Customer request:
My late 2012 Opel Ampera has the dreaded SVHC error. Checked battery coolant & sensor as all advise. My usual OBDII resets for .5 second. Now unable to charge from charge port. Battery does buil up via Mountain mode.
I purchased the VXDiag VCX FD. Do I need GM Techline Connect or PSA Service box to program module HPCM2? I have PSA account now & purchased both a diagnostic package & the software download credit. But unsure exactly which software & sequence to follow.
Here is the clue.
Many users have managed to use the Service Box system to re-program their Ampera to remove the SHVC warnin.
What you need:
VXDIAG VCX FD or VXDIAG VCX NANO with GM license
PSA Service Box online account (2hr SPS subscription for 54 euro.)

A token is required to access the software download. A token allows you to use the manufacturer’s electronic diagnostic and repair tool and to consult the diagnostic ranges on a vehicle (1 VIN number) for one week.
Example: 1 vehicle for 2 weeks = 2 vehicles for 1 week = 2 tokens.
