Safsiy lndicator Systsm:
Bulbs are used to indicate when the trunk lid or a door is not fully closed, or when a brake light is faulty. The bulbs will re-
main ON Jor about two seconds after the ignition switch has been turned ON to show that the system circuit is
functioning.
Blako Light Bulb Fallule Indicatot:
lf all brake light bulbs are OK, the indicator light stays off because the WHT/GRN wire is constantly being grounded by
the two brake light tailure sensors connected in series. With the brake light ott, the ground is provided through the diode,
the failure sensor relay coil, and the bulb filaments. With the brake light on, alltour relays (three in the leit sensor. one in
the right sensor), connected in series, supply ground. lJ either of the two bulbs is not working. the chain is broken and the
WHT/GRN wire is not being grounded. The indicator light comes on.
