The P0AFA code is usually triggered by a cell group in the main battery getting below 2.05V. There is a special programming process called in English "Clear Secured High-Voltage DTCs" after fixing any other DTC conditions that may exist. Once that programming step is run, the main battery will be re-enabled, and you have a functional car and the exciting challenge of never letting that weak cell group get below 2.05V ever again. (Mountain Mode instead of letting the battery run down to 0 miles, not shutting the car off while the engine is spinning and charging the battery, making sure to keep the battery charged whenever the car is just sitting will all help.)

What obd device will I need for this program. So do you have any idea for the other fault code?

I have no idea what P1FFF is referring to. It's not in my manual. From the picture showing and a little guessing, I think it's just telling you that the main contactor/relay will stay open/off until the P0AFA (the "secured high voltage DTC" in my earlier post) is cleared by the special programming process. You'll need either a GM MDI-2 (Multiple Diagnostic Interface) or a device that works like one (VCXNano for GM) and access to the programming tools (often through a subscription service like TIS2Web or GMSI). There are not-very-expensive subscriptions available for a single vehicle for a short period of time.

I don't know how to proceed with programming. Can you help me if I get the device?

Nope, never done it. There are several threads here that discuss it. One that's in my pile of bookmarks is VCX Nano help

Hello. I finally solved the problem in my car. I programmed the number 2 hybrid module with online tib coding and now my car is working. Thank you for your help.

What device did you use?
