Code P0570

Has anybody dealt with this code before if so what is the fix?

It looks like the DTC is P057D not P0570. ("D" vs "0").

The possible causes listed on the autocodes.com website are: https://www.autocodes.com/p057d_chevrolet.html

Brake Pedal Position Sensor Calibration Faulty
Brake Pedal Position Sensor
Brake Pedal Position Sensor harness is open or shorted
Brake Pedal Position Sensor circuit poor electrical connection
Faulty Starter Generator Control Module

I don't know what year Caprice you have, but on my 2014 Caprice after I reprogrammed the body control module (BCM), I had to execute the BCM special function to get the brake pedal position relearned.

The P057C (the "low" voltage version of this DTC) has a similar list of potential sources. It could be as simple as a faulty brake pedal switch (position sensor) on the brake pedal.

From the parts charts, the 2014-2017 Caprices have a position sensor with GM part number 13597422.

The 2011-2013 Caprices use brake pedal position sensor GM part number 20995840.

Thanks for the info and your time. It’s a 2014 and did you post a video of how to execute the BCM special function process on your you tube channel?

He did Shawn, need the scanner capable of doing it but it's here:

Thanks Steve for posting the link to my BCM update video.

The relearn / scan tool steps start at the 24:09 time mark in the video. After updating the BCM, the DTC C0278-4B "Brake pedal position sensor - Calibration not learned" is present in the "Electronic brake control module" (ABS). I use the scan tool's special function access within the BCM to execute the "Brake pedal position sensor learn" function. It takes about 30 seconds to get into the special function and invoke the learn process. When I check the "Electronic brake control module" DTCs again, it still has the C0278-4B code, but now it's only a "history" code instead of an active code. I'm able to clear that DTC and the issue is resolved.
