What does PMF-A045 mean?
Tesla alert code in the Power Management Front (PMF) module. Pedal Monitor Warning: Motor movement detected during stationary excess heat The safety monitor sets this condition when rotor movement is detected during stationary excess heat production. Pedal Monitor Warning: Switch-off Path Test Failed. This condition is set when the power electronics and DI-PM switch-off path test fails, most likely due to damaged inverter hardware. Pedal Monitor Warning: Resolver operation abnormal. The safety monitor sets this condition when resolver speed or angle measurements in correspondence with DI are considered irrational or out of bounds.
