Diagnostic trouble code (DTC) information
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Condition
The DSA control module terminal is grounded via the stop lamp bulbs when the stop lamp switch is unaffected. The DSA control module (and bulbs) are supplied with battery voltage when the stop light switch is activated. Diagnostic trouble code (DTC) DSA-212 is stored if the DSA control module registers, when the engine is running, that there is no ground connection via the bulbs, or that the signal (voltage) during braking is lower than battery voltage as a result of a drop in the voltage supply.
Substitute Value
The DSA function is disengaged.
Possible Source
- Open-circuit in the signal cable
- Contact resistance in the terminals
- Voltage drop in the power supply.
Fault symptom[s]
- The DSA warning lamp lights
- The anti-spin function is not operative while the DSA function is disengaged.
