7 .7 Notes on controlling the stop lights
„
The stop lights must light up with every brake application in accordance
with legal requirements. This also applies for every brake application when
reversing.
„
The electronic control unit switches on the stop lights using the reverse light
power in accordance with the TÜV approval report.
„
Make sure that the power supply is adequately dimensioned and the
reversing lamp is secured as and additional feed for the stop lights.
„
If it is not possible to supply the stop lights via the reversing lamp, they can
also be supplied via terminal 15, for example. For this purpose, the TEBS E
Diagnostic Software option No stop light supply via reversing lamp (up to
Diagnosis V5.00) or Reversing signal input must be set to Reversing lamp
on GIO 14-3 (as of Diagnosis V5.10) and the reversing signal must be
connected via the connection GIO14, pin 3.
Stop light fault monitoring: If a fault monitoring system is installed for the stop
light, it may need to be adjusted. If the stop lights are monitored for faults: Fault
monitoring must only be active while the pedal is operated by the driver and
LED stop lights must not be installed. If necessary, the stop light fault monitoring
of the vehicle must be deactivated.
