3309190 - E2021 BRAKE LIGHTS - Description (Right hand drive)
Description
The brake lights are located at the rear
in the side lights and in the central third brake light and consist
of 10 separate bulbs.These are operated whenever the brake pedal
is pressed, by means of a switch on the pedal itself.Operation of both side brake lights is monitored
by the exterior lighting check device.The following faults may occur:
- blown bulb
- bulb s.c. to earth or positive
- incorrect bulb (5W bulb instead of 21W)
A special light failure warning light comes
on on the dashboard for all anomalies in the various circuits. This
warning light comes on for about 6 seconds when the ignition key is
turned to MAR, to indicate it is working properly, then it goes
off.The circuit is protected by the two fuses
protecting lights monitored by the check function.A braking signal is also sent from the switch
to the ABS, which detects braking status and therefore introduces
braking control. The same signal is also sent to some engine management
systems, which take the braking condition into account when determining
the engine control mode.
