DIAGNOSIS SYSTEM (AWD CONTROL MODULE)
CONSULT Function
INFOID:0000000012199367
APPLICATION ITEMS
CONSULT can display each diagnostic item using the diagnostic test modes as follows.
*: The following diagnosis information is erased by erasing.
• DTC
• Freeze frame data (FFD)
ECU IDENTIFICATION
AWD control module part number can be read.
SELF DIAGNOSTIC RESULT
.
When “PRSNT” is displayed on self-diagnosis result.
• The system is presently malfunctioning.
When “PAST” is displayed on self-diagnosis result.
• System malfunction in the past is detected, but the system is presently normal.
FREEZE FRAME DATA (FFD)
The following vehicle status is recorded when DTC is detected and is displayed.
Diagnostic test mode
Function
ECU Identification
AWD control module part number can be read.
Self Diagnostic Result
Self-diagnostic results and freeze frame data can be read and erased quickly.*
Data Monitor
Input/Output data in the AWD control module can be read.
Active Test
Diagnostic Test Mode in which CONSULT drives some actuators apart from the AWD control mod-
ule and also shifts some parameters in a specified range.
Work support
This mode enable a technican to adjust some devices faster and more accurately by following the
indication on the CONSULT.

NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
X: Applicable
HIGH M FLG 2 [0/1]
Measured friction of load is displayed when vehicle throttles down.
• When “0” is displayed: It indicates that friction of load is not high.
• When “1” is displayed: It indicates that friction of load is high.
