Key-in Reminder System
lgnition Key Switch Test
NOTE: Refer to page 23-145fot a diagram of the key-
in leminder circuit, and to page 23-148 Jor the input test
ol 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/
BLU" terminals, the beeper sounds.
1 . Remove the dashboard lower cover and knee bolster
(see page 23-70).
2. Disconnect the 7-P connector from the main wire
harness.
Check for continuity between the No. 2 and No. 4
terminals in each condition acco.ding to the table.
l.
Door Switch Test
Open the door.
Remove the screw, then pull out the door switch.
Disconnect the 1-P connector from the switch.
4. Check lor continuity between the positive terminal
and the base plate (ground) in each switch position
according to the table.

Engine Oil Pressure
Indicator System
Description
NOTE: Reter to page 23-144 tor the circuit diagram otthe engine oil pressure indicator flasher, snd to page
23-148 lor the input test of the flasher circuit.
The low engine oil pressure indicator tight works in twoways. lt will flash continuously following a momentaryloss of oil pressure, or it will go on and stay on with acomplete loss of oil pressure.
When the engine first starts, before oil Dressure risesabove 29.4 kP8 10.3 kgf/cmr, 4.3 psi), current flowsthrough the low engine oil pressure indicator light andthe oil pressure switch to ground. This tests the circuit.
Wilh the engine running, voltage is applied ro the ftash-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 theoil pressure switch closes momentarily (more than O.5secondsl, but then opens again, terminal "yEL/RED,'will
sense ground through the switch. The integrated con-trol unit willthen provide and remove ground for th€ lowengine oil pressure indicator light through terminal"YEL/RED". The light will flash on and olf until the igni-tion switch is turned to "OFF".
lf engine oil pressure falls below 29.4 kPa (O.3 kgJ/cmr,4.3 psi) and does not increase, the oil pressure switchwillstsy closed. The low engine oilpressure indicator lightwill go on and stav on.
NOTE; Refer to page 23-122lot the engine oil pressure
switch test.
Lights-on Reminder
System
Description
Chime Test
Remove the dashboard lower cover and knee bolster
{see page 23-70).
Disconnect the 2-P connector t.om the dashboardwire hamess.
Test the chime by connecting battery power to the"A" te.minal and ground to the "B" terminal, andcycling the power on-off repestedly.
lf the chime fails to sound every time power is cy-cled, reDlace it.
NOTE: Refer to page 23-145 tor a diagram of the lights-
on reminder circuit, and to page 23-149 for the input
tests of the circuit.
When the ignition key is turned to OFF 8nd removed. withthe lights on, voltage is apptied to the reminder circuitin the integrat€d control unit. When you open the driver,sdoor, the circuit senses ground through the closed doorswitch.
With voltage at the "H" terminal, ground at the"GRN/BLU2" terminal and no voltage at the ,,F,' termi-nal, the chime sounds to remind the driver to turn oJf thelights.
