Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The DSA control module establishes communication with the engine control module (ECM) when the engine speed exceeds 600 rpm for the first time in the ignition cycle. This informs the engine control module (ECM) that there is a DSA system. The communication between the control modules is via cables for the load signal and the torque limiting signal. The engine control module (ECM) replies to the DSA control module with a special signal. Diagnostic trouble code (DTC) DSA-223 is stored within approximately 3 seconds if the DSA control module registers that the response is missing or deviates from the permitted value.
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 disappears (becomes intermittent) the diagnostic trouble code (DTC) will no longer be stored.

Substitute value
The DSA function is disengaged.

Possible source
- Fault in the engine management system.
- Intermittent open-circuit in the supply voltage or the ground lead for the DSA control module.

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