1 General Information
With the introduction of the new Anti-Lock Braking and Traction Control (ABS-TC) system, fitted to MY 2004 AWD
Wagon models and the fact that this system communicates via the Class 2 serial data bus, the Powertrain Interface
Module (PIM) has undergone a number of changes. This has also meant that the Diagnostic Trouble Codes (DTCs) have
also been revised and updated, with a changed numbering structure.
Now the PIM acts as a communication translator between the Powertrain Control Module (PCM) and the ABS-TC control
module on the Class 2 serial data bus and other control modules on the UART serial data circuit. In addition to control of
the starter relay operation, the PIM also now controls the operation of warnings triggered by the ABS-TC control module.
These changes have meant that the PCM Normal Mode and Data Display have been updated. For further general
information regarding these changes, refer to Section 6C 3-1 General I nfor mat ion, in the MY 2004 AWD Wagon Service
Information.
In conjunction with these changes, the TECH 2 scan tool software has also undergone an updating process.
All of these changes and the effect they have on TECH 2 displays, are covered in this Section. For all remaining TECH 2
diagnostic information, refer to Section 6C3-2 Diagnosis, in the MY 2003 VY and V2 Series Service Information.
Powertrain Management – Diagnosis – GEN III V8 Engine Page 6C3-2-3

2 TECH 2 Display Modes
Access to the TECH 2 display modes for the Powertrain Interface Module (PIM), is via F3: Body from the Main Menu,
then F1: Powertrain Interface Module.
Selections then, are:
F0: Normal Mode
F1: Diagnostic Trouble Codes
F2: Data Display
F3: Snapshot
F4: Miscellaneous Tests
F5: Security
F0: Normal Mode
F0: PCM Normal Mode
In this test mode, TECH 2 will display various engine and transmission data parameters that are being continually
transmitted to other control modules via the serial data circuit normal mode message. The information in the following
tables may b e used for comparison, if a status report is being sent from t he PIM.
1. After completing the Powertrain OBD System Check
2. Finding the on-board diagnostics are functioning properly and;
3. No diagnostic DTCs are displayed.
Test Description
NOTE
The number(s) below refer to the step number(s)
on the diagnostic table.
1 TECH 2 – F0: PCM/PIM Normal Mode will display scan positions that will be displayed in order. TECH 2 will
display nine (9) scan position parameters at a time. The down arrow button will scroll down through all of the scan
positions one at a time. After TIME FROM START parameter is displayed, pressing the down arrow button again
will display scan position parameters starting at the top of the list again.
2 Units Displayed are the available ways of displaying what each parameter is currently operating in, or a value that
is being sensed or being issued by the PCM.
3 Typical Data Value is separated into two parts. These displayed values are typical of a normally operating vehicle.
The Ignition On comparison should be performed first as this may lead to a quick identification of a failure. The
Engine Running data should be compared to the IGNITION ON data as a diagnostic check to make sure the
component or system is operating properly.
4 Ignition On values are the typical values that should be seen on TECH 2 with the ignition ON and engine stopped.
Temperature sensors should be compared to the actual temperatures by allowing the sensor to cool overnight and
then comparing their values. A difference of 3-5° C from the actual temperature may indicate a problem with the
sensor. Use the diagnostic aids table for that sensor to compare the resistance to temperature values.
5 Engine Running typical data values are an average of display values recorded from normally operating vehicles at
normally operating temperature. They are intended to represent what a normally functioning system would typically
display.

