Diagnostic Trouble Code (DTC) Type
Definitions

Emission Related DTC

Action Taken When the DTC Sets - Type A

• The ECM illuminates the malfunction indicator

lamp (MIL) when the diagnostic runs and fails.

• The ECM records the operating conditions at the

time the diagnostic fails. The ECM stores this
information in the Freeze Frame/ Failure Records.

Action Taken When the DTC Sets - Type B

• The ECM illuminates the MIL on the second

consecutive driving cycle when the diagnostic runs
and fails.

• The ECM records the operating conditions at the

time the diagnostic fails. The first time the
diagnostic fails, the ECM stores this information in
the Failure Records. If the diagnostic reports a
failure on the second consecutive driving cycle, the
ECM records the operating conditions at the time
of failure and stores this information in the Freeze
Frame and updates the Failure Records.

Conditions for Clearing the MIL/ DTC - Type A or
Type B

• The ECM turns OFF the MIL after 3 consecutive

driving cycles when the diagnostic runs and does
not fail. (Euro 4 Specification)

• The ECM turns OFF the MIL after 1 driving cycle

when the diagnostic runs and does not fail. (Except
Euro 4 Specification)

• A current DTC clears when the diagnostic runs and

passes after 1 driving cycle.

• A history DTC clears after 40 consecutive warm-up

cycles, if no failures are reported.

• Use a scan tool to clear the MIL and the DTC.

Non-Emissions Related DTCs

Action Taken When the DTC Sets - Type C

• The ECM illuminates the Service Vehicle Soon

(SVS) lamp when the diagnostic runs and fails.

• The ECM records the operating conditions at the

time the diagnostic fails. The ECM stores this
information in the Failure Records.

Conditions for Clearing the SVS Lamp/ DTC - Type
C 

• The ECM turns OFF the SVS lamp after 1 driving

cycle when the diagnostic runs and does not fail.

• A current DTC clears when the diagnostic runs and

passes after 1 driving cycle.

• A history DTC clears after 40 consecutive warm-up

cycles, if no failures are reported.

• Use a scan tool to clear the SVS lamp and the

DTC.

Action Taken When the DTC Sets - Type D

• The ECM will not illuminate the MIL or SVS lamp.

• The ECM records the operating conditions at the

time the diagnostic fails. The ECM stores this
information in the Failure Records.

Conditions for Clearing the DTC - Type D

• A current DTC clears when the diagnostic runs and

passes after 1 driving cycle.

• A history DTC clears after 40 consecutive warm-up

cycles, if no failures are reported.

• Use a scan tool to clear the DTC.
