DTC ECM-910E

Condition







The electronic throttle module has registered an internal fault. Diagnostic trouble code (DTC) ECM-910E is stored in the engine control module (ECM).

Substitute value
- the accelerator pedal (AP) is ignored when braking
- the cruise control cannot be activated
- the engine speed (RPM) is limited using fuel shut off. The maximum permitted engine speed depends on the accelerator pedal (AP) position
- if the fault is detected repeatedly during the same operating cycle, the throttle unit switches to the mechanical limp-home mode and the throttle disc moves to the fixed position.

Possible source
- defective throttle unit.

Fault symptom[s]
- the accelerator pedal (AP) is ignored when braking
- the cruise control cannot be activated
- uneven idle
- jerks during engine braking
- extremely poor throttle response, if the fault is detected repeatedly during the same operating cycle
- the maximum speed is approximately 50 km/h if the fault is detected repeatedly during the same operating cycle.
