Just purchased maxicheck pro to  bleed air from ABS module on 2002 chevy avalanche 1500 4wd. vin # is recognized but when trying to get to abs auto bleed, cannot get past request for 5th digit for VIN #. The letter "K" is not listed as an option and that IS the 5th digit on my VIN. What is the solution to this? I did an update already.
