Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




If a fault has occurred in the engine management system which affects the fuel shut-off system, the engine control module (ECM) transmits a load signal (TQ) with a specific value to the DSA control module. Diagnostic trouble code (DTC) DSA-224 is stored when the DSA control module has received this specific signal.
Note!The diagnostic trouble code (DTC) is only stored as long as the ignition is on / the engine is running and the fault is permanent. If the fault in the engine management system disappears (the fault becomes intermittent) the diagnostic trouble code (DTC) will no longer be stored in the DSA control module.

Substitute value
The DSA function is disengaged.

Possible source
- One or more diagnostic trouble codes (DTCs) has been stored in the engine control module (ECM)
- Intermittent open-circuit in the supply voltage or the ground terminals for the engine control module (ECM).

Fault symptom[s]
- The DSA warning lamp lights
- The anti-spin function is not operative while the DSA function is disengaged.
