CONSULT-II Functions (BCM)NKS003RT
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, check power supply and ground of
BCM. If it is normal, refer to GI-40, "
CONSULT-II Data Link Con-
nector (DLC) Circuit" .
4. Touch “FLASHER” on “SELECT TEST ITEM” screen.
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.

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-17, "
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 M1 terminal 29 and
ground.
OK or NG
OK >> Replace BCM. Refer to BCS-17, "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) M1 termi-
nal 29 and multifunction switch harness connector (B) M69 ter-
minal 6.
