Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Emergency Operation 2
If another fault is encountered in addition to emergency operation 1 or if the plausibility is affected, emergency operation 2 is activated by the ECM. An example of plausibility fault would be that the pulley position does not match the MDK position and the associated airflow (from the HFM). Emergency operation 2 can also be initiated by simultaneously pressing both the accelerator pedal and the brake pedal, or if a fault is encountered in the brake light switch diagnosis (see PERFORMANCE CONTROLS ).
When in emergency 2 operation mode, there is an engine speed limitation (slightly above idle speed) in addition to the measures for emergency operation 1. In emergency operation 2, the engine speed is always limited to 1300 RPM if the brake is not applied, and approximately 1000 RPM if the brake is applied. The vehicle speed is limited to approximately 20-25 mph.
The emergency operation functions are inactive when:
- Emergency operation 1 - Faults which affect the functioning of the MDK.
- Emergency operation 2 - Applies when faults are encountered which might affect driveability.
- Emergency operation of Idle Air Actuator.
