Warning lights

ReelBandit · 12-14-2010, 02:39 PM

On my dash, the brake light and the battery light come on and off simultaneously. When one is on the other is on. I've had my alternator checked and it's ok. I've checked connections at the battery and the alternator. Also checked the switch for the hand brake and brake fluid level, all are ok. They don't stay on all the time. Any ideas?

I had the same two lights come on a while back and then also had the alternator checked with no sign of a problem. Then the lights went off and have not come back on since.

Yes I am showing a knock sensor code, which I am getting ready to fix, but nothing else. It just seems that there is something is common with the both of them, I just don't know what else to look for.
