• The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the

system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.

• The step by step voltage drop test can identify a component or wire with too much resistance.

CONTROL UNIT CIRCUIT TEST 

System Description
• When the switch is ON, the control unit lights up the lamp.

CASE 1

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.

CONSULT/GST CHECKING SYSTEM

Description

INFOID:0000000010242497

• 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

Send the drive signal from CONSULT to the actuator. The operation check can be performed.

ECU Identification

Display the ECU identification number (part number etc.) of the selected system.

Function Test

This mode can show results of self-diagnosis of ECU with either “OK” or “NG”. For engines, more 
practical tests regarding sensors/switches and/or actuator are available.

Configuration

Function to READ/WRITE vehicle configuration.

SRT&P-DTC Confirmation

The state of System Readiness Test (SRT) items, the presence or absence of permanent DTC*, 
and driving conditions can be checked.

DTC work support

DTC reproduction procedure can be performed speedily and precisely.

Others

Other results or histories, etc. that are recorded in ECU are displayed.

CONSULT/GST CHECKING SYSTEM

*1: If GST application is equipped, functions in accordance with SAE J1979 and ISO 15031-5 can be used.

*2: Permanent DTC is not applied for regions where it is not mandated.

*3: Used only in models with gasoline engine.

*4: Used only in models with diesel engine.

CONSULT/GST Data Link Connector (DLC) Circuit

INFOID:0000000010242499

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.
