TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
CONSULT-II SETTING PROCEDURE
Refer to GI-39, "CONSULT-II Start Procedure" .
SELF-DIAG RESULT MODE
Operation Procedure
1. Perform “CONSULT-II Start Procedure”. Refer to GI-39, "CONSULT-II Start Procedure" .
2. Start engine and drive at 30 km/h (19 MPH) or more for approx. 1 minute.
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 line.
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.

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. CHECK OUTPUT SIGNAL WITH UNIFIED METER AND A/C AMP.
With CONSULT-II
1. Turn ignition switch “ON”. (Do not start engine.)
2. Select “DATA MONITOR” mode for “METER A/C AMP” with CONSULT-II.
3. Start the engine, and then make sure that “4WD W/L” display
turns from "ON" to "OFF" after several seconds.
OK or NG
OK >> GO TO 6.
NG >> Perform trouble diagnosis for combination meter. Refer
to DI-18, "
Trouble Diagnosis" .
6. SYMPTOM CHECK
Check again.
OK or NG
OK >>INSPECTION END
NG >> Replace unified meter control unit assembly. Refer to DI-27, "
Disassembly and Assembly of Com-
bination Meter" .
Heavy Tight-Corner Braking Symptom Occurs When The Vehicle Is Driven and
The Steering Wheel Is Turned Fully to Either Side after The Engine Is Started
NDS000DW
NOTE:
Light tight-corner braking symptom may occur depending on driving conditions. This is not malfunc-
tion.
DIAGNOSTIC PROCEDURE
1. 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" .
NO >> GO TO 2.
2. CHECK ACCELERATOR PEDAL POSITION SIGNAL CIRCUIT
Perform self-diagnosis for ECM. Refer to EC-55, "
Emission-Related Diagnostic Information" .
Is any malfunction detected by self-diagnosis?
YES >> Check the malfunctioning system.
NO >> GO TO 3.
