TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2007 April2007 M35/M45
3. CHECK SYSTEM FOR AWD SOLENOID
Perform trouble diagnosis for AWD solenoid system. Refer to TF-28, "
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. SYMPTOM CHECK
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-20, "
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
NDS000DX
DIAGNOSTIC PROCEDURE
1. CHECK AWD WARNING LAMP
Turn ignition switch “ON”. (Do not start engine.)
Does AWD warning lamp turn on?
YES >> GO TO 2.
NO >> Go to TF-33, "
AWD Warning Lamp Does Not Turn ON When The Ignition Switch Is Turned to ON"
.
2. CHECK SYSTEM FOR CAN COMMUNICATION LINE
Perform self-diagnosis. Refer to TF-22, "
SELF-DIAG RESULT MODE" .
Is the
“CAN COMM CIRCUIT [U1000]” displayed?
YES >> Perform trouble diagnosis for CAN communication line. Refer to TF-32, "CAN Communication
Line" .
