Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




Diagnostic trouble code (DTC) ECM-917F is stored if the engine control module (ECM) registers, with the ignition on, the parameters for the throttle unit do not correspond to the previous adaptation and that one of the basic conditions for adaptation has not been met.

Substitute value
The engine control module (ECM) limits the torque using the fuel shut-off system.

Possible source

Faulty signal:
Adaptation of the throttle unit is cancelled because one of the following basic requirements has not been met:
1. Ignition on / engine off
2. The battery voltage must be over 10 V
3. Accelerator pedal (AP) unaffected
4. The car must be stationary (no vehicle speed signal)
5. Engine coolant temperature (ECT) between 5-100 °C
6. Intake air temperature (IAT) above 5 °C.
- The throttle is sticking or is blocked (oil film, dust etc.)
- Contact resistance or oxidation in the terminals between the engine control module (ECM) and the throttle unit
- Defective throttle unit.

Fault symptom[s]
- Poor performance.
