Display Item List
BCM diagnosis part Diagnosis mode Description
FLASHERDATA MONITOR Displays BCM input data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending driving signal to them.
ALL SIGNALS Monitors all the signals.
SELECTION FROM MENU Selects items and monitor them.
Monitor item Contents
IGN ON SW “ON/OFF” Displays “IGN position (ON)/OFF, ACC position (OFF)” judged from the ignition switch signal.
HAZARD SW “ON/OFF” Displays “hazard ON (ON)/hazard OFF (OFF)” status, determined from hazard switch signal.
TURN SIGNAL R “ON/OFF” Displays “turn right (ON)/other (OFF)” status, determined from lighting switch signal.
TURN SIGNAL L “ON/OFF” Displays “turn left (ON)/other (OFF)” status, determined from lighting switch signal.

4. CHECK TURN SIGNAL LAMP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector, front combination lamp RH and LH connector, side turn signal lamp RH and
LH connector, rear combination lamp RH and LH connector.
3. Check continuity between BCM harness connector (A) and front
combination lamp (RH and LH) harness connector (B).
4. Check continuity between BCM harness connector (A) and side
turn signal lamp (RH and LH) harness connector (B).
5. Check continuity between BCM harness connector (A) and rear
combination lamp (RH and LH) harness connector (B).
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5. CHECK SIGNAL LAMP CIRCUIT (SHORT CIRCUIT)
Check continuity between BCM harness connector and ground.
OK or NG
OK >> Replace BCM. Replace BCM if turn signal lamp does
not work after setting the connector again. Refer to
BCS-15, "
Removal and Installation of BCM" .
NG >> Repair harness or connector.

Hazard Warning Lamp Does Not Operate But Turn Signal Lamp OperateNKS003RV
1. CHECK CIRCUIT BETWEEN HAZARD SWITCH AND BCM
With CONSULT-II
1. Select “BCM” on CONSULT-II. Select “FLASHER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure “HAZARD SW” turns ON-OFF linked with operation
of multifunction switch (hazard switch).
Without CONSULT-II
Check voltage between BCM harness connector and ground.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
NG >> GO TO 2.
2. CHECK HAZARD SWITCH BCM CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and multifunction switch connector.
3. Check continuity between BCM harness connector (A) and mul-
tifunction switch harness connector (B).
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.When hazard switch is ON position : HAZARD SW ON
