3. CHECK SYSTEM FOR AWD SOLENOID
Perform trouble diagnoses for AWD solenoid system. Refer to TF-27, "
AWD Solenoid" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK ELECTRIC CONTROLLED COUPLING
1. Turn ignition switch “OFF”.
2. Set the selector lever to “N” (neutral) position and disengage the parking brake.
3. Lift up the vehicle.
4. Rotate the rear propeller shaft by hand.
5. Hold front propeller shaft lightly.
Does front propeller shaft rotate?
YES >> Replace electric controlled coupling for mechanical malfunction (clutch sticking etc.). Refer to TF-
45, "Disassembly and Assembly" .
NO >> GO TO 5.
5. CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> GO TO 6.
6. CHECK AWD CONTROL UNIT
Check AWD control unit input/output signal. Refer to TF-19, "
AWD Control Unit Input/Output Signal Reference
Va l u e s" .
OK or NG
OK >>INSPECTION END
NG >> Check AWD control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
Vehicle Does Not Enter AWD Mode Even Though AWD Warning Lamp Turned To
OFF

Revision: 2004 November 2004 FX35/FX45
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
–When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
2. Sleep status
–When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 10 ms, and only input from light switch
system is accepted.
CAN Communication System DescriptionAKS0056Q
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS0080E
Refer to LAN-6, "CAN Communication Unit" .
