As far as I know this truck has never had high speed lift. The M3 motor looks like new. If you ground the P2 contactor the motor and pump will run. No ground found when backprobing the Access2. The values for the lift handle are good. The P2 is turned on in the settings but output tests are not available. I've tried another Access2. I thought there might some safety issue but no warnings or codes appear.
