DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION ECM-92CD
Condition
The diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects that the basic conditions for adaptation are not met when trying to adapt the electronic throttle unit. If other diagnostic trouble codes (DTCs) are stored, these must be remedied first. These may have caused the adaptation to fail.
Substitute Value
- The adaptation is cancelled
- The engine control module (ECM) shuts down the supply to the damper motor for the electronic throttle unit. The throttle will set itself to the return position.
Possible Source
Adaptation of the throttle unit is cancelled because one of the following basic requirements has not been met
- Ignition on / engine off
- The battery voltage must be over 10 V
- Accelerator pedal (AP) unaffected
- The vehicle must be stationary (no vehicle speed signal)
- Engine coolant temperature (ECT) between 5-100°C
- Intake air temperature (IAT) above 5 °C.
- The throttle is sticking or is blocked (e. g. oil film, dust)
- Contact resistance or oxidation in the terminals between the engine control module (ECM) and the electronic throttle unit
- Damaged throttle unit.
Fault symptom[s]
- Poor performance.
see DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION ECM-92CD
DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION ECM-92D0
Condition
The diagnostic trouble code (DTC) is stored if the ignition has been left on for 30 seconds and the engine control module (ECM) has been unable to adapt the electronic throttle unit. This is because the programmed parameter for the stop position in the throttle position (TP) sensor has been exceeded. Adaptation is usually carried out to ensure that the throttle unit parameters are within the programmed values that are stored in the engine control module (ECM). If other diagnostic trouble codes (DTCs) are stored, these must be remedied first. These may have caused the adaptation to fail.
Substitute Value
- The engine control module (ECM) uses parameters from previous successful adaptations
- The engine control module (ECM) shuts down the supply to the damper motor for the electronic throttle unit. The throttle will set itself to the return position.
Possible Source
- The throttle is sticking or is blocked (e. g. oil film, dust)
- Contact resistance or oxidation in the terminals between the engine control module (ECM) and the electronic throttle unit
- Damaged throttle unit.
Fault symptom[s]
- Poor performance.

Condition
The diagnostic trouble code (DTC) is stored if the engine control module (ECM), when attempting to adapt the electronic throttle unit, registers an internal fault in the integrated amplifier for the signal from potentiometer 1 in throttle position sensor (circuit 1) in the electronic throttle unit.

The engine control module (ECM) does not use the signal from potentiometer 1 for the throttle position (TP) sensor (circuit 1) in the electronic throttle unit.
Possible Source
- Damaged engine control module (ECM).
Fault symptom[s]
- None.
