ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT HEADLIGHT DIMMER RELAY

(a) Check the resistance.

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

Standard Resistance:

Tester Connection

Condition

Specified Condition

3 - 5

When battery voltage not applied

10 kΩ or higher

3 - 5

When battery voltage to terminals 1 and 2

Below 1 Ω

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

2. INSPECT LIGHT CUT RELAY

(a) Check the resistance.

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

Standard Resistance:

Tester Connection

Condition

Specified Condition

3 - 5

When battery voltage not applied

10 kΩ or higher

3 - 5

When battery voltage to terminals 1 and 2

Below 1 Ω

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

3. INSPECT HEADLIGHT RELAY (w/ Headlight Relay)

(a) Check the resistance.

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

Standard Resistance:

Tester Connection

Condition

Specified Condition

3 - 5

When battery voltage not applied

10 kΩ or higher

3 - 5

When battery voltage to terminals 1 and 2

Below 1 Ω

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

4. INSPECT NO. 1 DAY TIME RUNNING LIGHT RELAY (for LED Type)

(a) Check the resistance.

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

Standard Resistance:
