Description
Safety Indicator System: LED's are used to indicate when the trunk lid, engine compartment lid, a door, or the roof is not latched, or when a brake
light is faulty, or when the roof is not stored or improperly stored in its holder. The LED's will go on and stay on for about
two seconds after the ignition switch has been turned ON, to show that the system circuit is functioning.
Brake Light Bulb Failure Indicator:
If all brake light bulbs are OK, the indicator light stays off because the ORN/WHT wire is grounded by the two brake light
failure sensors connected in series. With the brake lights off, the ground is provided through the diode, the failure sensor relay coil, and bulb filaments. With the brake light on, all four relays (two in the left sensor, two in the right sensor), con-
nected in series, supply ground. If any of the four bulbs is not working, the chain is broken and the ORN/WHT wire is not
longer grounded. The indicator light comes on.ProCarManuals.com

Chime Test
NOTE: Refer to page 23-158 ('93-'96) ('91-'92) for a dia-
gram of the lights-o
n
reminder circuit, and page 23-166
for the input test of the circuit.
When the ignition key is turned off and removed with
the lights on, voltage is applied to the reminder circuit in
the integrated control unit. When you open the driver's
door, the circuit senses ground through the closed door
switch. With voltage at the "A6" terminal, ground at the "GRN/BLU 2
" terminal, and no voltage at the "A5" termi-
nal, the chime sounds to remind the driver to turn off
the lights.
1. Remove the dashboard lower cover, and disconnect the connectors.

2. Test the chime by connecting battery power to the "B" terminal, and ground to the "A" terminal, and
cycling the power on-off repeatedly.
3. If the chime fails to sound every time power is cycled, replace it.ProCarManuals.com
