decided to finally replace the ABS module , ( Tired of seeing the Codes ) prior to module replacement i inspected all 4 sensors and found 1 sensor wire OPEN . replaced sensor wire with OEM component and all 4 sensors .
Replaced ABS module , ( Did not disconnect battery, maybe mistake # 1 ? ) Turned on ignition
1) Gear box fault code
2) ABS Fault codes
3) Engine failsafe code
4) Sometimes get "Incorrect part fitted " Code
Vehicle will not turn over
Checked battery it was down to 50 % , charged battery ( Didn't disconnect leads on battery , maybe mistake # 2 ? )
Removed terminals and fully charged battery out of car
reinstalled battery
Same codes ?
Any ideas anyone ?
( Yes i,m proficient with a Volt / Ohm meter )
PS 2000XK8 recently serviced no issues until this

 

You should always disconnect the battery before undergoing any electrical repairs.

You need to have someone with a scan tool capable to clearing all of these codes to see which stay, a tool such as autoenginuity, any snap-on or matco scanner, there are many other tools that can clear all powertrain, airbag and abs codes. Point is you don't need to see the dealership, any independent shop can do it.

There are some codes that will clear out on their own when everything is reconnected.

Keep us posted to see which codes stick around.

Good luck!

 

P.S. I have also had situations where I had to clear codes two or three times before they were gone forever.

Also I forgot to ask, is the car running properly? Have you been able to put the car in a severe braking situation to test the anti-lock brakes? (do this safely on an empty road)

 

Sorry for breaking protocol by incorrect location of specific year of XK will never happen again .

 

Update : Connected the Scanner , it will not communicate with the car . Mechanic in search of a different brand of scanner .

 

You may not get a response until you identify the vehicle, assuming it's not the MGB.

Near the top of the forum page you will find User CP in the black bar. Gou there and you can add your signature and car info to your messages.

 

it's a model year 2000 xk8.

What kind of scanner did your mechanic use?

It's concerning that the scanner can not communicate.

 

I've moved your other identical thread from XK/XKR forum, merged it with this one and cleared out the duplicates.

Sorry for confusion, I was asking robiair what year/model, didn't realize you were answering for him.

 

Just about any generic scanner should connect. maybe the ECM is damaged.

 

Did you check all of the fuses? Engine and body, there is one fusebox in the engine bay, two in the cabin and another in the trunk.

It may seem silly to ask but everyone has over looked this at least once, myself included haha

Also, check for mice droppings and the distinct mouse pee smell. I can not count the number of cars I have repaired that mice have torn up, they nest inside cars and love to chew on wires.
This would be a possibility as to why the scanner can not communicate.

Diagnosing a faulty pcm can be very tricky and expensive. Hopefully yours is fine, however you should keep it in mind.

Good luck!
