Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The throttle position (TP) sensor signal from the engine control module (ECM) is a pulsed signal (between approximately 0 V and battery voltage) with a fixed frequency (approximately 50 Hz). The pulse ratio (% duty) changes as the throttle opens. Diagnostic trouble code (DTC) DSA-231 is stored if the DSA control module registers that that there are no pulses from the engine control module (ECM) for approximately 0.5 seconds.

Substitute value
The DSA function is disengaged.

Possible source
- Open-circuit in the signal cable.
- Short-circuit to supply voltage or ground in the signal cable.
- Contact resistance in the terminals.

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