Fix Opel Ampera 2012 P1FFF Error Using VXDIAG & Service Box

Having a latched HPCM2 P1FFF fault code with Opel Ampera 2012. This common issue is often related to battery aging but can sometimes be resolved through module reprogramming.

 

Understanding the P1FFF Error

The P1FFF code in the Opel Ampera typically indicates:

• Hybrid battery degradation (most common cause).
• Voltage imbalance between battery cells.
• Software needing an update (K114B & K16 modules).

Since my car had no physical battery issues, I suspected a software/firmware problem and decided to reprogram the modules.

 

Device used:

Bought a VXDIAG VCX NANO GM scanner.

I bought a cheap refurbished Windows 10 laptop for it.

You can download the software from their website: VXDIAG Diagnostic Software Download
You want VXDIAG GM 2024.05.08.
You need to turn off anti-virus and windows defender before you expand the zip files, otherwise one of the files gets deleted.
You can install it before buying the VCX Nano, though you do need it a one point to complete the setup – read the instructions earlier in their blogs.
Vxdiagshop.com can help if you have problems once you’ve bought the VCX Nano – they helped me with an online session using remote access.

 

 

I paid and installed Techline Connect and tried to do the programming there, but no luck. Maybe it was possible before Opel was sold to Stellantis.

 

UPDATED:

I created Stellantis account lately to access Servicebox.
Update on my P1FFF situation.
In bit under week Stellantis verified my account. I used my own company’s details to sign up. The company does not have anything to do with cars. So I don’t know how they are checking validity of the provided information.
Vat number needs to be in correct format. (even tho it is not correct VAT number).
I updated the K114B and K16 modules, and now everything works as expected.
K16 module programming takes almost 10 minutes when the programming is at 100%, so be patient don’t unplug your VXDIAG J2345 before it is done as I did at the fist time.

They charged me 64€ for two hour permission to use SPS. The site itself stated that SPS costs 54€ for 2 hours.
