A diagnostically understandable description of the Diagnostic Trouble Code

Mazda B2A33

Basic error definition

Stop (brake) Lamp Switch. Signal Too High

Cause of DTC

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. 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.
