For the 3rd time, I damaged a rear ABS sensor out on a track, after rolling over a decent stick that got caught up underneath. First 2 times I ordered a rear aftermarket MN specific ABS sensor from Aliexpress.com, which include the magnet & wiring harness that connects back to the centre diff. Simple replacement fix worked both times. This time around however, I had a go at re-soldering the rear right ABS wiring. First time start up, the Brake warning, ABS, TSC & ASC lights disappeared, then all came back couple seconds later along with the brake warning light as well.
So at a recent service, I supplied 2 new rear abs sensors & asked the mechanic to fit them up, and replace a non-standard plug an tyre shop fitted up after ripping the rear left ABS sensor wires. Tyre shop couldn't get the factory plugs I guess so used basic 2 pin ones.
Anyway, mechanic's auto-sparky replaced the non-standard plugs with factory plugs, and installed the 2 new rear ABS sensors. Problem remained. They said the ABS module in the engine bay wasn't getting any signal from the rear sensors. They replaced the ABS module with a 2nd hand one, thinking thats the issue also. This time, TCS & ACS lights are gone, but still got ABS & brake warning lights. Then they replace the centre harness that interconnects the 4 abs sensors & I supply a full set of 4 new ABS sensors. Still same result. They recon no signal is being received up to the ABS module. The sparky is using an oscilloscope style tool that goes beyond measuring voltage and amps they tell me. So they're still chasing a wiring gremlin to resolve it.
Any advice on what this could be? I feel like the mechanic's are running out of ideas. They work on Triton's a lot and have been great to deal with over the years without ripping me off or doing poor work.
