Remove the gauge assembly from the dashboard (see
page 23- l 1 8), and disconnect connectors "8", "C" and"D" from it. lnsoect the connecto. 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 input tests
at the connector.- lf any test indicates a problem, find and corect the
cause, then recheck the system.- lf all the input tests prove OK, the gauge assem-

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.

Adjustment
Belol€ adiusting lha hoadlights:
a Park the car on level ground.
a Make sure the luel tank is full.
a The driver or someone who weighs the same should
sit in the driver's seat.
a Load the trunk with the items you usually carry (if you
usually pull a trailer, attach it to the carl.
a Push down on the tront and rear bumDers several
times to make sure the car is sitting normally.
a When installing a new headlight assembly, tighten the
four mounting bolts so that.the indicator in the verti-
cal gauge comes to the "O" mark.
1. Open the hood.
2. Check that both the horizontal and vertical gauge
read " O" .
. lf the gauges rcad "O", check headlight aiming
with the aiming charts on page 23-163. (lf aim-
ing isn't correct, refer to the trame repair chart
in section 20.)
a lf one o. both gauges don't read "O". go to step
23-162
3. Turn the low beams on. lJ necessary, align the ver-
tical indicator with its "O" mark by turning the ver-
tical adiuster with a Phillips screwdriver, and check
aiming with the chart on page 23-163.
lf necessary, align the horizontal indicator with its"0" mark by turning the horizontal adjuster with a
Phillips screwdriver, and check aiming with the chart
on page 23-163.
4.
5.Recheck that the vertical indicator bubble is aligned
with "o" 1 1.
lf necsssary, adjust as described in step 3.
Turn the high beams on and check aiming with the
charts on page 23-163.
