6E-44 ENGINE CONTROL SYSTEM (4JK1/4JJ1)
Diagnostic Starting Point - Engine Controls
Begin the system diagnosis with Diagnostic System
Check - Engine Controls. The Diagnostic System
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.

Scan Tool Data List
The Engine Scan Tool Data List contains all engine
related parameters that are available on the scan tool.
A given parameter may appear in any one of the data
lists, and in some cases may appear more than once,
or in more than one data list in order to group certain
related parameters together. Use the Engine Scan Tool
Data List only after the following is determined:
• The Engine Controls - Diagnostic System Check is completed. • On-board diagnostics are functioning properly.
Scan tool values from a properly running engine may
be used for comparison with the engine you are
diagnosing. The Engine Scan Tool Data List represents
values that would be seen on a normal running engine.
Only the parameters listed below are referenced in this
service manual for use in diagnosis.

Scan Tool Data Definitions
This information will assist in emission or driveability
problems. The displays can be viewed while the vehicle
is being driven. Always perform the Diagnostic System
Check - Engine Controls first. The Diagnostic System
Check will confirm proper system operation.
Engine Speed
This parameter displays the rotational speed of the
crankshaft as calculated by the ECM based on inputs
from the crankshaft position (CKP) sensor or camshaft
position (CMP) sensor.
Desired Idle Speed
This parameter displays the idle speed requested by
the ECM. The ECM will change desired idle speed
based on engine coolant temperature and other inputs.
Calculate Engine Load
This parameter displays the engine load in percent
based on inputs to the ECM from various engine
sensors. The scan tool will display a lower percentage
when the engine is at idle with little or no load. The
scan tool will display a higher percentage when the
engine is running at high engine speed under a heavy
load.
Coolant Temperature
This parameter displays the temperature of the engine
coolant as calculated by the ECM using the signal from
the engine coolant temperature (ECT) sensor. The
scan tool will display a low temperature when the ECT
sensor signal voltage is high, and a high temperature
when the ECT sensor signal voltage is low.
Engine Coolant Temperature Sensor
This parameter displays the voltage signal sent to the
ECM from the engine coolant temperature (ECT)
sensor. ECT sensor is a range of value indicating a low
voltage when the temperature is high, and a high
voltage when the temperature is low.
Intake Air Temperature
This parameter displays the temperature of the intake
air as calculated by the ECM using the signal from the
intake air temperature (IAT) sensor. The scan tool will
display a low temperature when the IAT sensor signal
voltage is high, and a high temperature when the IAT
sensor signal voltage is low. Intake Air Temperature Sensor
This parameter displays the voltage signal sent to the
ECM from the intake air temperature (IAT) sensor. IAT
sensor is a range of value indicating a low voltage
when the temperature is high, and a high voltage when
the temperature is low.
Fuel Temperature
This parameter displays the temperature of the fuel as
calculated by the ECM using the signal from the fuel
temperature (FT) sensor. The scan tool will display a
low temperature when the FT sensor signal voltage is
high, and a high temperature when the FT sensor
signal voltage is low.
Fuel Temperature Sensor
This parameter displays the voltage signal sent to the
ECM from the fuel temperature (FT) sensor. FT sensor
is a range of value indicating a low voltage when the
temperature is high, and a high voltage when the
temperature is low.
MAF (Mass Air Flow)
This parameter displays the air flow into the engine as
calculated by the ECM based on the mass air flow
(MAF) sensor input. The scan tool will display a high
value at higher engine speeds, and a low value at lower
engine speed.
MAF Sensor (Mass Air Flow)
This parameter displays the voltage signal sent to the
ECM from the mass air flow (MAF) sensor. MAF sensor
is a range of value indicating a low voltage at lower
engine speed, and a high voltage at a higher engine
speeds.
Barometric Pressure
This parameter displays the barometric pressure
(BARO) as calculated by the ECM using the signal from
the BARO sensor. The scan tool will display a low
barometric pressure in high altitude area.
Barometric Pressure Sensor
This parameter displays the voltage signal sent to the
ECM from the barometric pressure (BARO) sensor.
BARO sensor is a range of value indicating a low
voltage in high altitude area, and a middle voltage in
sea level.
