ON BOARD DIAGNOSTIC 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.
MALFUNCTION INDICATOR LAMP 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) --.
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) with 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 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 MODES
The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability to retrieve and read stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs used within the modes to monitor the engine, and emission related component parameters.
The following table provides a link to all diagnostic modes that monitor all components and systems which influence the emission quality.
Note. Depending on scan tool and protocol used, the information in diagnostic mode 01 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).
DIAGNOSTIC MODE 01 - READ CURRENT SYSTEM DATA

End of procedure
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.
Note. Depending on scan tool and protocol used, the information in diagnostic mode 02 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), or On-Board Diagnostic Monitor Identifier (OBDMID).
Procedure
Connect the scan tool.
Start the engine and run at idle.
Note. If the engine does not start, crank the engine using starter for at least 5 seconds, do not switch the ignition off afterward under any circumstances.
Select "Diagnostic Mode 2: Obtain operating conditions.".

End of procedure
DIAGNOSTIC MODE 03 - READ DTC MEMORY
Diagnostic Mode 03 makes it possible to read emissions-related faults (confirmed DTCs: faults which have activated the MIL) in the ECM and in the TCM.
When the Engine Control Module (ECM) -- recognizes an emission related fault it turns on the Malfunction Indicator Lamp (MIL) -- or if a Electronic Throttle Malfunction is recognized, the Engine Control Module (ECM) -- turns on the Electronic Power Control (EPC) Warning Lamp -- which are both located in the instrument cluster.
Diagnostic Mode 03 is used to retrieve and view any DTC which may be stored in the Engine Control Module (ECM) --.
The DTC's are sorted by SAE code with the DTC tables consisting of a 5-digit alpha-numeric value.
Note. Depending on scan tool and protocol used, diagnostic mode 03 and the information provided may be referred to by a different name.
The following tables provide a breakdown and explanation of the DTC code.

Readiness Code Description
Diagnostics are performed at regular intervals during normal vehicle operation. After repairing an emissions related system, a readiness code is generated by road testing the vehicle.
If a malfunction is recognized during the drive cycle, it will be stored in the DTC memory.
The OBD drive cycle operation will be monitored with a hand held diagnostic tool. Consult the manufacturer's instruction manual for correct tool operation.
The readiness code is erased every time the DTC memory is erased or any time the battery is disconnected. If the DTC memory has been erased or the battery is disconnected, a new readiness code must be generated.
Only erase the DTC memory if a DTC has been stored.
General Recommendations
Most monitors will complete easier and quicker using a "steady-foot" and "smooth" acceleration during the drive cycle operation, cruise, and acceleration modes.
Operating Conditions
For the EVAP monitor test, the coolant temperature and the ambient air temperature must be between 10° C and 35° C with a difference between them no greater than 4° C. The ambient air temperature must not change more than 4° C during the drive cycle procedure (e.g. when driving out of a heated workshop in the winter).
Test requirements
- Erase the DTC memory.
- Coolant temperature must be between 80° C and 110° C.
- The Intake Air Temperature (IAT) must be between 10° C and 35° C.
- Battery voltage must be a minimum of 12.5 volts.
- Fuel tank level 1/4 to 3/4 full.
| WARNING | When performing the drive cycle operation, pay strict attention to driving conditions and please observe and obey all posted speed limits. Failure to follow these instructions may result in personal injury or possible death. |
Drive Cycle Procedure
Connect the scan tool.
