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.)

TIRE PRESSURE MONITORING SYSTEM
Revision: 2007 April2007 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 operations. It also has a judgementfunction 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 warn-
ing control unit, the combination meter low tire pressure warning
lamp is 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
A. Front wheel house
B. Rear wheel house
Refer to GI-11, "
Components" , for the symbols in the figure.

ID Registration ProcedureNES000JY
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. With the activation tool (J-45295) pushed against the front-left
tire pressure transmitter position of the tire air valve, press and
hold the button for 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH, RR LH.
When ID registration of each wheel has been completed, turn
signal lamp blinks.
6. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnosis results
display will not function properly.
ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
4. Adjust the tire pressure to the values shown in the table below for ID registration, and drive the vehicle at
40 km/h (25 MPH) or more for a few minutes.
5. After completing all ID registrations, press “END” to complete the procedure.
6. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .
