ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Diagnosis Description

INFOID:0000000010379035

This system is an on board diagnostic system that records exhaust emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator
(MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diagnostic
tool (GST: Generic Scan Tool).
NOTE:
OBD is not applied for regions where it is not mandated.

MALFUNCTION INDICATOR LAMP

When detecting a DTC that affects exhaust gas, the exhaust emis-
sion-related control module transmits a malfunction indicator signal
to ECM via CAN communication line.
ECM prioritizes the signal received from the exhaust emission-
related control module and the ECM-stored DTC that affects exhaust
gas and transmits a malfunction indicator lamp signal to the combi-
nation meter via CAN communication line.
The combination meter turns ON the MIL, according to the signal
transmitted from ECM, and alerts the driver of malfunction detection.

CONSULT Function

INFOID:0000000010379036

FUNCTION

*: The following emission-related diagnostic information is cleared when the ECM memory is erased.

• Diagnostic trouble codes

SELF DIAGNOSTIC RESULT MODE

Self Diagnostic Item

Regarding items detected in “SELF-DIAG RESULTS” mode, refer to 

ECH-71, "DTC Index"

.

How to Erase DTC

With CONSULT

NOTE:
If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 12 min-
utes and then turn it ON (engine stopped) again.
1.

Select “ENGINE” with CONSULT.

2.

Select “SELF-DIAG RESULTS”.

3.

Touch “ERASE”. (DTC in ECM will be erased)

Function

Self Diagnostic Result

Self-diagnostic results such as DTC can be read and erased quickly.*

Data Monitor

Input/Output data in the ECM can be read.

Work support

This mode enables a technician to adjust some devices faster and more accurately by following 
the indications on the CONSULT unit.

Active Test

Diagnostic Test Mode in which CONSULT drives some actuators apart from the ECMs and also 
shifts some parameters in a specified range.

ECU Identification

ECM part number and homologation number can be read.
