Diagnostic trouble code (DTC) information

Condition 

Fig 1: Identifying DSA Control Module And Engine Control Module (ECM)

When the DSA control module registers that the speed at one of the front wheels increases too much (spins), the DSA control module transmits a signal requesting torque limiting to the engine control module (ECM). Diagnostic trouble code (DTC) DSA-131 is stored if the DSA control module registers that the current in the circuit for the engine control module (ECM) is too large or too small with the engine running.

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.
