TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: October 20052005 QX56
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8.
Ground is supplied
to BCM terminal 67 and
to combination meter terminal 17
through grounds M57, M61 and M79.
When the remote keyless entry system is triggered by input from the keyfob, the BCM, interpreting it as turn
signal is ON, outputs turn signal from BCM terminals 60 and 61.
The BCM supplies power
through BCM terminals 60 and 61
to front turn/fog lamp LH and RH terminal 2
through front turn/fog lamp LH and RH terminal 3
to grounds E9, E15 and E24, and
to rear turn signal lamp LH terminal 1
through rear turn signal lamp LH terminal 3
to grounds B7 and B19, and
to rear turn signal lamp RH terminal 1
through rear turn signal lamp RH terminal 3
to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamps within combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps when keyfob is
used to activate the remote keyless entry system.

Preliminary CheckEKS00B9V
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES OR FUSIBLE LINK
Check for blown fuses or fusible link.
Refer to LT- 8 3 , "
Wiring Diagram — TURN —" .
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-4, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Disconnect BCM connectors.
2. Check voltage between BCM harness connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open between BCM and fuse or fus-
ible link.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
