Hello folks.
I'm looking for some guidance to help narrow down a problem with my 2001 TD5 Disco traction control. Only had it a week and I've no real experience of Disco TC. But, had plenty of other trucks and cars with TC. I'm no mechanic, but I think this is within my limits.
Scenario 1: Good grip, such as tarmac or hard compacted ground. On full right hand lock moving forward slowly, such as parking, the TC light comes on and I hear the buzz of (I assume) the ABS unit doing it's thing. However, there's no discernable "braking" going on. IMO the TC shouldn't activate at all given the surface and available traction.
Scenario 2: Driving along a normal metaled road, say 30 MPH, the nearside hits a drain grate that has dropped, say 1", or a small pot hole. You get a noticable thunk as the suspension absorbs the sudden dip, which you'd expect I think. But, the TC light come on, the ABS unit buzzes and, again, no discernable "braking" going on. If I had to say, I would be inclined to say it happens when the front wheel hits the pot hole.
I read some other posts and I'm guessing that there is likely to be an issue with the nearside front ABS sensor, which is where I plan to look first. But, the lack of any "braking" when the TC light comes on and the ABS unit buzzing concerns me as the other posts indicate that this usually results in the truck being braked.
Given the above, am I right to look at the near-side front ABS sensor first or should I be looking else where first?
I have a workshop manual with the details of how to remove the callipers & disc to get to the sensor. But, before I go down this route (which will be more spannering than I have done in about 20 years), I thought it best to consult with the community.
Thank you in advance.
