INPUT-OUTPUT VOLTAGE CHART

• The voltage value is based on the body ground.

• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.

• The voltage value is based on the body ground.

• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0 V. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the
lamp.

CONSULT/GST CHECKING SYSTEM

Description

INFOID:0000000009720548

• When CONSULT/GST is connected with a data link connector (A)

equipped on the vehicle side, it will communicate with the control
unit equipped in the vehicle and then enable various kinds of diag-
nostic tests.

• Refer to “CONSULT Software Operation Manual” for more informa-

tion.

Mode

Function

All DTC Reading

Display all DTCs or diagnostic items that all ECUs are recording and judging.

Work Support

This mode enables a technician to adjust some devices faster and more accurately.

Self Diagnostic Results

Retrieve DTC from ECU and display diagnostic items.

Data Monitor

Monitor the input/output signal of the control unit in real time.

CAN Diagnosis

This mode displays a network diagnosis result about CAN by diagram.

CAN Diagnosis Support Monitor

It monitors the status of CAN communication.

Active Test

CONSULT/GST Data Link Connector (DLC) Circuit

INFOID:0000000009720550

INSPECTION PROCEDURE

If the CONSULT/GST cannot diagnose the system properly, check the following items.

NOTE:
The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT access to other systems.
If the GST cannot operate properly, check the circuit based on the information of SAE J1962 and ISO 15031-
3.
