ON BOARD DIAGNOSTIC SYSTEMS

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 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.

DIAGNOSTIC MODES 01 - 09

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, erase 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.

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

Diagnostic Mode 01 makes it possible to access current emissions-related measured values and diagnostic data. The original measured values (no replacement values), input and output data and system status information are displayed using Diagnostic Mode 1.

Test requirement

Coolant temperature at least 80 °C.

Procedure

Connect the scan tool.

Start the engine and run at idle.

Select "Diagnostic Mode 1: Obtain data."

From the following table, select the desired the "PID" that is to be monitored, e.g. "PID $05 Coolant temperature".

Switch the ignition OFF.

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.

Select "Diagnostic Mode 2: Obtain operating conditions."

From the following table, select the desired the "PID", e.g. "PID $05 Coolant temperature" that is to be monitored.

The current values of the component or system that is being monitored will be displayed on the scan tool screen.

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 ECM recognizes an emission related fault it turns on the malfunction indicator lamp. If an electronic throttle malfunction is recognized, the ECM turns on the electronic power control warning lamp. Both are located in the instrument cluster.

The DTCs 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.

Then select Mode 4: Reset/delete diagnostic data.

The scan tool will display: Diagnostic data are being erased.

Switch the ignition OFF.

DIAGNOSTIC MODE 06 - READ TEST RESULTS FOR SPECIFIC DIAGNOSTIC FUNCTIONS

Diagnostic Mode 06 makes it possible to retrieve test results for special components and systems which are continuously or not continuously monitored. If the diagnosis of a system is complete, the diagnostic result and the corresponding thresholds are saved and displayed in mode 06. This data remains saved (even with the ignition off) until either new diagnostic results become available or the DTC memory is erased.

The min & max values for each individual test in Mode 06 represent the minimum & maximum operating values for a properly operating system. This data is provided to the individual aftermarket scan tool companies for development of their scan tool. Depending on the scan tool being used, the min & max values shown may vary, or be rounded up or down to the nearest decimal point depending on the aftermarket scan tool company's development process. e.g.

	Minimum Value
GST information documentation	0.3499
Aftermarket scan tool display	0.35

Note. Depending on the scan tool and protocol used, the information displayed in diagnostic mode 06 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 0A - PERMANENT FAULT CODES

This vehicle is equipped with Mode 0A.

Diagnostic Mode 0A - Check Permanent DTC Memory (Request emissions-related diagnostic trouble codes with permanent status after code clear) Permanent Fault Codes starting in MY 2010 with phase in of 50%, and 75% phase in for MY 2011, with 100% compliance for MY 2012. Mode 0A is supported by OBD control modules in US vehicle market specifically. Mode 0A enables the request of all OBD-relevant faults with the status "Permanent Fault Code". Permanent Fault Codes are Confirmed Fault Codes that are currently activating the MIL. That means faults that are still displayed in Mode 03 but no longer activate the MIL (History Fault Codes) are not Permanent Fault Codes. Permanent Fault Codes are updated in Mode 0A immediately after switching the ignition off. A newly detected Permanent Fault Code is only visible after switching the ignition off/on in Mode 0A. Permanent Fault Codes may only be erased in the control module after they are corrected as long as the last diagnostic result was a PASS and the MIL is no longer activated by this fault. The Permanent Fault Codes should be erased from Mode 0A at the same time the MIL switches off when the ignition is switched off/on. Permanent Fault Codes may not be erased by clearing the DTC memory or disconnecting the power supply. Permanent Fault Codes may only be erased after clearing the DTC memory under the following conditions: as long as no FAIL diagnostic result was detected for a Permanent Fault Code and at least one PASS diagnostic result was detected, and the Minimum Trip Conditions were met in any drive cycle after erasing the DTC memory. The engine control module relays the message "Minimum Trip conditions met" to all other OBD control modules via CAN. Permanent Fault Codes may NOT be erased if the diagnostic result is FAIL after clearing the DTC memory. A Pending Fault Code should be stored and the DTC memory will be overwritten with new Freeze Frame data (Exception: If the Pending Fault Code is corrected without a Confirmed Fault Code being detected, the Permanent Fault Code may also be erased under the conditions described below.) - Permanent Fault Codes should be erased in engine control modules after Update Programming. The procedure in Mode 01 through Mode 09 in the scan tool is not affected by implementation of the Permanent Fault Codes.

Diagnostic Mode $0A				Mode Status
Permanent Fault Codes				Supported
