SUPERCHARGER SYSTEM OVERBOOST
Normally PCM commands Boost Control (BC) solenoid to operate
at 100 percent (ON) Pulse Width Modulation (PWM) to allow for full
intake boost upon demand. If Reverse is selected, PCM detects rapid
deceleration, or engine is load is extremely high, PCM commands BC
solenoid to operate at zero percent (OFF) PWM.
You likely won't notice any drivability problems.
- Engine torque exceeds maximum predetermined torque threshold
