Maintenance Reminder Unit Input Test
1.With the ignition switch OFF, disconnect the 5-P
connector from the reminder unit,
Inspect the connector and socket terminals to be
sufe they are all making good contact.
a lJ the terminals are bent, loose orcorroded, repair
them as necessary, and recheck the svstem.
a It the terminals look OK, make the following in-
Put tests at the connecto..- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- It allthe input tests prove OK, the reminder unit
must be taulty; replace it.

Control Unit Input Test
Oisconnect the 8-P connector from the interlock control
unit. Check for good contact between the connector and
socket terminals. lf the terminals 8re OK, make Iollow-
ing input tests at the connector. lf all input tests are OK,
but the problem remains, replace the cont.ol unit,
NOTE: lf the shilt lock solenoid clicks when the ignition
switch is ON and the brake pedal is pushed (shift tever
is in lfl position, accelerator is in rest position), the shiftlock system is electronically normal; test the A/T gear

1. Remove the instrument panel lrom the dsshboard
{see page 23-1181.
2. Remove the dash lights b.ightness controller {rom
the dashboard. then disconnect the 3-P connector.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent. loose o. corroded, repsir
them as necessary, and recheck the system.
a It the terminals look OK, make the tollowing in-
Dut tests at the connector.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the dash lights
brightness controller must be faulty; replace it.
