Diagnostic Procedure

1. Checking combination switch

(a) Check combination switch.

Resistances:

Use a multimeter Specified
Condition
to connect pins value
Low beam switch 9 - 3 > 1 MΩ
OFF 04
Low beam switch 9 - 3
ON ≤ 2 Ω
High beam switch 9 - 12 > 1 MΩ
OFF
High beam switch 9 - 12 ≤ 2 Ω
ON

Are check results normal?
Yes > Go to step 2.
No > Replace combination switch.

2. Checking harnesses
(a) Use a multimeter to measure resistances of harnesses between pin 87 of dimmer relay R11
and pins 1 of left and right combination headlights.
(b) Use a multimeter to measure resistances of harnesses between pin 5 of high beam relay
R30/R31 and pins 2 of left and right combination headlights.
Resistance: ≤2Ω
Are check results normal?
Yes > Both left and right combination headlights to power short
No > Repair or replace harnesses.
