3. CHECK AWD SOLENOID
Check AWD solenoid. Refer to TF-30, "
COMPONENT INSPECTION" .
OK or NG
OK >> GO TO 4.
NG >> Replace electric controlled coupling for malfunction of AWD solenoid. Refer to TF-45, "
Disassem-
bly and Assembly" .
4. 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 >> GO TO 5.
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.
5. SYMPTOM CHECK
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)
NDS000DY
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)
NDS000DZ
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.
Tire pressure
Wear condition
Longitudinal tire size (There is no difference between longitudinal tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)

and transmits a detected air pressure signal in the form of a radio
wave.

LOW TIRE PRESSURE WARNING SYSTEM
Revision: 2006 January2006 M35/M45
RECEIVER
The receiver receives the air pressure signal transmitted by the transmitter in each wheel.
LOW TIRE PRESSURE WARNING CONTROL UNIT
The low tire pressure warning control unit (1) reads the air pressure
signal received by the receiver, and controls the low tire pressure
warning lamp and the buzzer operations. It also has a judgement
function to detect a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the low tire
pressure warning control unit using CAN communication. When a
low tire pressure condition is sensed by the low tire pressure control
unit, the combination meter low tire pressure warning lamp and
buzzer are activated.
Low Tire Pressure Warning Lamp Indication
*: Standard air pressure is for 230 kpa (2.3 kg/cm2 , 33 psi) vehicle. 1. Tire pressure receiver front 2. Tire pressure receiver rear A. Front wheel house
B. Rear wheel house
Refer to GI-11, "
Components" , for the symbols in the figure.
