ON BOARD DIAGNOSTIC (OBD) SYSTEMS

OBD II

"OBD" is an abbreviation for the On Board Diagnostic System.

California OBD-II applies to all gasoline engine vehicles up to 14, 000 lbs. Gross Vehicle Weight Rating (GVWR) starting in the 1996 MY and all diesel engine vehicles up to 14, 000 lbs. GVWR starting in the 1997 MY.

Several states in the Northeastern United States have chosen to adopt the California emission regulations starting in the 1998 MY and are known as "Green States".

Green States receive California-certified vehicles for passenger cars and light trucks up to 6, 000 lbs. GVWR. Starting in the 2004 MY, Federal vehicle over 8, 500 lbs. will start phasing in OBD-II.

Starting in 2004 MY, gasoline-fueled Medium Duty Passenger Vehicles (MDPVs) are required to have OBD-II. Federal OBD-II applies to all gasoline engine vehicles up to 8, 500 lbs. GVWR starting in the 1996 MY and all diesel engine vehicles up to 8, 500 lbs. GVWR starting in the 1997 MY.

OBD-II system implementation and operation is described in the remainder of this document.

SERIAL DATA LINK (MIL) ILLUMINATION

"MIL" is an abbreviation for the Malfunction Indicator Lamp (MIL) --.

If the Engine Control Module (ECM) -- recognizes a malfunction that leads to increased emissions values, it indicates them by lighting the Malfunction Indicator Lamp (MIL) -- which is located in the instrument cluster.

The Engine Control Module (ECM) -- switches on the Malfunction Indicator Lamp (MIL) -- after the ignition is switched on. Shortly after the engine is started, The Malfunction Indicator Lamp (MIL) -- goes out if the Engine Control Module (ECM) -- does not detect a malfunction that increases the emissions values.

If the Engine Control Module (ECM) -- recognizes a malfunction that leads to increased emissions during the operation of the engine, the Engine Control Module (ECM) -- switches on the Malfunction Indicator Lamp (MIL) -- and an entry is stored in the DTC memory of the Engine Control Module (ECM) --.

CONTROLLER AREA NETWORK (CAN) DATA LINK

"CAN" is an abbreviation for Controller Area Network.

The Engine Control Module (ECM) -- communicates with all databus capable control modules by a CAN Data Link.

The databus capable control modules (i.e. Engine Coolant temperature Sensor) are connected by two data bus wires which are twisted together (CAN_High and CAN_Low), and exchange information (messages) to the Engine Control Module (ECM) --. Missing information on the databus is then recognized and stored as a malfunction.

The Engine Control Module (ECM) -- illuminates the Malfunction Indicator Lamp (MIL) -- through the CAN data link and tells the Malfunction Indicator Lamp (MIL) -- to turn on, turn off, or blink.

Electronic Power Control (EPC) Warning Lamp

"EPC" is an abbreviation that stands for the Electronic Power Control (E-gas).

The Engine Control Module (ECM) -- monitors all EPC components after the ignition is switched on.

If a malfunction is recognized in the EPC system during the operation of the engine, the Engine Control Module (ECM) -- switches on the Electronic Power Control (EPC) Warning Lamp -- which is located in the instrument cluster and an entry is stored in the DTC memory of the Engine Control Module (ECM) --.

DIAGNOSTIC MODE 02 - READ OPERATING CONDITIONS

When an emissions-related fault (pending DTC, visible in mode 07) is first detected, operating conditions are stored. Mode 02 makes it possible to access this freeze frame data as soon as this fault is shown in mode 03. Each control module only shows freeze frame data for one fault via mode 02. Therefore, there are two priority levels. If there is a malfunction with higher priority, the freeze frame data is overwritten.

Fault with higher priority: Misfire malfunction or fuel trim malfunction.

Fault with normal priority: All other emissions-related faults.

Depending on scan tool and protocol used, the information displayed in diagnostic mode 02 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.
