Thread: Traction control, Amigos and diagnosis of problem on Disco 2 TD5

I've had the TD5 2000 model for many years now and I have found that with mine, when I occasionally get the 'squealing brake's from lots of dry dirt roads, the amigos come on and it is usually random which wheel. Just over 202K now. The squeel following by traction control kicking it is the combination I know will fault the system.

I use the nanocom to reset until next time. Yes, I have been right through the system and cannot fault sensors, connectors or the blame given for suspect cables and I can just about tell when it will fault from the level of dust exposed which is not often as it is in only very dusty to bull dust conditions.

I believe this has been discussed as well given I had all intentions of finding the fault but now just accept it.

Have a look here Members with Diagnostic equipment map

You are correct, in that anything else is just a stab in the dark without diagnostics.

My diagnosis so far would be that the sensor on the front left is no good or the cable has a problem, what do you reckon and say ?

I don't think the diagnosis is necessarily correct.

The ETC is completely disabled for all three amigo's faults except a failed brake lamp relay so you are just identifying which wheel has no traction not which sensor has failed.

If you want to try identifying where the fault lies without diagnostics you can use the table of resistances on page 70-24 of RAVE (Last page of the Brakes: Description and Operation section) as a reference to measure resistances of the sensors, shuttle valve switch, and relay coils. If you have the sensors with the plug near the wheel arch, you can measure at both the plug and at the ECU to check for a wiring fault.

I'd suggest rechecking when the vehicle was built. 2003MY production began at the end of 04/2002 and all australian delivery 03 and 04MY D2's came with the diff lock lever and internals. There is a small plate that is riveted to engine bay between the passenger headlight and the airbox which will tell you the month and year the vehicle was built. The compliance plate date can be anything from one to twelve months later than the build date so is a red herring.

There is a sticky in the D2 forum with a bit of information about VIN's build dates etc.

The Nanocom will read any faults that the ABS ECU has logged. The faults identify a problem associated with a component. You still have to confirm what is causing the issue. A sensor fault for example can have multiple causes related to the sensor and sensor wiring. The fault codes basically narrow down the fault to a specific circuit and the type of error condition logged (short to 12V, short to ground, or open circuit for example) , rather than giving you the exact problem.
