I just had the Liberty into the dealer for free PA state inspection and to read the ABS codes as well. They use a DRBIII tool with a vehicle modle specific memory card to read the codes I beleive .
Thought for sure I was going to hear it was a front wheel speed sensor due to the rusted nature of the hub. Well they said they could not communicate with the Anti Lock Brake Control Module. They reset the main connector to the ABM and the light went out only to re-appear when they drove it. They said it would be around $425 for a new ABM that they beleive included the pump. I told them I'd look into it further. I wonder if I took it out when I accidently set a wrench down on the battery and it shorted across the terminals for a split second?
Ebay had a few DRBIII tools going for several thousand dollars, so I think I'll hunt for a used '05 ABS module. Any one know if the are year specific or engine specific. We have an '05 CRD and it appears to be an Ate brand controller not the Teves mark25? shown in the shop manual I have.
Shorting out the battery will not fry just one electronic controller,it will take almost all of them out but most likely nothing will happen.If they can not communicate with the ABM and if they did the correct diagnostic path and came to the conclusion the ABM is bad then yes you will need a new one and it will need to be programmed to your vehicle,a used one will not work if you have a sentry key and not to mention the DRBIII will be needed to bleed the ABS pump anyways(a must,you will never get the ABS pump bleed without the DRBIII).You can find DRBIII's for sale but you will be very limited without access to Chrysler's website,just basically a very expensive code puller all it will be and only for Chrysler vehicles('09+ need the Starscan).
