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.
Torque Interfaces
If torque reduction or increase is required for ASC/DSC/MSR/AGS, the ECM will regulate engine power in the following manner:
- If less torque is required, the ignition timing is reduced (fast intervention), the idle speed actuator and MDK/EDK reduce intake air.
- If increased torque is required (MSR), the idle speed actuator and MDK increase intake air.
The data required for engine torque manipulation is relayed via the CAN bus.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
