HINT:
The foglight 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 connecting with relay
block is impossible. If the relay has a malfunction, replace it with
junction block assembly wire harness together.

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.
HINT:
