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

Refer to

DLN-31, "DTC Index"

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

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.
