Hi All,
Looking for some advice please. Long story short, I replaced the outer CV join boots, a massive struggle I have to say. After which a suspension height sensor fault, which was resolved by replacing it, also a front left ABS sensor fault which I replaced but it did not resolve the issue. During this work the battery went absolutely flat, I had not put it on charge or disconnected it, silly me!! I took it to a repair shop, they had it for three months!! During which time they diagnosed a faulty ABS module which they replaced with one I had bought on eBay. This did partially fix the ABS problem but not entirely. The other faults I have are related to the TCM and the TCCM. They were not able to fully diagnose the problems but I do not know how much time they actually spent looking at it. I also get errors related to stability control etc. I'm at a bit of a loss on how to proceed with this. If I take it to another workshop they will start from scratch and still no guarantee of it being fixed. I can get a used TCCM from eBay, TCM modules though do not appear to be available and a new one is approx. £3000!! I can get a used gearbox for £400-500. Any advice for me please, reputable repair shops maybe, mobile mechs with full JLR diags. etc. I'm in the Southampton area. Also just to say, other than the warnings on the dash the car drives fine, so there's nothing massively wrong.
Thanks in advance

The fault codes are required to get some idea of the possible causes of issues. L405 D350 SE Carpathian Grey D5 19" rims

Faults such as yours, after a completely flat battery might be related to the steering angle sensor losing its calibration.

With the engine running, turn the wheel from right full lock to left full lock a couple of times, do this whilst slowly moving forwards to give your tyres less of a workout.

Slim chance, but it could be as simple as that.

Thanks both, I do have the fault codes so I'll post them and also try the steering sensor recalibration. I'll post the codes when I find them. Thanks

Hi Guys,

Had to do another scan, this is the first since I got the vehicle back and this confuses me as the only work they I believe they did was to replace the ABS module but I'm not sure they actually did do that!! It seems to me that all the problems/fault codes link directly back to the ABS still, apart from maybe the TCM. I personally changed the front left wheel speed sensor, and tried three replacements, one of them being OEM!!

I tried the steering angle sensor reset but no dice!!

TCM(Transmission control module)
P2159-02 Vehicle Speed Sensor (VSS) B range/performance. Permanent

ABS(ABS control module)
DTC Description Status
C0031-25 Front left wheel speed sensor Permanent
U3002-81 Vehicle identification number Permanent

ADCM(Adaptive damping control module)
DTC Description Status
U0415-68 Invalid data received from ABS control module Permanent

PBM(Parking brake control module)
DTC Description Status
U0415-00 Invalid data received from ABS control module Permanent

TCCM(Transfer case control module)
DTC Description Status
U0415-00 Invalid data received from ABS control module Permanent

The VIN number fault on the ABS module would lead me to think it's not been coded to the vehicle?

The only thing is, I'm not sure if it has to be on the L322 - anyone else know the answer?

One thing I do know, is that wheel sensor locations can be mis-reported, I've had this on an early L322. In my case, the fault code said it was on the rear left, when in fact it was the rear right causing my issues.

To find out for sure, take the car for a drive and read the live values for all 4 wheel sensors. The one with an issue should show itself (EDIT ->> But you might have to drive in a circle to find out which is left vs right, as the inner wheel will go slower than the outer when turning in a circle).

Prob best to get a passenger to view the live readings, or record the trip on your diag tool and view them later, don't want any bumps!

So the ABS module was likely changed but not coded correctly??

Live values on my diag tool do show the left wheel speed sensor to be faulty but perhaps it is the RHS

Just remembered you said the above, you didn't get the ABS reluctor ring covered in CV grease did you? That'd likely cause a wheel speed mis-reading...

It seems doubtful, as you must be quite handy with the spanners to remove the driveshaft and do a CV boot on your own (unless you cheated and used one of the glue together ones! )

Just wondered if the events are somehow related?

If the comms faults regarding the ABS module are the only faults once the speed sensor fault is rectified and everything works then it is possible that the VIN mismatch is all that is wrong and can be ignored. L405 D350 SE Carpathian Grey D5 19" rims
