Help...

[defyrfytr]

I have a 04 GMC K1500 with the 5.3l motor. The truck has approx. 17,000 miles. I just installed a k&n fipk and a hypertech chip. When I installed the chip, it scanned and up came the B1000 code. I cleared the code and programmed the chip and the code returned. I am not sure what the code is. Any help would be appreciated.

 

Thanks.....

According to my book for the 2003 GMC Sierra, DTC B1000 is defined as the following:

 

Conditions for Running the DTC

The module (see below) runs the program to detect an internal fault when power up is commanded. The only requirements are voltage and ground. This program runs even if the voltage is out of the valid operating range.

 

Conditions for Setting the DTC

The module has detected and internal malfunction.

 

Action Taken When the DTC Sets

The module refuses all additional inputs.

 

Diagnostic Aids

If the DTC is set as a history DTC only, do not replace the module.

If the DTC is retreived as both a history and current DTC, replace the module.

 

Modules:

Audio Amplifier, BCM, DDM, DRR, FPDM, HVAC, IPC, MSM-Driver, Radio, RWSCM, SDM, VCIM.

 

Edit - Basically if the DTC ID didn't change between 03 and 04, you're going to need to talk to the dealer. Since you're under warranty it should be no issue. Not sure about mentioning the Hypertech chip, but their Tech 2 will see the code and it can find the module at fault.

Jim,

 

Thanks, that reminds me... The truck was bought used and the cd had a disc stuck in it. The radio was replaced by the dealer and they told me they had a code that they did not know how to get rid of. The dealer told me to bring it back but I never found the time. Thanks for reminding me to call the dealer to get the truck back in.....

They [the dealer] don't know how to get rid of the code?

According to the book, they can't. Once the malfunctioning module is replaced, the DTC is a history code. It will be cleared when the ignition cycle counter reaches the reset threshold and the malfunction is not repeated during that time. That's paraphrased from the service manual.

 

Well, good luck with it. If your radio is still working I'd doubt that's the current cause of the issue. According to the service manual the faulted module won't operate.

When the dealer installed the new radio, everything works fine. When the radio is powered up, an error message appears for a couple of seconds. The message never comes on again until the truck is restarted. The dealers "radio specialist" was not in when the install was done. They said they would call the manufacturer for more info. The radio, cd and everything works fine. I noticed the code only after programming the chip. The hypertech programmer read the code but could not reset it. I don't really think this will be a major problem.

Thanks for the reply....
