While driving, AWD warning lamp flashes
rapidly. (When flashing in approx. 1 minute
and then turning OFF.)
Rapid flashing: 2 times/second While driving Protection function is activated due to
heavy load to electric controlled cou-
pling. (AWD system is not malfunction-
ing. Also, optional distribution of torque
sometimes becomes rigid before lamp
flashes rapidly, but it is not malfunction.) TF-37
While driving, AWD warning lamp flashes
slowly. (When continuing to flash until turn-
ing ignition switch OFF)
Slow flashing: 1 time/2 secondsWhile driving

CONSULT-II Function (ALL MODE AWD/4WD)NDS000A5
FUNCTION
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING PROCEDURE
Refer to GI-38, "CONSULT-II Start Procedure" .
SELF-DIAG RESULT MODE
Operation Procedure
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "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. Diagnostic test mode Function
