3. Stop vehicle. With engine at idle, touch “SELF-DIAG RESULTS”.
Display shows malfunction experienced since the last erasing
operation.
NOTE:

The details for “TIME” are as follow:
–“0”: Error currently detected with AWD control unit.
–Except for “0”: Error detected in the past and memorized
with AWD control unit.
Detects frequency of driving after DTC occurs (frequency
of turning ignition switch “ON/OFF”).
Display Item List
CAUTION:

If “CAN COMM CIRCUIT [U1000]” is displayed with other DTCs, first perform the trouble diagnosis for CAN communica-
tion.

Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h (19 MPH) or more after
turning ignition switch "OFF" if AWD warning lamp turns ON with system malfunction of “ABS SYSTEM [C1203]”. AWD
warning lamp may not turn OFF if it is normal unless ignition switch turns OFF at once and engine restarts after that.
How to Erase Self-diagnostic Results
1. Perform applicably inspection of malfunctioning item and then repair or replace.
2. Start engine and drive at 30 km/h (19 MPH) or more for approx. 1 minute.
3. Make sure that ABS warning lamp turns OFF.
NOTE:
Make sure that ABS warning lamp turns OFF by driving for a minute at vehicle speed of 30 km/h
(19 MPH) or more after turning ignition switch "OFF" if AWD warning lamp turns ON with system
malfunction of “ABS SYSTEM [C1203]”. AWD warning lamp may not turn OFF if it is normal unless
ignition switch turns OFF at once and engine restarts after that.
4. Turn ignition switch “OFF” to erase memory.
5. Start engine and select “SELF-DIAG RESULTS” mode for “ALL MODE AWD/4WD” with CONSULT-II.
6. Touch “ERASE” on CONSULT-II screen to erase DTC memory.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.
7. Drive at 30 km/h (19 MPH) or more for approx. 1 minute. Be sure AWD warning lamp is OFF.

System ComponentsAES000NO
System DescriptionAES000NP
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
LOW TIRE PRESSURE WARNING CONTROL UNIT
Reads the radio wave signal received by the antenna, and controls
the warning lamp and the buzzer operations as shown below. It also
has a judgement function to detect a system malfunction.
