PROCEDURE

1. INSPECT HEADLIGHT RELAY LH

(a) Check the operation of the headlight relay LH.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the headlight relay LH.

2. INSPECT HEADLIGHT RELAY RH

(a) Check the operation of the headlight relay RH.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the headlight relay RH.

3. INSPECT FOG LIGHT RELAY

(a) Check the operation of the fog light relay.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the fog light relay.

4. INSPECT HEADLIGHT DIMMER RELAY

(a) Check the operation of the headlight dimmer relay.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
3 - 5	Voltage not applied between terminals 1 and 2	10 kΩ or higher
3 - 5	Voltage applied between terminals 1 and 2	Below 1 Ω

If the result is not as specified, replace the headlight dimmer relay.
