The wrench warning light can come on for many different reasons in your 2006 Ford Explorer. A Ford dealership can diagnose the problem. Make sure the oil doesn't need to be changed, that will cause it to come on.
If you mean that you have a warning light on, then once the problem that is causing the airbag warning light to come on is diagnosed and fixed, the light will reset itself.
I have a warning light come on which is a circle with an excaimation point inside. What does it mean?
At least 35 miles.
Over 100 different reasons.
Defective sensor
Usually the appropriate warning light on the dash will come on if the alternator is not producing current. If you don't trust the warning light, take a volt/ohm meter and (making sure it is set on the DC reading scale) connect it across the output terminals of the alternator to determine if any current is being produced.
Check your brake fluid level in the brake master cylinder in your engine compartment when it is low your brake warning light will come on
From what I've experienced it's usually low on brake fluid.
check the brake fluid level. check all the brake linings for thickness.
because the battery needs charged or need a whole new battery
No, the red brake warning light will come on.
