Thread: Warning lights on after under body wash. Scan tool help

I suspect a wheel speed sensor circuit is causing the other systems to be unavailable as they require ABS to be operational.

Hi all thank you for the constant information. It is all very helpful. I took the Disco to Bundaberg Landrover today for a fault code read as this was all they have time for until next Tuesday. Due to being booked out .They reported communication fault codes in every module. Exact codes they will supply me tomorrow as they were having printer issues today. The most common code related to transfer control module. No visual signs of water damage, but most likely. All associated wiring, fuses and plugs were all ok. They couldn't give me a definite answer until further diagnosis next Tuesday. Hopefully once I have the codes I can continue the diagnosis as we are stranded here until repaired. The chance of drying out is very slim now it has been 4 days since problem happened. Fingers cross once I have the exact codes I'll be able to research and repair ASAP so we can get back on the road. Thanks again for the assistance so far.

Regards Richard

The transfer case module is not sealed, with the circuit board and connectors exposed to any sprayed water. The transfer case module is also a link between 2 sections of the high speed canbus (in 1 side and out the other) so if its processor fails then the canbus will be interrupted, preventing communication between the modules on either side.

I suggest that the transfer case module be removed, then remove the circuit board from its enclosure, washed in clean water and allowed to dry before being refitted. That was standard practice many years ago for mainframe computer circuit boards if subjected to water from a fire sprinkler system.

So you can "wade" into 700mm deep water, but just don't splash any water around.....hmmm. (-:

Gordon does say they are good for the wading depth even better,the engind compartment is sealed much better than lesser vehicles.Stopping and getting flooded or pressure washing the engine is a different story

Hi all, I replaced the transfer module today and had it programmed. Problem all sorted. Thank you all for your info.

Hi well done Richardli glad it is all fixed.

I do hope your trip will be trouble free

I know from experience that it's a great feeling to be back up and running. Not knowing the problem is the worst part. Enjoy.
