MY12 L322 4.4 TDV8 - AGP Battery 5 months old. BT IID Tool.

Repaired disconnected cables in the driver's floor wiring loom - Automatic headlights and windscreen wipers are now working correctly. GREAT!

BUT:

I then put the battery on overnight Ctek trickle charge as the doors had been open and closed a lot during the work.

Now experiencing a number of issues/changes:

The car now 'beeps' on lock and unlock which it never used to do and I did not program #possessed.
Neither glovebox - upper or lower opens.
Parking sensors both front and rear are now inoperative.

Errors on IID Tool - cleared and reappear with associated yellow warnings on the dash.

B1B36-96 (2F) - Front right outer sensor - Component Failure - internal failure

B1B40-96 (2F) - Front left outer sensor - Component Failure - internal failure

C0037-14 (AB) Rear left wheel speed sensor - General electrical failure - circuit short to ground or open

U0415-68 (AF) Invalid data received from ABS control module - Algorithm based failure - event information

U0415-81 (AF) Invalid data received from ABS control module - Bus signal/message failure - invalid serial data received

U0415-00 (2B) Invalid data received from ABS control module

U0417-81 (AF) Invalid data received from parking brake control module - Bus signal/ message failure - invalid serial data received

U0128-00 (2E) Lost communication with parking brake control module

So some notable electrical gremlin(s) - having read various threads I thought possibly start with ABS earth sensors in the front wheel arches?

Any thoughts/advice would be much appreciated. 2012 L322 4.4 TDV8 - Current
2012 AM Rapide - Current
2009 Discovery - Gone

Test drive with IID Tool - culprit is becoming clearer - just need to track down where the fault lies.

You might want to recheck your wiring repair in case you've mismatched a couple of wires.

Thanks Graeme,

Having rechecked the ABS sensor and the connections on the harness around the fix. I had a look at the connector just upstream from the repair. Wondering whether I had dislodged one of the pins. Opening up the connector there was clearly some corrosion.

A quick brush up with a toothbrush and some contact Cleaner and a bit of jiggery-pokery and all is back well again with (currently) no warning lights on the dash or on the IID tool!

So that’s automatic headlights, automatic wipers and even the satellite GPS has come back online! Although it was a protracted exercise!! 😂 🙈
