Diagnostic Trouble Code (DTC) table

Notes:

The DTC table is organized according to SAE and VAG diagnostic trouble codes.
The "MIL" column labeled specifies the MIL switching condition associated with that DTC.
DTCs that do not switch on the MIL after the malfunction is recognized by the ECM are identified by the MIL switching
condition "Off."
DTCs that do switch on the MIL immediately after the malfunction is recognized by the ECM are identified by the MIL
switching condition "Immed."
DTCs that are recognized by the ECM and switch on the MIL after two consecutive driving cycles (Dcy) are identified by
the MIL switching condition "2 Dcy."
Always correct malfunctions that are designated "immediately" as soon as possible, followed by those malfunctions that
are designated "2Dcy."
When all repairs have been completed, erase DTC memory ( Page 01
-40
) and then generate new readiness code
Page 01
-62

DTCs that are recognized as a result of intermittent malfunctions, or DTCs that are not erased after repairs, are classified
as sporadic malfunctions. These are identified by the designation "SP" appearing in the display.
A sporadic malfunction will be erased if it no longer occurs after 50 driving cycles during which the engine reaches
