INSPECTION

PROCEDURE

1. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY LH (w/ Side Turn Signal Light)

(a) Apply battery voltage and check the operation of the outer mirror LH.

OK:

Condition	Specified Condition
Battery positive (+) → Terminal 6 (MV) Battery negative (-) → Terminal 5 (M+)	Turns upward
Battery negative (-) → Terminal 6 (MV) Battery positive (+) → Terminal 5 (M+)	Turns downward
Battery positive (+) → Terminal 4 (MH) Battery negative (-) → Terminal 5 (M+)	Turns left
Battery negative (-) → Terminal 4 (MH) Battery positive (+) → Terminal 5 (M+)	Turns right
