Reduced Engine Power Mode

When the PCM detects a problem with the TAC system the PCM enters one of the following Reduced Engine Power Modes:

• Acceleration Limiting
  
  The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode
  
  The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode
  
  The control module will turn off the throttle actuator.
• Forced Idle Mode
  
  The control module will limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off, or; ignore the accelerator pedal input.
• Engine Shutdown Mode
  
  The control module will disable fuel and de-energize the throttle actuator.
