1. CHECK FUSE

Check 15A fuse [No.17, located in fuse block (J/B)]

Check 15A fuse [No.18, located in fuse block (J/B)] (With Intelligent Key)

Check 50A fusible link (letter M located in the fuse and fusible link box)
NOTE:
Refer to BL-21, "
Component Parts and Harness Connector Location" .
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-
3, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM connector M4 terminals 42, 55 and
ground.
