Check the relays, fuses & there connections. We also found the VSM wire connectors very corroded. I miratic acid cleaned all VSM terminals,plugs & die electriced everything.
Ours turned out to be the TVH cam sensor my tech installed from the beginning. Turns out he pushed in one of the terminals on the cam sensor.
I had 15 hours in it to find his screw up from the get go....
The flashing code doesn t just go away after it is repaired. Disconnecting the battery, & grounding the pos terminal did not work for me. I had to do the pedal dance to clear the dash flashing code..
