1. REMOVE INNER PANEL SIDE GARNISH
Before making adjustments, remove the inner panel side
garnish.
HINT: After adjustment, reinstall the inner panel side gar-
nish.
2. TO ADJUST LEVEL DIFFERENCE
Adjust by increasing or decreasing the number of shims.
HINT: If the front of the sliding roof is high, even without a
shoe shim, chek to see if the front shoes are in contact with
the stoppers.
3. TO ADJUST FORWARD OR REARWARD

Current is led from the battery to terminal 12 of the running light relay.
Operation examples of the switch are shown below.
1. IGNITION SWITCH ºONº AND LIGHT CONTROL SWITCH ºOFFº
When the switches are set, current is led from the battery to terminal 1 of the running light relay. Also,
because continuity is made between terminal 3 and the body ground, and 5 and the body ground of
the running light relay, the taillight control relay and headlight control relay are turned on.
Then the taillights and headlights light up.
HINT: Because terminal 14 of the running light relay is not grounded at all times, the headlight dimmer
relay is off, so that the headlights light up at the low beam.
2. LIGHT CONTROL SWITCH IN ºHEADº
When the switch is set, continuity is made between terminal 4 and the body ground, and 2 and the body
ground of the running light relay. Also, because the continuity is made between terminal 5 and the body
ground, and 3 and the body ground of the running light relay at all times, the taillights and headlights
light up.
HINT: When the headlight dimmer switch is set to ºHIGHº, continuity is made between terminal 13 of
the running light relay and the body ground. Also, because continuity is made between terminal 14 of
the running light relay and the body ground, the headlight dimmer relay is turned on. Then the head-
lights go on at the high beam.
3. HEADLIGHT DIMMER SWITCH IN ºFLASHº
When the switch is set, continuity is made between terminal 6 and the body ground, and 13 and the
body ground of the running light relay. Also, because the continuity is made between terminal 5 and
the body ground, and 14 and the body ground of the running light relay, the headlights flash.
4. ENGINE STOPS (IGNITION SWITCH ºONº)
When the engine is stopped, because the continuity between terminal 5 and terminal 10 of the running
light relay remains, so the running lights also remain.
HINT: If ignition switch is turned to ºOFFº, running lights will go off because the continuity between termi-
nal 5 and terminal 10 of the running light relay is cut off.
Light Control Rheostat
INSPECTION OF RHEOSTAT
INSPECT RHEOSTAT OPERATION
(a) Connect the positive (+) lead from the battery to
terminal 1 and the negative (±) lead to terminal 2.
(b) Connect the terminals 1 and 3 through a 3.4 W test bulb.
(c) Gradually turn the rheostat knob from the bright side to
dark side, check that the test bulb brightness changes
from bright to dark.
If operation is not as specified, replace the rheostat.

(Relay Operation)
(a) Connect the positive (+) lead from the voltmeter to ter-
minal 7 and negative (±) lead to terminal 10.
(b) Check that there is battery voltage with light control
switch is turned on.
If operation is not as specified, replace the relay.If continuity is not as specified, replace the relay.
2. INSPECT DAYTIME RUNNING LIGHT RELAY
(Relay Circuit)
Disconnect the connector from the relay and inspect the
connector on the wire harness side as shown in the chart.

Low Oil Pressure Warning
INSPECTION OF PRESSURE WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the pressure switch
and ground the connector on the wire harness side.
(b) Turn the ignition switch ON, check that t he warning
light lights.
If the warning light does not light, test the bulb.
2. INSPECT PRESSURE SWITCH OPERATION
(a) Disconnect the connector from the switch.
(b) Check that there is continuity between terminal and
ground with the engine stopped.
(c) Check that there is no continuity between terminal
and ground with the engine running.
HINT: Oil pressure should be over 0.3 kg/cm2 (4.3 psi, 29
kPa).
If operation is not as specified, replace the switch.If resistance value is not as specified, replace the send-
er gauge. 3. MEASURE SENDER GAUGE RESISTANCE
Measure the resistance between terminal and ground.

1. READ TYPE A CODE
(a) Turn the ignition switch on.
(b) Turn the set/coast switch on, and keep it on.
(e) Push the main switch on.
(d) Turn the set/coast switch oft.
(e) Meet the conditions listed below.
(f) Read the diagnostic code on the main switch indica-
tor.
HINT:
wTo save time performing the next test, do not turn off the
ignition switch when steps (a) ± (f) are completed.
wChecking of No. 4 code is done with the vehicle jacked
up and the engine idling.
wIf there is no indication code, perform diagnosis ±and
inspection. (See page Be±74)
