(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Check the resistance between the lamp
connector and body earth.
•
Resistance between A-31 <headlamp (LO) RH>
headlamp assembly connector terminal No.8
and body earth
• Resistance between A-39 <headlamp (LO)
LH> headlamp assembly connector terminal
No.8 and body earth
•
Resistance between A-21 <headlamp (HI) RH>
headlamp assembly connector terminal No.2
and body earth
• Resistance between A-15 <headlamp (HI)
LH> headlamp assembly connector terminal
No.2 and body earth
•
Resistance between C-01 <high-beam indicator>
combination meter connector terminal No.5
and body earth
OK: 2
Ω or less
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.
