Description

Reason:
Engine Torque Limit Feature – Special Instructions

Effect:
None on performance

Circuit Description:
This is an information only fault that will only become active if the engine has been operated above a calibrated torque threshold.

Component Location:
The ECM mounting location varies, depending on the engine model, and may be mounted either on or off the engine.

Conditions for Running the Diagnostics:
This diagnostic runs continuously when the engine is running.

Conditions for Setting the Fault Codes:
The Engine Control Module (ECM) detected the engine was being operated above the maximum torque threshold.
