moistwurm Posted February 28, 2015 Share Posted February 28, 2015 I've have a problem with the ABS and TC lights illuminating intermittently. The HDC does not light. They can come on after braking, but usually come on randomly more often in warm weather. I've read about the brake light switch, but the brake lights are fine. Before I spend money on ABS diagnostics, has anyone fixed a similar fault? Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted March 3, 2015 Share Posted March 3, 2015 Just because the brake lights works doesn't mean the switch is 100% OK, it has multiple contacts, if one contact stops working the brake lights might work fine but the ECU cannot be sure when you're pressing the brake pedal.

moistwurm Posted April 6, 2015 Author Share Posted April 6, 2015 Update: Replacing the accelerometer near the handbrake has kept the lights off. ABS is working, looks as though its fixed! Quote Link to comment Share on other sites More sharing options...
OrenDevine Posted September 21, 2015 Share Posted September 21, 2015 The ABS use the Embedded system based controlling. Which controls the hydraulics and Pneumatics by using the Microcontroller or Microprocessor. If you are facing the problem in the controlling of your ABS must check its Electronic part. You must check the break light contacts also. Quote Link to comment Share on other sites More sharing options...
