Trouble Diagnosis Chart for Symptoms

ADS000VG

If AWD warning lamp turns ON, perform self-diagnosis. Refer to 

TF-24, "SELF-DIAG RESULT MODE"

 .

NOTE:

●

Light tight-corner braking symptom may occur depending on driving conditions in AUTO mode. This is not malfunction.

●

Heavy tight-corner braking symptom occurs when vehicle is driven in the following conditions: LOCK mode, steering
wheel is turned fully to either sides, and accelerator pedal was depressed.

Perform each diagnostic test mode according to each service
procedure.

SELF-DIAG RESULT MODE
Operation Procedure

1.

Perform “CONSULT-II SETTING PROCEDURE”. Refer to 

TF-23, "CONSULT-II SETTING 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.
