Model sbc007. Is there a function to allow the radio to turn itself off after a set period eg 15min, 30 min etc.?

try owners manual some vehicles have courtesy accessories on for a timed period and will turn off after you open the door and have removed the key eg. 2005 tahoe will play the radio after turning off the ignition for ten or fifteen minutes

Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one

need some more information to help with that.
Itself off means
- It completely goes off
or
- light stays on and no sound
and
- can u switch on it back by pressing power button
thanks.

The drive cycle is a series of conditions that you drive a vehicle to prepare the emissions systems for an emmisions test.

the drive cycle that is most common to GM vehicles is the following;

1. cold start vehicle and allow to warm up to driving temperature, then set a load on the engine, ie. turn on radio and A/C MAX and headlights.
2. reverse vehicle for approx. 15-20 ft.
3. from a stop, drive vehicle at 35mph @ 25% throttle for 15min
4. allow vehicle to slow to a near stop without using hte brake pedal.
5, begin driving vehivle again 45mph @ 50% throttle for 15-20 min.
6. check for emissions status and test.

***OBDII vehicles (95-99) can have up to (2) two emissions monitors at unready status for PA and can sucessfully submit a "pass" status.
vehicles that are 1988 (OBDI) are emissions exempt.

As a security measure, any time the battery is disconnected, the radio is Locked Out, and will not function until the security code is entered on the radio itself. Furthermore, after 3 tries, it wont even accept the code on the radio display, showing the ERR condition. Check for a sticker with the radio code inside the glove box. Some dealers fixed a second sticker in the owners manual. If not available, get the code from a Honda dealer, and be prepared to show VIN number, and proof of vehicle ownership.When you get hold of the code, disconnect the battery for 15 min. This will erase the ERR condition, and allow you to introduce the reactivation code.

Give me some more information about this problem. May be i can help.

Without knowing which radio you have??? I will guess. With the radio OFF, push the SET button, now use the Seek/Scan buttons to change the time. when done, push the set button again.

the radio is in theft lock, you will need your unique code that came with the truck new to unlock it.

Usually disconnecting the battery for anywhere from 10 - 30 mins resets any codes stored in memory.

Sometimes however it is a specific amount of "key cycling" that is required. eg: Turn key on, then off, then on for X seconds, then off for X seconds, then start engine etc. etc. etc.

If you have disconnected the battery, and there are no codes present but the light still comes on, there could be an issue with your airbag system. Wiring, or something was not done right.

WARNING : If you intend to work on the airbag yourself remember to disconnect battery for at least 45 mins. The air bag requires approx. 20-60 mins (depending on the vehicle, make and model and year) to discharge. If you do not do this you risk deploying the air bag, and that could ****!
