We have a customer that’s been to the stealership after jump staring his car causing poor running, they reprogrammed the calibration only and it keeps throwing PO601 (ECM Flash Eeprom checksum error) the car runs but cuts out around 40mph and goes into reduced power mode.
would doing a full reflash possibly help or is the ECM dead, don’t really wont to waste a license if its got no chance of fixing the fault, but would like to try as a new computer is $1800 here. Thanks.
