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 (brake) lamp bulbs when the stop (brake) lamp switch is not activated. The DSA control module (and bulbs) are supplied with battery voltage supply when the stop (brake) light switch is activated. If the vehicle speed is in excess of 50 km/h and the DSA control module registers that the signal is too high (high voltage) continuously for 15 minutes, the DSA control module interprets it as being outside the permitted range. Diagnostic trouble code (DTC) DSA-211 is stored.
Substitute Value
The DSA function is disengaged.
NOTE:
This fault is considered to be serious. If the status of the fault changes to intermittent, the DSA function will not be engaged until the diagnostic trouble code (DTC) has been erased.
Possible Source
- Open-circuit in the signal cable
- Short-circuit to supply voltage in the signal cable
- Incorrectly adjusted stop (brake) lamp switch
- Defective stop (brake) light switch.
Fault symptom[s]
- The DSA warning lamp lights
- The anti-spin function is not operative while the DSA function is disengaged.
