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.

page.
If the circuits is not as specified, inspect the circuit connected
to other parts.

HINT:
The horn 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.
