CAN COMMUNICATION
System Description
INFOID:0000000001162546
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to
LAN-33, "CAN Communication Signal Chart"
, about CAN communication for detail.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis Description
INFOID:0000000001162547
The ECM controls the display on the instrument panel of certain information relating to the operation of the
engine.
Four functions are involved here: The OBD malfunction indicator [MI (Yellow)] for the EOBD (European On
Board Diagnostics), the pre/post heating, the engine coolant temperature and engine malfunction [MI (Red)].
These four functions are represented by four lights given out by the ECM
GLOW LAMP
This lamp indicates that the glow control system has been activated.
ENGINE COOLANT TEMPERATURE LIGHT
This light is used as an indicator of engine overheating.
• In the event of overheating, it is up to the driver whether to stop the vehicle or not.
MALFUNCTION INDICATOR
The OBD malfunction indicator [MI (Yellow)] is used to alert the driver to the existence of engine control sys-
tem malfunctions involving excessive pollution or if the EOBD system is deactivated.
The ECM makes a request for lighting of the MI (Yellow) only where there is a malfunction present at the end
of three consecutive cycles.
The 3-second visual check upon powering up (automatic test procedure controlled by the IPDM E/R) is per-
formed by the ECM.
In the event of a confirmed OBD malfunction by lighting of the MI, no flashing of the light must be observed fol-
lowing the lighting test.
DTCs Causing MI to Light
ENGINE WARNING LIGHT
In the event of an engine malfunction, the ECM may request the display of an engine warning light [MI (Red)].
HOW TO ERASE DTC, 1ST TRIP DTC AND 2ND TRIP DTC
With CONSULT-III
The emission related diagnostic information in the ECM can be erased by selecting “ALL ERASE” in the
“Description” of “FINAL CHECK” mode with CONSULT-III.
MI OPERATION CHART
Some malfunction must switch on MI to warn driver, that his engine emissions exceed OBD thresholds (Euro 3
x 2.5).
The rule is to switch on MI after 3 consecutive driving cycles (engine start + engine stop + power latch) with a
present OBD malfunction.
To switch off the MI (without CONSULT-III), vehicle has to drive 3 consecutive cycles without present OBD
malfunction.
Ignition switch OFF
→
ON transition, MI remains switched on in pre-drive check mode until engine start.If MI
does not switch off whereas engine is running, there is at least one present OBD malfunction.
