1.With the ignjtion switch OFF, disconnect the 5P con-
nector from the reminder unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
a lf the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector.- lf a test indicates a problem, find and correct
the cause, then recheck the system.
lf all the input tests prove OK, the remind€r unit
must be faulty; replace it.

Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-
trol unit.
2. lnspect the connector and socket terminals to be
sure they are all making good contact.
a It the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
a lf the terminals look OK, make the following in-
put tests at the connector.- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- lf all the input tests prove OK, substitute a
known-good control unit, and recheck the sys-
tem. lf the check is OK, the control unit must
be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the igni-
tion switch is turned ON (ll) and you step on the
brske Dedal (with the shift lever in E). the shift lock
system is electronically normal; if the shift lever
cannot be shifted from fl, test the 46 gear position
switch as described on page 23-142, and see sec-
tion 14.

1.Remove the console, then disconnect the 2P con-
nector of the shift lock solenoid trom the main wire
harness.
NOTE: Do not connect power to the B (- ) terminal
(reverse polarity) or you will damage the diode in-
side the solenoid.
Connect battery power to the A terminal, ground the
B terminal momentarily, and check solenoid
operation.
a lf the solenoid does not operate, replace it as
described in steps 3,4, and 5.
a lf the solenoid does operate, check and, i{ neces
sary, adjust its two positions as shown in step 5.
3. Remove the shift lock collar and the solenoid pin.
4. Remove the selfiocking nuts and shift lock solenoid,
then installthe new solenoid in the reverse order of
removal.

of the beeper circuit.
When the ignition key is not removed. the key-in reminder
in the integrated control unit senses ground through the
closed ignition key switch. When you open the driver's
door, the beeper circuit senses ground through the closed
door switch. With ground at the "LT BLU" and "GRN/

Engine Oil Pressure
Indicator System
Description
NOTE: Refer to page 23-152 for the circuit diagram ofthe engine oil pressure indicator flasher. and to page 23
156 for the input test of the flasher circuit.
The low engine oil pressure indicator light works in twoways. lt will flash continuously following a momentaryloss ol oil pressure, or it will go on and stay on wath a
complete loss of oil pressure.
When the engine first starts, before oil pressure rises
above 29.4 kPa (O.3 kgf/cmr, 4.3 psi), current flows
through the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
With the engine running, voltage is applied to the Ilash-er circuit of the integrated control unit. With normal oilpressure, the oil pressure switch is open and the low en-gine oil pressure indicator light does not operate. lf the
oil pressure switch closes momentarily (more than O.5
seconds). but then opens again, terminal "YEL/RED" will
sense ground through the switch- The integrated con-trol unit will then provide and remove ground tor the low
engine oil pressure indicator light through terminal"YEL/RED". The light will flash on and off untilthe igni
tion switch is turned to "OFF".
lf engine oil pressure talls below 29.4 kPa (O.3 kgf/cmr,
4.3 psi) and does not increase, the oil pressure switchwill stay closed. The low engine oil pressure indicator light
will go on and stay on.
NOTE: Refer to page 23-130 for the engine oil pressure
switch test.
