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.
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.
