6E–105

ECM DIAGNOSTIC TROUBLE CODES (DTC)

Type A

• Emission related.

• Requests illumination of the MIL (Malfunction Indicator Lamp = Check Engine Lamp) of the first trip with a fail.

• Stores a history DTC on the first trip.

• Stores a freeze frame (If empty).

• Stores a fail record.

• Updates the fail record each time the diagnostic test fails.

Type B

• Emission related.

• “Armed” after one trip with fail.

• “Disarmed” after one trip with a pass.

• Requests illumination of the MIL on the second consecutive trip with a fail.

• Store a history DTC on the second consecutive trip with a fail. (The DTC will be armed after the first fail.)

• Stores a freeze frame on the second consecutive trip with a fail (If empty).

• Stores a fail record when the first test fails (not dependent on consecutive trip).

• Updates the fail record each time the diagnostic test fails.

Type D

• Non emission related.

• Does not request illumination of any lamp.

• Stores a history DTC on the first trip.

• Does not store a freeze frame.

• Stores fail record when test fails.

• Updates the fail record each time the diagnostic test fails.
