Am I corect in assuming that if i have ABS pressure sensor issues that I need to replace the entire ABS module? or can I just replace a component of it (the pressure sensor)?

Also can anyone give me a general how to on removing the ABS module?

Thanks

 

the sensor is inside the module so yes if that is the problem you HAVE to replace the whole module.

but that rarely happens.

 

I have C1290 (Pressure Transducer Cuircuit Failure). It says that the ABS module reads higher pressure than it should and compared to the other sensors its higher. Do you think it could be a wiring problem?

 

it doesn't hurt to check the wire first before replacing a 2K component.

if in the end IS the ABS module, you should be able to get it to work at some bigger shop with the proper WDS kind of computer.

 

do you have any idea what i would check on the wire. All the pins look good and its clean but the guild in the service manual does not adress checking the module just the other side of the connector that goes to the car

 

you need to check for shorts in the wiring. it could happen.

also make sure all the connectors are nice and tight. oh yea that sounds good

 

whats the difference between these 2 modules
one has the connector vertical as in the repair manual and the other its horizontal?
Mine is horisontal but are they interchangeble or is one DSC and the other not?

anyone know if you can open the ABS module and clean it?

 

Not sure, sounds like it.

Nope.

Stop being cheap. do the diagnostic now start checking wires already.

 

wires are all good. Looks like it might be time for module replacement :'(

 

get a used one from junk yard. most of the time they will probably sell it to you under 100 bux.

 

ABS is a safety device so I would try and hit up a dealer

 

if i buy a used abs module and swop the pressure sensor would i still need to reprogram? because the sensor just bolts on i so could keep the rest of the module.

 

service manual tells us that we have to run it with WDS to make sure everything works.

doesn't hurt to try. might save u a ton.

 

So I swapped the entire ABS module with a used one I got from another member. The abs and tracction light are still on but when I scan for codes there are none. The scanner just says it can no longer communicate with the TCM im assuming thats some part of the ABS and its just because it is not programed to the PCM. So im headind into the dealer as soon as this damn snow melts to get it reprogrammed
Just thought id include an update incase any members run into this in the future

 

Just thought i would post a follow up incase anyone reads this in the future. I got the ABS reprogrammed today at Elite Mazda in Gatineau and it reprogrammed just fine with the used module they also replaced a fuse that blew as a result of the first failing module. No codes, No lights. Extreamly satisfied with the service!

 

Some good information here.
i have a bit of a problem with my abs/DSC on my 05 mt hi power from uk.
I have a stand alone ecu in my car with can bus, and got most of the stuff working but not my abs, does anyone know what signal/message the abs need to not get the mismatch code? I need info on the ID and message, so we can send the info to the abs unit.
Best regards Henrik

 

Henrik Andersen, if you're still interested in CAN frames for ABS/DSC please PM me, it seems I can help you

 

Which ECU? I'm having similar issues with my Adaptronic.

 

If you are running Adaptronic, I heard back from them that they know there is an issue with the DSC controller and are working on a fix.

When replacing the module, what fuse did they replace? Was it the 15 amp engine fuse ( 5th one down on the upper right)?
I got a really bad case of flat tire. Resulting in a spare that was smaller in diameter. Leading to what i think is ABS mudule failure. SYMPTOMS: ABS module makes highish pitch "bwerrrrrrrrrrr" noise. Engine won't start due to 15amp engine fuse keeps bursting.

Does this sound familiar? Im trying to connect dots.

 

My car had been throwing phantom ABS error faults since I got it few mos. ago (indicating bad RF wheel speed sensor even with new senor/wiring). These kinds of phantom faults can be caused by failing ABS module. I recently had ABS module rebuilt by ebay seller bba-remaninc for $95 and it no longer throwing the fault. Wish I had done that before spending $200 and hours replacing hub and wiring.
