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, Hex-ID, Component-ID, 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.".

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.

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 from MY 2010 with phase in to 50% of MY 2010 and 75% from 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.
