Traction and cruise control turn off when headlights are turned on


Asked by May 22, 2012 at 10:20 AM about the 2003 Holden Commodore

Question type: Maintenance & Repair

Whenever I turn my headlights on, my traction and cruise control deactivate.
Could the fault be related to a faulty abs module? I have tested the cruise control module and it checks out.I drive a vyss series 2 commodore.

I would try to narrow it down by pulling fuses that are related to your problem then one by one put fuses back in and see if a particular circuit shows up as problem.

The Cruise Control fuse runs off the same as the power mirrors. If they are playing up the fuse is faulty or you have a break in the current somewhere I dont have traction control so i'm unsure if thats the same fuse also, sounds like when too much current flows through it cuts one of the things linked

I will try both options and see what happens.I believe though that the fault is in the abs module which is expensive to replace!!


I have now solved the problem.My son who is a mechanic diagnosed it.I had after market Altezza Led tail lights and this was causing the problem.Went back to the original tail lights and its as good as gold.

I had exactly the same problem. and exactly the same solution. Thank you very much. I can't work out why, but LED tail lights must confuse the ABS module

I have the exact same problem when I turn headlights on traction control off light comes on and I have no cruise control with headlights on but I have factory tailights any Ideas?
