Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-910E

Condition




The electronic throttle module (ETM) performs a number of internal tests to check that the processor, software and memory are operating properly. If any of these tests register a fault, this information is sent to the engine control module (ECM), which stores diagnostic trouble code ECM-910E.

Substitute value

Fuel cut-off that follows accelerator pedal position.
Engine speed is regulated via fuel cut-off by deactivating the injectors one at a time. Engine speed is determined by gas pedal position sensor position and engine speed is maximized to about 5000 rpm.
This reconfiguration can cause the engine to idle very unevenly since the engine control module (ECM) regulates engine speed by cutting of the fuel to the cylinders individually. Do not confuse this reconfiguration (engine behavior) with an actual driveability problem that was present before reconfiguration.

Closing of throttle during braking.
The accelerator pedal position is ignored when the brake pedal is depressed.

Cruise control off.
Cruise control off during entire operating cycle in which fault was detected. If the fault is no longer present, the function is available the next time the car is started.
When the fault is detected repeatedly in the same driving cycle, the following also occurs:
The electronic throttle module (ETC.) deactivates the throttle motor control, which means that the throttle is not actuated and assumes its mechanical stop position. This means about 20% throttle opening.
For upgraded software, released in 2006 or later, adjustments have been made to substitute values. In driving cycles when the fault is active, fuel shut-off that follows the accelerator pedal position will be activated.

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
- ETS warning lamp lit.
