4. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The (Headlight, DIM, Tail relay) is built in engine room junction
block. Also the relay is constructed with a relay block that is in
the junction block as a unit. To disconnect the wire harness con-
necting with relay block is impossible. If the relay has a malfunc-
tion, replace it with junction block assembly wire harness to-
gether.
5. Connector disconnected:
INSPECT AUTOMATIC LIGHT CONTROL SENSOR
CIRCUIT
Disconnect the connector from the sensor and inspect the con-
nector on the wire harness side, as shown in the chart.
HINT:
Ignition switch is ON.
Light control switch is in AUTO.
Vehicle's surroundings are bright.

If circuit is as specified, perform the inspection on the following
page.
If the circuits is not as specified, inspect the circuit connected
to other parts.
6. Connector disconnected:
INSPECT AUTOMATIC LIGHT CONTROL SENSOR
CIRCUIT
Connect the wire harness side connector to the sensor and in-
spect wire harness side connector from the back side, as
shown.

If continuity is not as specified, replace the vanity light assembly
or bulb.
6. INSPECT DOOR COURTESY SWITCH CONTINUITY
(a) Check that continuity exists between terminal and switch
body with the switch ON (switch pin released).
(b) Check that no continuity exists between terminal and
switch body with the switch OFF (switch pin pushed).
If continuity is not as specified, replace the switch.
7. INSPECT DOOR COURTESY LIGHT CONTINUITY
Using an ohmmeter, check that continuity exists between termi-
nals.
If continuity is not as specified, replace the light assembly or
bulb.
