Replace the faulty bulb.
13. Disconnect under-dash fuse/relay box connectors F (34P) and G (21P).
14. Disconnect the both headlight (high beam) 2P connectors.
15. Check for continuity between right headlight (high beam) 2P connector terminal No. 2 and under-dash
fuse/relay box connector F (34P) terminal No. 22.
Go to step 16.
Repair an open in the wire between the right
headlight (high beam) and the under-dash fuse/
relay box. 16. Check for continuity between left headlight (high
beam) 2P connector terminal No. 2 and under-dash
fuse/relay box connector G (21P) terminal No. 15.
Go to step 17.
Repair an open in the wire between the left
headlight (high beam) and the under-dash fuse/
relay box.
17. Check for continuity between headlight (high beam) 2P connector terminal No. 1 and body
ground.
Faulty MICU; replace the under-dash fuse/
relay box (see page 22-66).
Repair an open in the BLK wire or poor
ground (G 201-right side, G301-left side).
