1.CHECK FUSES AND FUSIBLE LINK
• Check 40A fusible link (letter g , located in the fuse and fusible link box).
• Check 10A fuses [No. 6, 8 and 20, lo cated in the fuse block (J/B)].
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
4, "Schematic" .
2.CHECK BCM POWER SUPPLY CIRCUIT
