Terence Bower Posted April 8, 2017 Share Posted April 8, 2017 Silly question but as I have mislaid my drivers handbook!! When switched off,so the dash warning light comes on as it should.Now yesterday,had to remove the rigth hand front caliper for servicing,during the time it was off I switched the ignition on but did not touch the tc switch but the warning light plus the other sliding car lamp came on.This surprised me as I have never seen it before. I assume it to be something to do with the brake circuit being broken,is this so?Everthing back to normal now its all together again.Should both of those lights come on when the tc switch is switched off? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Paddy78 Posted April 9, 2017 Share Posted April 9, 2017 Sounds about right. Without the front caliper the stability control is effectively unable to operate, so I would expect to see the tcs warning and another warning. Quote Link to comment Share on other sites More sharing options...
Terence Bower Posted April 9, 2017 Author Share Posted April 9, 2017 Thank you but if the tc switch is off,should I see both amber lights illuminated?Reason I ask is that turning tc off makes barely any difference.Tried the usual stuff in case the diff is just not playing and needs replacing.

Olly350z Posted April 9, 2017 Share Posted April 9, 2017 I had a very similar issue when I replaced my brake lines. Got to the drivers rear line and snapped it at the union as it had seized. Wasnt overly bothed as I knew I could get it trailered down to the shop. Obviously I had no brakes due to the snapped line, but thought I could at least move it on the drive. Nope Not sure exactly what it was, but the car sensed the lack of brake fluid, threw up both warning lights that you have and locked the differential meaning the car, even under its own power wouldnt move. It was like the handbrake was on. Im not sure how related both of these are, but thought I'd offer my input. Did you disconnect the lines?

Terence Bower Posted April 9, 2017 Author Share Posted April 9, 2017 Yes,very similar to what you had.Problem is I cannot get to the bottom of my diff issue.Visual inspection,cover off,all looks to be in order(didnt have time to remove it) no noises from it ,new oil but no lsd properties with the switch off😠Quote Link to comment Share on other sites More sharing options...
