DIAGNOSIS MODE FOR CONSULT-II

“SELF-DIAG [CURRENT]”
A current self-diagnostic results (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.

“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.

“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classification number. This number will
be displayed on the CONSULT-II screen, as shown. When
replacing the diagnosis sensor unit, refer to the part number for
the compatibility. After installation, replacement with a correct
unit can be checked by confirming this classification number on
the CONSULT-II screen.
After repair, make sure the discriminated number of diagnosis
sensor unit installed to vehicle are same. Refer to SRS-45,
"ECU DISCRIMINATED NO." .
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears, then diagnosis mode automatically changes to User mode.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS

“SELF-DIAG [CURRENT]”
A current self-diagnostic result is displayed on the CONSULT-II screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.

“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by touching “BACK” key of CONSULT-II and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.

“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)AHS000HQ

The reading of these results is accomplished “User mode” and “Diagnosis mode”.

After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the User mode. At that
time, the self-diagnostic result is cleared.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
HOW TO ERASE SELF-DIAGNOSIS RESULTS
After a malfunction is repaired, turn ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.

System DescriptionADS000RW
DESCRIPTION

Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.

Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.

On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.

Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:

When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.

If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.

When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)

If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.

When the difference of revolution speed between the front and rear wheel mode the shift occasionally
changes to direct 4-wheel driving conditions automatically. This is not malfunction.
