CONSULT Function

INFOID:0000000010377241

APPLICATION ITEM

CONSULT performs the following functions via CAN communication with CAN gateway.

ECU IDENTIFICATION

The CAN gateway part number is displayed.

SELF DIAGNOSTIC RESULT

Refer to

LAN-115, "DTC Index"

• When “CRNT” 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)

When DTC is detected, a vehicle state shown below is recorded and displayed on CONSULT.

DATA MONITOR

CONFIGURATION

CAUTION:

Follow the instructions listed below. Failure to do this may cause malfunctions to the BCM.:
• When replacing BCM you must perform “Read / Write Configuration” or “Manual Configuration” with

CONSULT.

• Complete the procedure of “Read / Write Configuration” or “Manual Configuration” in order.
• If you set incorrect “Read / Write Configuration” or “Manual Configuration”, incidents might occur.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• Never perform “Read / Write Configuration” or “Manual Configuration” except for new BCM.

Diagnosis mode

Function Description

Ecu Identification

The CAN gateway software number is displayed.

Self Diagnostic Result

Displays the diagnosis results of BCM CAN gateway function.

Data Monitor

Displays real-time input/output data of BCM CAN gateway function.

Configuration

• Read and save the vehicle specification.
• Write the vehicle specification when replacing of BCM.

Item name

Display item

Milage
(Kirometers)
