Bypassed TheftLock on GM Chevy Class II MP3 CD HU

[playtoy_18]

If you mean me,than no I don't know the code.
The vehicle had BCM issues triggering the passkey,I programmed out the passkey. After restarting the radio randomly locked itself and have not been able to reset.
I am showing faults on the class 2 data link across 4-5 modules,so i'm pretty sure the radio is simply getting a corrupted vin signal.
I would rather figure out what is wrong,but this is a $600 car and they don't wanna pay for M-time diag or a dealer reprogram.

So I told them to let me try this eprom removal as a nuclear option before installing something aftermarket.

I do not have a techII,only a tech1-and it won't touch the bcm.
Still saving for an MDI.

I have a 6 disc CD changer from a salvage yard. Its Gm part # is 15234915, Delphi part # 21002195, manufactured date 10/19/05. I am putting it in a 2004 gmc sierra 1500 wt 4x4. It came out of a 2006 Chevrolet 2500 wt. Has the exact same wiring harness as my gmc.I took the chip out as I have read to do and I have seen on YouTube. Everything comes on like it should. Retains clock, settings, etc... Shows CAL ERR when cut it on, but and everything works. Except, it has no volume and wont play. If I hit the search button it just keeps searching. Any suggestions?

Thanks.

Hello all, I am in this fight with all of you. I have successfully obtained a dump from the eeprom that gives us all this trouble. However, I do not have any knowledge on what needs modified. Any one that can help???? I have attached a copy of the dump from the eeprom. Would love some help!!!! You will need to unzip it first.

I just did something similiar, I just removed the chip. Same result, it says it is initializing and shows the cassette tape icon which I don't have. The radio had a date of 2001 and I put it into my 2007 Chevy Express. This radio/CD has better reception and sound than the stock radio that was in it. Plus my tuner dial didn't work well anymore.
If you want a quick way to get the radio to work temporarily, you can (key turned off) press and hold (seek>) and the (5) channel button together and then at the same time hold the power button on. All 3 buttons at the same time. This should turn the radio on, then start your vehicle. The radio should work, the CD may work, the station buttons may not and you may not be able to switch AM/FM/CD. Once you shut off the ignition you will have to start the process over again.

has anyone succesfully done this with GM part 10357886? AM/FM/6CD from 2003/2004s?

keep seeing only the AM/FM/CD or AM/Fm/CD/Tape versions.

I have an 04 colorado and got that part from another 04 colorado and would rather not pay 100 bucks for the dealer to tell me they couldn't program it as all dealers pretty much just blanket say "it may not work" which to me means "It won't or we won't really try"

Ok.

I got it to work with my 2004 6 disc from a colorado.

removed PIN 8, all is well.

photos and stuff.

Hi,
I have replaced my original UB1 stereo cassette (pn 15198701) with a 6 CD UB6 (pn 15185935) both RDS; in myu 2003 1500 Silverado. I removed the eeprom completely and all works
except no memory on am/fm presets.
Any help would be appreciated to get memory back to presets.
I read here that one guy had an eeprom installed and programmed by AJR International for all GM; and there is no direct link on the web related to automotive eeproms. I cannot find the correct AJR International?

I did work on spare radio pn 10359566 (no RDS on front) and disconnected pin 8 only (pwr) and no sound; removed eeprom completely and
not pwr to unit.

Thanks. any help for memory presets appreciated.

The Vin is stored in the last line of the Eprom chip. Just the last 6 digits. With an editor you can change to the last 6 on your car re-flash the chip and reinstall.

Does anyone know if this procedure would work on a 2001 Silverado 15766343 radio, single CD driver? This original radio, unmodified in any manner doesn't work, the lights come on but the display screen on the upper right is blank. It seems to have stopped working a year ago when a new BCM (Body Computer Module) was put in the vehicle to fix a 0.6 amp battery drain. The mechanic who put in the BCM says he doubts if radio was Vin locked going back that far in time. Should I take it apart and look for a removed EEPROM 24C08B chip or a chip with leg 8 cut?

[VonoreTn]

I have the radio apart now, here are some photos. Is the eeprom close enough based on only being one digit different from the initial instructions on this topic?

So I have the 6 disc changer, and the original radio went out. I got an exact replacement for it from a local salvage yard. I tested it first and it powered on and did say locked, I opened up the casing located the eeprom chip, and removed it. Plugged back into Tahoe and now nothing it won't even power on. Any ideas or help would be appreviated.

Hello, New to the forum. I have read More than a few posts about disabling the eprom to bypass the TheftLock that GM was so nice to give us. I am working with a "04-05 Pontiac Grand Am Sunfire Monsoon Radio AMFM CD GM Part No. 22724376" My Hope is to install it into an 04 Pontiac Vibe. I have read of several different results in doing this, by either lifting pin 8, and by removing the ic all together.
Has anyone done THIS radio, and if so, what are the results for each of the options.
Of course the lcd display lights are burned out on Both the Vibe OEM radio, and the New MP3 radio I would like to use. It is my intention to upgrade the bulbs with 12v led bulbs. If and when I get this to fly, I will pass along any results to the form. Thanks

I have never heard of that......basically, it's not the Theftlock that is the problem, it's the VIN # that is programmed into the radio.....if it doesn't match the VIN of the car, then there are communication problems....

As for the LED's, they don't usually burnout, they last forever.....it's the circuit board that feeds them that is the problem.....sometimes it's just a soldered joint, sometimes it's the board itself....
