Default Radio Stays On

Radio stays on when I turn the car off and get out of it. I believe the door switch is bad or dirty. Is the pad that you open the door with act as the door jam switch, or is there another switch I need to find?

Thanks!

Do the courtesy lights come on when you open the door?

What radio, since awake/sleep mod is done through the BCM, and the question on the courtesy lights, since if BCM is turning them on with the door button push, should be sending the sleep command to the radio as well. Since we know that the radio is getting the command to come out of sleep once the car starts, then either problem with aftermarket radio module, or problem with stock radio.

As for the commands to the radio from the NCN, the only difference should be on the awake command, alternator willl be running so have higher voltage to the devices, then when the alternator is off, and only have the battery voltage alone.
Note here, if you have a low voltage Battery start problem/car sat on the tender too long, could have glitched the module, and may need to do a hard reset on the modules by disconnecting the battery, touch the battery termials to each off away from the battery, then reconnect the battery, once the battery has been charged/is up to full charge.

As for BCM to radio commands, its done on the serial 2 bus, and if there is a bad connection, will be at the sp-206 splice block that is on the left hand side of the bose amp location/ top left in the photo. Just pull it upwards to unclip it from the car, and you can check the bottom side of the block where the wires go in to see if you have a corrosion problem in the block. If problem is not there, then time to pull the BCM connectors to clean then, as well as check the connector to the radio that has the OG wire to it for the same


Number 1,


Look at bose amp, second screw line down on it, then to the left of it to see the glowing block that is clipped into the plastic part of the car.

Thanks! The car sat for a couple months hooked to tender. It has an aftermarket radio that has been in it, 5 years or so. I bought it prewired from a forum vendor.

Can the touch pad door releases be the issue?

I will try battery disconnect as well. If it isn’t either of the two items I just listed, should I then get a new aftermarket radio module?

thanks for your help!

No on the first,since if the BCM is opening the door, is getting the button signal to start with.

Yes on the second if the module hard reset with battery disconnect does not solve the problem, or may just see if the aftermarket radio module has a firmware update flash that may solve the problem isntead..

Thanks for your help! Disconnect the battery for 10 minutes and now everything is back to normal. The part I don’t understand, is that the windows did not need to be reindexed. They went down a little when I opened the door and back up when I closed them. I don’t recall that happening in the 17 years I have owned the car!

A, always use the battery cable disconnect from battery, touched to the two battery cables ends away from battery to each other, to quickly drain the modules power, then reconnect the batter as the first thing to do when Modules go funky.

As for if module goes completely power drained of not, its a time thing if you just disconnect the cables, verse once the cables are off, touch them to themselves away from the battery so you don't have to play the wait game to know that all the module caps have been power discharged as well.
So in your case since you did not touch the battery cables to each other once away from the battery once disconnector, sounds like the window modules did not go fully discharged with just the wait game, and why they did not need to be re-indexed.

Note I cheat, and just disconnect the positive cable from battery, and touch the positive free'd cable off to the negative cable still on the battery a couple of times to make sure that all the modules are fully discharged quickly, to speed up the module hard reset..
