Diagnostic Procedure

1. Checking dimmer relay

(a) Check dimmer relay R11.
Standard values:
Use a Specified
Condition multimeter to value
connect pins
Normal 85 - 86 Continuity
04
Apply supply 30 - 87 Continuity
voltage between
pins 85 and 86.

Are check results normal?
Yes > Go to step 2.
No > Replace dimmer relay.

2. Checking combination switch

(a) Check combination switch.
Resistances:

Use a
Condition multimeter to Specified
value
connect pins
Low beam
switch OFF 9 - 3 > 1 MΩ
Low beam 9 - 3 ≤ 2Ω
switch ON

Are check results normal?
Yes > Go to step 3.
No > Replace combination switch.

3. Checking harnesses

(a) Use a multimeter to measure resistances of harnesses between pin 11 of dimmer relay and
pins 1 of left and right low beams.
Resistance: ≤2Ω
Are check results normal?
Yes > Low beam to power short
No > Repair or replace harnesses.
