1. Principle of turn signal lamp control
The turn signal lamp control is divided into three categories while the final control is
implemented by the flasher relay.
Alarm switch control: The alarm switch has the power supply from the battery F7 fuse. So, it
ensures that the switch can work in case that the ignition switch doesn
’
t turn on. When the alarm
switch is in ON position, the flasher relay is powered by the terminals 5# and 6# of the alarm
switch. In this case, the emitter electrode of the relay will provide a intermittent voltage signal,
and the terminals 1#, 2# and 3# of two alarm switches utilize this intermittent signal to turn on the
turn signal lamp and make the turn signal lamp work.
Turn signal lamp control: When the alarm switch is out of service, the electric power of
flasher relay base electrode is supplied from the terminal F16 of the ignition switch. In case that
the turn signal lamp switch turns on the left or right circuit, the intermittent power supply from
flasher relay will enable the corresponding turn signal lamp to work. So, the turn signal lamp
control is just the direct switch control.
BCM control: For the sake of body anti-theft requirement, the turn signal lamp is required to
work when remote control of arming and the elimination of anti-theft. So, BCM also controls the
turn signal lamp. This control is not via the alarm and turn signal switches, and its intermittent
signal is implemented with its internal circuit.
