Interlock System
Control Unit Input Test
Disconnect the 8-P connector from the control unit. Inspect the connector and socket terminals to be sure
they are all making good contact.
If the terminals are bent, loose, or corroded, repair
them as necessary, and recheck the system.
I
f
the terminals look OK, make the following input
tests at the connector .
– If a test indicates a problem, find and correct the cause, then recheck the system.
– If all the input tests prove OK, the control unit must be faulty; replace it.
NOTE: If the shift lock solenoid clicks when you step
on the brake pedal with the ignition switch ON (the
Shift lever in position), the shift lock system is
electronically OK. If the shift lever cannot be shift-
ed from position, see page 23-160 ('93-'96)
('91-'92) and section 14
.

Lights-on Reminder Systen.
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
