My 2008 Patriot has bad ABS Module
As anyone else had a problem with their ABS module going south on them? My dashboard is lit up like a Christmas tree with the ABS warning light, the ESP light, the Skid light, the 4WD!! light and sometimes the check engine light.
A local garage put their computer on it and told the the ABS module needed replacing.:(
My Patriot is just 3 years old and has 49000 miles on it. This is not covered by the warranty and sucker is expensive. It seems a little early for this to be going bad on me. Does anyone know if this is a widespread problem? Thanks!

It happens,and no not a widespread problem and can happen on every vehicle regardless of who made it.

Granted most ABS pumps that I replace are due to idiot owners filling the brake master with ATF which is death to every rubber part in your brake system with a average cost to fix around $2500.

IMO get a second opinion from Jeep dealer, I've seen a few times where a generic code comes up and the dealers scanner pulls a more specific code and repair procedure.

Thanks folks, I have an appointment tomorrow at 7:00 am at the Jeep dealer for the diagnostics.

Whats a Jeep dealer charge for that out of curiosity? Volvo used to r@pe me for $175 diagnostic fee.

All of those same lights have gone off on me. I never checked the code but re-centered the steering angle sensor by turning the wheel lock to lock and that helped for awhile. Turned out to be an alignment problem.

Let us know what they came up with.

Looks like reasonably good news. According to the Jeep dealer service department it is on a wheel sensor, a $54 part vs several hundred dollars for the ABS module. They are ordering the part and I have an appointment Friday to have it installed, I'm crossing my fingers that that will fix the problem!
How they described the problem to me is as follows:
When the wheel sensor went bad the on board computer sensed this. Now all four wheels could no longer communicate with each other so the braking system/stability control/4 wheel drive system went to a default setting. This setting allows you to keep driving but Jeep is just operating more like a Jeep from the 1960s.
I noticed the ride is less smooth and the accelerating seems very mushy. They told me I could drive it but I would more likely go into a skid in an emergency situation and my gas mileage won't be very good.
I don't know how much the charge for the diagnostics will be, I am still waiting to hear from Chrysler corp on how much they will take responsibility for. That will be settled by Friday.

Thanks for the update.

Here's how it worked out:
I went to the dealer to have the wheel sensor replaced and the on board system reset. My Patriot is now running fine with no extra lights on the dashboard. They charged me a grand total of $50! Chrysler Corporation called it a warranty issue and covered the balance. This included the cost for all diagnostics and installation.
I really have nothing but praise and thanks for Chrysler Corporation and Franklin Jeep in Farmington Maine.

Hey Guys !

I have a 2008 Patriot, diesel in a limited - I am having the EXACT same problem that you describe..

I noticed it only happened after I took it in for a service and they insisted it needed a wheel alignment and balance ( despite the new cooper tyres being only 2000 km old.. )

the ABS light came on, the stability control light came on - intermittently and it felt like a skateboard..

The traction control light came on also, but I can turn that on and off with the switch..

I took it into the jeep dealer closest to me, and they insist that it's a faulty ABS control module ( @ $1000 plus fitting )... and if this ' doesn't fix it ' then I'm up for another $1,500 for an ' ABS PUMP ' ' plus fitting '.. which should see me out of pocket over $3,000....

I read, word for word what you wrote - and showed them the forum.. and the mechanic said he had never heard of it - so they put it back on the hoist and 'checked the sensors' - which I firmly doubt as he only seemed to want me to pay for the new pump and control module.. and told me he had ' checked the wheel sensors with the diagnostic equipment '.. I call BS on that one..

Can you get to these sensors to swap them out yourself ? is there a part number - and how hard is it to do ?

I want to do this, before I go dropping $3k on something that ' may or may not ' fix the problem..

I think I am having a similar issue as the last poster. 2009 compass and dealership states the abs module must be replaced. I saw where there was a recall for 2007 compasses. Anyone know how to replace the unit? Does the brake system have to be bled out? Any links to the part? I can seem to find it anywhere. Obviously can get from the dealership of need be
