If the control module for traction control detects that the stop-light switch has been activated for longer than 60 seconds, but at the same time braking appears illogical, this fault is set. Simultaneous operation of the accelerator pedal module, for example, is an argument against braking.
If the fault is currently not present, there is no change in status when the stop-light switch is actuated, i.e. the success of the repair can be seen from the renewed change in status of the stop-light switch. The change in status can be read out via the diagnosis requests.
