. Description
Safety Indicator System:
LED's are used to indicate when the turnk lid or a door is not fully closed, or when a brake light is faulty. the LED's
will remain ON for about 2 seconds after the ignition switch has been turned ON to show that the system circuit is fun-
citoning.
Brake Light Bulb Failure Indicator:
If all brake light bulbs are OK, the Indicator light stays off because the ORNANHT wire is constantly being grounded
by the two brake light failure sensors connected in series. With the brake light off, the ground is provided through the
diode, the failure sensor relay coil and bulb filaments to ground. With the brake light on, all 4 relays, (2 in the left sensor,
2 in the right sensor) connected in series, supply ground. If any of the 4 bulbs is not working, the chain is broken and
the ORNiWHT wire is not being grounded. The Indicator light comes on.
