• Thorough inspection of the wiring circuits and connectors listed in the diagnostic procedures must be performed,
otherwise misdiagnosis may occur.
• Inspect the electrical circuitry or connector terminals that are suspected to be causing the complaint for the
following conditions:
• backed-out connector terminals,
• improper wiring connector mating,
• broken wiring connector locks,
• damaged connector terminals, and
• physical damage to the wiring harness.
• Before replacing a component, inspect its connector terminal for corrosion or deformation that may cause the fault
condition.
Preliminary Checks
The PIM preliminary check examines easily accessible components which may cause problems with the PIM. This visual
and physical inspection procedure may quickly identify the fault condition and eliminate the need for additional diagnosis.
• Refer to Service Techlines for relevant information regarding the fault condition.
• Ensure the battery is fully charged.
• Check the battery connections for corrosion or a loose terminal.
• Perform a visual and physical inspection of the following:
• PIM component wiring harness and terminals for proper connections, pinches or cuts, and
• PIM wiring harness routing which may be positioned very close to a high voltage or high current devices such
as aftermarket audio systems.
NOTE
High voltage or high current devices may induce
electrical noise on a circuit, which can interfere
with normal circuit operation.
• The PIM is sensitive to Electro Magnetic Interference (EMI). Check for incorrect aftermarket theft deterrent
devices, lights or mobile phone installations if an intermittent malfunction is suspected.

Communication Check Failure
Diagnostic Table
Step Action Yes No
1
Has the Diagnostic System Check been performed?
Go to Step 2 Refer to
7.2 Diagnostic System Check
2 Test the following PIM circuits for a high resistance, open circuit or
short to ground fault condition. Refer to 8A Electrical - Body and
Chassis for information on electrical diagnosis:
• 12 V battery supply circuit,
• 12 V ignition circuit, and
• ground circuit.
Has any fault been found and rectified? Go to Step 10 Go to Step 3
3 1 Disconnect the ECM harness connector.
2 Switch off the ignition for 10 seconds.
3 Using Tech 2, attempt to communicate with the PIM.
NOTE
Other DTCs may set when the ECM connector is
disconnected and the ignition is switched on. Disregard
DTCs that set under this condition on this DTC Table.
Does Tech 2 communicate with the PIM? Go to Step 4 For vehicles with
automatic
transmissions, go to
Step 5. For vehicles with manual
transmission go to Step 8
4 Replace the ECM. Refer to 6C1-3 Engine Management – V6 –
Service Operations.
Has the repair been completed? Go to Step 10 —
5 1 Disconnect the TCM harness connector.
2 Switch off the ignition for 10 seconds.
3 Using Tech 2, attempt to communicate with the PIM.
Does Tech 2 communicate with the PIM? Go to Step 6 Go to Step 8
6 Test serial data circuits between the TCM and ECM for a short to
voltage, short to ground or short together condition.
Has any fault been found and rectified? Go to Step 10 Go to Step 7
7 Replace the TCM. Refer to 7C4 Automatic Transmission – 4L60E –
On-vehicle Servicing.
Has the repair been completed? Go to Step 10 —
8 Test serial data circuits between the PIM and ECM for vehicles with
manual transmission, or between the PIM and TCM for vehicles with
automatic transmission for a high resistance or open circuit fault
condition. Refer to 8A Electrical - Body and Chassis for information on
wiring circuit testing and repair.
Has any fault been found and rectified? Go to Step 10 Go to Step 9
9 Replace the PIM. Refer to 11.2 Powertrain Interface Module.
Has the repair been completed? Go to Step 10 —
10 Using Tech 2, attempt to communicate with the PIM.
Does Tech 2 communicate with the PIM? Go to Step 11 Refer to
7.2 Diagnostic System Check

9 DTC Tables
9.1 DTC C0550 – PIM Internal Fault
DTC Description
This diagnostic procedure supports the following DTCs:
• DTC C0550 – EEPROM Error.
• DTC C0550 – Internal Control Module Read Only Memory (ROM Error).
• DTC C0550 – Internal Control Module Random Access Memory (RAM) Error.
Circuit Description
The powertrain interface module (PIM) is the control centre for the communication language conversion between GM
LAN serial data and keyword 2000 serial data. If there is an internal microprocessor integrity fault condition with the PIM,
DTC C0550 will set.
Additional Information
• Refer to 6 W iring Diagram and Connector Chart for the following information:
• PIM connector illustration and terminal assignment, and
• PIM wiring diagram.
• For intermittent fault conditions, refer to Intermittent Fault Conditions.
• Since fault conditions in a wiring connector may trigger DTCs, always test the connectors related to this diagnostic
procedure for shorted terminals or poor wiring connection before replacing any component. Refer to 8A Electrical -
Body and Chassis for information on electrical fault diagnosis.
Conditions for Running the DTC
• Conditions for running the DTC are:
• The ignition is switched on.
• The ignition voltage is 10.0 – 16.0 V.
Conditions for Setting the DTC
An internal PIM fault exists.
Action Taken When the DTC Sets
The action taken when any of these DTCs set will depend on the severity of the error. This may vary from no visual or
audible warnings to a Malfunction Indicator Lamp and / or Service Vehicle Soon warning lamp displayed on the
instrument cluster.
Conditions for Clearing the DTC
Refer to 4.1 Diagnostic General Descriptions for information on the conditions for clearing DTCs.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 This step checks if the DTC is current, and if so, indicates the PIM has an internal problem.
3 This step checks the PIM ground and 12 V battery supply.
