfortable doing it. So im doubtful its turned off in the tune.

No chance on pulling codes?

Matt In Detroit
05-12-2009, 06:52 AM
I called around this AM to a few auto parts stores, they can pull codes for check engine issues but not brakes. So, looks like ill take it in to the dealer to get them to pull codes. Im betting its the module, thats one expensive M'fer from the little bit of investigation ive done.

Take the harness out of the ABS module and inspect it for corrosion.
Then plug it back in.

Matt In Detroit
05-12-2009, 07:07 AM
Did that a couple of times, no corrosion, looks very clean, like new. I checked both connectors, the big one on top and the smaller one on the bottom that goes to the ABS motor. Disconnected the battery all night, lights on at startup this am.

Matt In Detroit
05-12-2009, 12:44 PM
Im going to run a few more tests tonight to check for power at the module connector and test the ABS motor to see if it works. Im basically down to determining if it is the module, everything else checks out ok. Oasis has a great troubleshooting section that walks you through which pins to check for voltage and such, so ill see tonight. I also have an appt at the dealer for tomorrow AM to get it checked out to verify. The module from the dealer is Marauder specific --$606. I found a place on the web that rebuilds them for $160. Id sure love for it to be a $20 brake fluid switch but everything else checks out good. If i determine its the module and the dealer does too, then ill probably go the rebuild route.

Matt,

Have you got a custom tune in it?? If so try to return it to stock and see what happens!!:beer:

I had a really bad tuning experience in 2004 but didn't realize it until I loaded the Diablo blower tune.....DISASTER.....dash looked like a Christmas tree!!!:mad2:

Just a thought??:cool:

Matt In Detroit
05-12-2009, 05:22 PM
I thought about pulling the tune and reinstalling it. But the fact that the previous owner put 22k on the car with no lights or issues tells me its not the tune. I did just do a few more checks. Per the oasis troubleshooting guide, I have power at the correct pins on the module connector, so that tells me the power is getting to the module. Then i put 12v directly to the ABS motor, it spooled right up. So looks like the power is getting to the module but not being put to the motor from the module. So I think its the module. Im dropping it off at the dealer in the AM to get it checked. If they say its the module, ill start looking for one or send mine to get it rebuilt. Ill make sure to follow up for the record.

Matt In Detroit

Ok, dealer just called, the ABS diag (code B1342) says the module is bad. The price tag? $970 bucks out the door, parts and labor. That wont be happening. So anyone have a good module lying around for sale before I send mine out for rebuild?

Spectragod
05-13-2009, 08:51 AM
Just did a module on a CV with the same code. There is no troubleshooting with that code, just to replace the module. I think my cost on the CV module was $420 or so, with a $100 core, labor is only .5 to change it out though. I don't know how they came up with $900+.....

They tell me that module is marauder specific, sounds possible with the different tire sizes. Zack, I did try rapping it with a mallet (we must think alike) to see if it might come to life, no luck. Im gonna pull the module and look at it real good. Ive had good luck fixing things like that before, bad solder joints, water intrusion, whatever. Worst case, ill send it out for a rebuild, $160 @ Module Masters.

PM TooManyFords, Im pretty sure he is/has deleted the module from his car.
He might have one available.

The non t/c ABS module will not fit onto a t/c equipped HCU. I have tried this.

Correct, that's why I listed both #'s. Sounds like the rebuild is the wway to go though. I would however like to crack one of those ECU's open and see what makes it tick.

Just pulled off the Module, its a wierd piece of electronics. Has a bunch of cylindrical looking solenoid things that fit over some studs on the aluminum housing. They were supposed to slide off. One was so siezed on the stud it tore it out of the module. Not sure if thats bad or not but im gonna send the whole shootin match over to a rebuild place and see what they can do with it. I too wanted to crack this thing open and see if i could fix it myself but its sealed up real good. Im not going to chance busting it up.

Spectragod, I might take you up on your pricing if things go that way. Ill let you know.

Matt In Detroit

Sent the module out to Modulemasters last week, got a call back that they needed to replace one of the solenoids in it. They said otherwise the module looked great Charged me $25 + $8 shipping, $33 bucks. So I should get it in a day or so and put it back on to see if my issues are solved. Ill post again and let you all know. Ill be stoked if my repair bill went from $900 to $33.

Matt In Detroit
05-28-2009, 06:34 PM
Unbelievable. Installed the repaired module just a few minutes ago. No Brake light, no TC light, no ABS light. Problem solved! $33 my cost. And to think they wanted $900+ at the stealer for the new module and labor.

My kudos to www.modulemaster.com (http://www.modulemaster.com)

i have the same problem like Matt!
but i am in Germany, very difficult to order parts!
@ Spectragod:
can you order me the part and can you send it to me too germany?

Coupe, send it for the rebuild, much cheaper. Look up modulemasters on the web and contact them.

The link is in my post, 2 posts back.

Opened how? you just took the module off the car.... or you took it off the car and then cracked open the sealed case?

Either way id call them or send it to them anyway, they will tell you if it is unrepairable.
