6E-4 ENGINE CONTROL SYSTEM (4JK1/4JJ1)
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
Ty p e 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.

Check - Engine Controls will provide the following
information:
• The identification of the control modules which command the system.
• The ability of the control modules to communicate through the serial data circuit.
• The identification of any stored diagnostic trouble codes (DTCs) and the their statuses.
The use of the Diagnostic System Check - Engine
Controls will identify the correct procedure for
diagnosing the system and where the procedure is
located.
Important: Engine Control System Check Sheet must
be used to verify the complaint vehicle, you need to
know the correct (normal) operating behavior of the
system and verify that the customer complaint is a valid
failure of the system. Reading Flash Diagnostic Trouble Codes (DTC)
The provision for communicating with the ECM is the
Data Link Connector (DLC). The DTC(s) stored in the
ECM memory can be read either through a hand-held
diagnostic scanner such as Tech 2 plugged into the
DLC or by counting the number of flashes of the
malfunction indicator lamp (MIL) or the service vehicle
soon (SVS) lamp when the diagnostic test terminal of
the DLC is grounded. The DLC terminal "1" (diagnostic
request) is pulled "Low" (grounded) by jumped to DLC
terminal "4", which is a ground wire. Once terminals "1"
and "4" have been connected, turn the ignition switch
ON, with the engine OFF. The MIL (except Euro 4
specification) or the SVS lamp (Euro 4 specification)
will indicate a DTC three times is a DTC is present and
history. If more than one DTC has been stored in the
ECM's memory, the DTCs will be output set order with
each DTC being displayed three times. The flash DTC
display will continue as long as the DLC is shorted.
