If the module is off line, you need to check both power and grounds at the module to see what is missing. If that all checks out, then the module may have a fault.

Which car and engine is it?

 

2007 cooper s N14

 

It's a intermittent fault is working now. I hit a pot hole and all the lights came on ABS / airbag and the speedo stop. Then drive a bit more it came back to life. A bad connection somewhere.

 

Ugh.

I despise those.

Could be a chaffed wire shorting, could be an internal break, could be....etc.

Major PITA to chase down unless you get lucky and hit upon it right off. Being intermittent just makes it that much harder.

I don't envy the job you're about to do...

I have been on it for hours. Just went for a drive 10 miles all good. Just check when back after a hour lights all back on he dash.

 

Ugh, intermittent are the worst

 

I get a steering wheel sign with a 1 in it on the dash?

 

IIRC the steering wheel sign is to do with the PAS module

 

Are you sure it's not an exclamation point?

 

It could be, I know the abs brings on different faults.

 

hitting potholes that's not good. some mini cooper automatics have a issue with the speed sensor that is inside of the transmission and it will bush up against the insides of it and go bad. I don't use sport mode or anything myself. but one can tell that speed sensor is bad if it races through the gears, o course that is also providing a transmission fluid exchange was done at some point. unless it has under 100 thousand miles on the transmission.

 

Yes before it fails I get the code 5DAA power problem

 

That sounds very much like the ABS valves, or pump motor is on the way out

 

If so is it a new abs module or get the module checked and overhauled?

 

I would run a basic power and ground check at the connection just to be sure. If that checks out, I would certainly get it checked out

 

I have just plugged my code scanner in and no code. Tested abs pump and it worked. Intermittent faults I hate them.

 

Inters are the worst - a right pain.

You can not run meaningful tests if it is "working" - ugh

 

Have had such faults due to main battery failing gone weak , so if main battery over 5 years old likely cause , the system can see weak voltages as a fault with other things on self check when put ignition on , key with these cars to have a very healthy battery otherwise and i have done it you waste hours chasing faults that are not really faults , just needs a new battery

 

Thanks Mike will check out the battery.
