on my moms 01 max the check engine light,slip light,tcs light,and service engine soon light come on and turn off every couple of miles. me and my mechanic scan it and no code or nothing, its weird. does any one know what can cause these lights to turn on and off all together like this.

 

I'm no expert, but it could be a bad ECU or BCM...

 

possible alternator issues. i believe these do not store a code.

 

Prolly coil packs or a brake sensor.

ZeTurk is no expert fo sho....

 

I vote for a brake switch issue. Then the alt.

 

If it were a alternator problem, the battery/abs lights would be on......

 

do the lights come on at idle?

do they stay on regardless of rpm range?

 

they stay on all the time regardless