F0: PCM Normal Mode Descriptions
A list of explanations for each data message displayed on TECH 2 is listed below. This information will assist in
diagnosing emission or driveability problems. The displays can be viewed while the vehicle is being driven. Refer to the
Powertrain OBD System Check for additional information.
Engine Speed: TECH 2 Displays a range of 0 to 9999 RPM
The engine speed is computed by the PCM from the fuel control reference input. It should remain close to desired idle
speed under various engine loads with engine idling.
Powertrain Management – Diagnosis – GEN III V8 Engine Page 6C3-2-5
Page 6C3-2-5
Coolant Temperature: TECH 2 Displays a range of -39°C to 140°C
The Engine Coolant Temperature (ECT) Sensor is mounted in the cylinder head of the left bank. The PCM applies 5.0
volts to the ECT sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes.
When the sensor is cold (internal resistance high), the PCM monitors a high signal voltage and interprets the voltage as
a cold engine. As the sensor warms (internal resistance decreases), the voltage signal decreases and the PCM
interprets the lower voltage as a warm engine.
Barometric Pressure: TECH 2 Displays a range of 0 to 200 kPa
The BARO reading is displayed in kPa and represents the altitude of the vehicle for the transmission control. At sea level
the BARO reading is about 101 kPa. At 3,048 meters the BARO reading is about 96 kPa.
Vehicle Speed: TECH 2 Displays a range of 0 to 255 km/h
The vehicle speed sensor signal is converted into km/h for display.
A/C Clutch: TECH 2 Displays "ON" or "OFF"
Represents the commanded state of the A/C clutch control relay. Clutch should be engaged when ON is displayed.
A/C Pressure: TECH 2 Displays a range of 0 to 3195 kPa
The kPa displayed indicates that the PCM is monitoring an A/C Refrigerant Pressure signal voltage which is too high or
too low to allow the A/C compressor clutch to engage.

F1: Diagnostic Trouble Codes
In this test mode, PIM DTCs can be displayed or cleared. When F1: Diagnostic Trouble Codes is selected there are an
additional two modes:
F0: Read DTC Information
A listing of all (if any) DTC’s that have been set by the PIM will be displayed. TECH 2 will also display Diagnostic Trouble
Code History Da ta.
Diagnostic Trouble Code History Data
When the PIM detects an operating parameter which is outside its calibrated values, it will set a Diagnostic Trouble Code
(DTC) and store this DTC into its memory as a current DTC. When a current DTC is set the Check Powertrain MIL may
be activated.
When a DTC is set, the PIM also stores the following history data for each DTC:
DTC Number ............................The DTC number is the number used to identify a particular fault condition.
DTC Status ..............................Current or History
Occurrence Count (0 to 255)....The occurrence count is the number of times the particular fault condition has been
detected.
History Count (0 to 255)............The history count is the number of ignition cycles that have occurred since the fault was
last detected. A count of 0 indicates the fault has occurred on the current ignition cycle,
while a count of 255 indicates that the fault occurred 255 or more ignition cycles ago.
The occurrence and history counters provide a means of determining how often the fault has oc curred, and how long it
has been since the fault last occurred. For instance, if the DTC occurrence count is 1, and the history count is 201, then it
can be determined that the fault condition existed only once, and it happened 201 ignition cycles ago (and has not been
detected since). Another example would be an occurrence count of 4 and a history count of 0. This would indicate that
the fault has been detected a total of four times, and that it was detected on the current ignition cycle.
Current and History DTCs and DTC history data can be read and cleared using TECH 2.
TECH 2 will display the DTC information in the following manner:
F0: Read DTC Information
When this mode is selected, TECH 2 will display the
following DTC information:
The DTC Number
DTC Status either Current or History
DTC Description

F5: Security
In this test mode, TECH 2 provides the user with the capability of linking the BCM to the PCM/PIM.
A precondition to all security features is: The vehicle security number must be entered an d the theft deterrent system
must be disarmed and the ignition must be switched on with a programmed remote coded key. When linking the BCM to
the PCM/PIM, or programming a remote key, TIS approval is also required.
F0: BCM Link to PCM/PIM (All): In this test mode, TECH 2 provides the user with the capability of linking the BCM to
the PCM/PIM. If the BCM, PCM or PIM is replac ed, the BCM must be linked to the PCM/PIM. Otherwise, the vehicle will
