I am looking at a 2007 which is showing an ABS fault. I had a 2000 (xk8) that also did this and was quite common to hard reset X100s which would reset sensors and such. I am not sure if these resets work on X150s. The process was to disconnect one terminal and touch it to the other (still connected) for thirty seconds. I’m hoping it’s something we can do on a X150 and hopefully get rid of that pesky light. Anyone know if this is doable?

 

Yes, disconnect both cables and touch them together. Also worth confirming the condition of the main battery.

 

Yup, don't know if the fault will clear. Get a OBD2 scanner if you are getting an XK/R. Either hard wired unit of a bluetooth unit with a phone or tablet program.

 

I too rather doubt a hard reset will clear the code and it could give you some undesireable effects.

Electronically the X150 is considerably more complex than the X100 and is extremely sensitive to battery condition and state of charge. A better approach would be a diagnostics session to determine the possible causes and then fix the problem.

I expect a hard reset will not clear any ABS codes.

However, they usually in effect go away if you fix the cause and drive above some threshold speed (10mph or whatever).

Otherwise, use a specific tool which can do it for your car model.

 

From the ELECTRICAL GUIDE TRAINING MANUAL - NOTE: A hard reset does not repair a fault condition. It simply brings all control modules back to their baseline condition. If a hard reset eliminates the symptoms, then further diagnosis is needed to determine the cause of the conditions, i.e. low battery causing a single control module to come off line temporarily.

Having said that, the ABS is controlled by the high speed can bus IIRC. I expect if one thing in that chain goes wrong, it's very possible another module downstream is affected or an upstream module is causing it. A hard reset will return the system to base and the problem may go away but imo it would be temporary.

 

Is this "Electrical Guide Training Manual" a J(LR) publication? If so, might be a good idea to post a link or generate a stickie, to add to our information base. If it's copyrighted then nevermind..!!!

 

Forgot to weigh in. Sorry. The ABS fault code is known to throw if the battery is not up to snuff.
