TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2004 November 2004 FX35/FX45
3. CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> Replace electric controlled coupling for mechanical malfunction (mechanical engagement of
clutch is not possible.). Refer to TF-45, "
Disassembly and Assembly" .
While Driving, AWD Warning Lamp Flashes Rapidly (When Flashing In Approx.
1 Minute And Then Turning OFF)
ADS000U1
NOTE:
Rapid flashing: 2 times/second
This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before lamp flashes rapidly. Both cases are not malfunction.
When this symptom occurs, stop vehicle and allow it to idle for some times. Flashing will stop and system will
be restored.
While Driving, AWD Warning Lamp Flashes Slowly (When Continuing To Flash
Until Turning Ignition Switch OFF)
ADS000U2
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
