What sensor did you replace. I have the same lights that randomly come on for a second, I didnt get it scanned yet but I'm just curious what it could be. OBDII keeps history code so if the light came on and went off there should still be a code for what caused it to come on, right? Hopefully or I'm never going to get a code because the light literally flashes for a second and is gone, and its completely random.

 

That's why I suggested to buy a $3 can of CRC Electronics cleaner and clean it.

I now suggest that you do the key trick and see what the ODBII code is. DO a search and you'll find it.

 

Same thing happened to my 03 QC. As posted by another DF member it was infact the "rear wheel speed sensor" very easy to replace and not too expensive

 

if that dealer wont fix it take it to another dealer kicking and screaming. if you just clicked over your warranty they should honor it

 

.WHERE IS THE ABS FUSE LOCATED AT.

 

I got the same thing on my 03 ram 1500 the abs light the e brake light and my spedo bounces from 0 to like 30 up and down....its gotta be a sensor everything else seems to work fine...

 

Thats most likely the rear wheel speed sensor. No big deal! I would suggest, if you are mechanically inclined, fix it yourself. The dealership charges WAY too much to TCO this $40.00 item.

 

This weekend all my lights went on...the engine, brake, abs, all of them...then i had no whippers and brake lights...but the thing is the truck started and drove fine ....just all my gauges were all ****ed up the spedo wouldnt work the tack didnt work...battery and voltage gauge every thing cut out......

 

Did you stop to think that perhaps your brake pads are worn down to the point where some extra brake fluid has gone into the brake lines, to make up for the lack of pad...

And thus the overall fluid level in the resovoir has dropped to such a point that the brake lights have come on???



I have 40,000 km's on my truck, and I just had the same problem with the brake lights coming on... :P
Got my brakes done, and now the light went away...

 

Yeah we just did all 4 brakes and rear rotors...i also checked the fluid level and yeah its deffinitly not that....i think its the rear wheel spedometer sensor...
