How to disable the cold diagnostic system
Saturday, November 05, 2016 2:30 AM
Hi all, I just had led headlights put in my 04 cav. And on start up they flicker. Was told it could be the cold diagnostic system. Is there a easy way to disable this cause them flickering every time I start car will lessen the life of the bulbs. Plus my service light is now on also. If you guys have any suggestions on that as well. I would greatly appreciate it.

U can buy leds that are "error" free. Usually pretty cheap if u shop online. There is another option, since u already have the lights u can buy a stand alone module to correct the issue. Not sure if it removes the engine light tho.

If you have a hid relay harness already and it is still doing it, you need to disable the drls. There is a write up on here. It involves cutting one wire.
