03 Frontier-BRAKE & Battery Light??

[DougSweet]

Well, solved the Antilock Brake Light and Airbag warning light issue with a new alternator.

Now, my BRAKE light and the battery icon light come on after about 90 miles of driving. I can get rid of them by letting the engine run down to idle or turning on the fan or headlights or windshield wipers, or combinations of them. All run just fine with no noticeable loss of power.

The kicker is, I stop the truck, let it sit for a day, and the battery is dead. It starts just fine with a jump, and I've replaced the battery. The new battery does this, too.

Any suggestions?

Thanks in advance!
