Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
To check that the engine control system reacts as intended, the Engine control module (ECM) monitors continuously that requested torque from the engine does not become too high. To do this, the Engine control module (ECM) calculates a maximum allowed torque which is based on accelerator pedal angle and engine rpm. This torque is then compared with the requested torque. If Engine control module (ECM) registers that the requested torque exceeds the maximum allowed torque for longer time than 0.3 seconds, then diagnostic trouble code ECM-980A, Too high torque, is stored.
For upgraded software, released during year 2006 or later, this diagnostic trouble code is no longer necessary and therefore has been removed.

Substitute value
torque limiting

Possible source
- defective engine control module (ECM).

Fault symptom[s]
- none
