Radio won't function after battery reconnect. Bass and treble lites flash on and off, but radio won't function. Have disconnected battery before and had no problem. HELP!!
I hope that this solution will help you:
When disconnecting and reconnecting battery, first disconnect the
(-) negative post first and connect it last.
Before you connect the battery cables again, wait 15 to 30 min. to allow the vehicle's computer to reset.
STEPS:
1. Set parking brake. Put it on park.
2. Turn off any accessories.
3. Start engine.
4. Run engine until it reaches operating temperature. Idle it for at least one min.
5. Turn a/c on and let it idle for at least one min.
6. With foot on brake and a/c on, put it on drive. allow to idle for at least one min.
7. Drive the vehicle for at least 10 miles to allow the computer to start the re-learning process.
8. This should be done to have the vehicle's computer to re-learn the idle and fuel trim strategy among other problems that disconnecting and reconnecting the battery may cause.
I hope this will help you.
Remember, if you want to reset the vehicle's computer, you should wait from 15 to 30 min. before re-connecting it.
The radio is in theft lock, you will need your unique code that came with the truck new to unlock it.
