11 Service Operations
11.1 Safety and Precautionary Measures

The following safety and precautionary
measures must be followed when servicing
and diagnosing the powertrain interface
module (PIM) System. Otherwise, personal
injury and / or improper braking system
operation may occur:
• W hen using electric welding equipment, disconnect the wiring harness connector from the PIM.
• Never disconnect or reconnect the PIM wiring harness connector when the ignition is switched ON.
• Do not touch the PIM connector pins or soldered components on the PIM circuit board to prevent possible
Electrostatic Discharge damage.
• To avoid wiring connector terminal damage, always use suitable wiring harness test leads (such as those in Tool
No, J35616) when performing tests on the PIM wiring connector.
• The PIM is extremely sensitive to Electro Magnetic Interference (EMI). Ensure the PIM wiring harness is routed
correctly and securely fitted to mounting clips when performing service procedures.
• Due to the sensitive nature of the PIM circuitry, specific wiring repair procedures have been developed. These
procedures and instructions are detailed in 8A Electrical - Body and Chassis and are the only recommended and
approved wiring repair methods.
• Ensure that all wiring harness connectors are seated correctly.
• Never disconnect the battery from the vehicle electrical system while the engine is running.
• Always disconnect the battery from the vehicle electrical system before charging.
• Do not use a fast charger for starting the vehicle.
• Ensure the battery cable terminals are secure.
• Before installing a new PIM, ensure the correct type is fitted. Always refer to the latest spare parts information.
11.2 Powertrain Interface Module

Do not touch the powertrain interface module
pins as Electrostatic Discharge (ESD) damage
may result. For further information on ESD,
refer to 1.2 Warning Caution and Notes.

When replacing the PIM, the PIM must be
reset prior to removal. Failure to perform this
procedure will result in the inability to:
• Test the PIM for warranty purposes.
• Install the PIM into other vehicles.

Service Notes
1. Vehicles fitted with catalytic converters should not be operated with leaded petrol. Lead will contaminate
the ceramic monolith.
2. Do not drop the catalytic converter as it will damage the ceramic monolith.
3. Replace the catalytic converter if it is damaged.
4. Do not allow water, oil or fuel to enter the converter as the ceramic monolith will be contaminated.
5. Do not use engine and/or fuel additives unless approved by General Motors. Many additives contain phosphorous that will contaminate the ceramic monolith.
6. The vehicle must not be started by pushing or towing, as unburned fuel could reach the catalytic converter and destroy the ceramic monolith. Always use jumper leads to start a vehicle that has a flat or
defective battery.
7. W hen carrying out a compression test, for V6 engines use Tech 2 to ensure the output control Engine Compression Test is set to enable, refer to 6A1 Engine Mechanical. This prevents fuel injection and
ignition during engine cranking.
8. Do not drive the vehicle with the engine misfiring or with any of the spark plug leads disconnected, as the catalytic converter will overheat.
9. Do not coast downhill with the engine misfiring or with any of the spark plug leads disconnected.
10. The catalytic converter is serviceable as part of the front exhaust assembly only. Refer to the service operations in this section for details of front exhaust pipe assembly removal and reinstallation.
11. The exhaust flange gaskets must be replaced whenever a new exhaust pipe, muffler or catalytic converter is installed.
1.3 WARNING, CAUTION and NOTES
This Section contains various W ARNINGS, CAUTIONS and NOTE statements that you must observe carefully to reduce
the risk of death or injury during service, repair procedures or vehicle operation. Incorrect service or repair procedures
may damage the vehicle or cause operational faults. W ARNINGS, CAUTION and NOTE statements are not exhaustive.
HOLDEN LTD can not possibly warn of all the potentially hazardous consequences of failure to follow these instructions.
1.1 Definition of WARNING, CAUTION and NOTE Statements

Diagnosis and repair procedures in this Section contain both general and specific W ARNING, CAUTION and NOTE
statements. HOLDEN LTD is dedicated to the presentation of service information that helps the technician to diagnose
and repair the systems necessary for proper operation of the vehicle. Certain procedures may present a hazard to the
technician if they are not followed in the recommended manner. W ARNING, CAUTION and NOTE statements are
designed to help prevent these hazards from occurring, but not all hazards can be foreseen.
WARNING defined
A W ARNING statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in death or injury. A W ARNING statement alerts you to take necessary action or not to take a
prohibited action. If a W ARNING statement is ignored, the following consequences may occur:
• Death or injury to the technician or other personnel working on the vehicle,
• Death or injury to other people in or near the workplace area, and / or
• Death or injury to the driver / or passenger(s) of the vehicle or other people, if the vehicle has been improperly
repaired.
CAUTION defined
A CAUTION statement immediately precedes an operating procedure or maintenance practice which, if not correctly
followed, could result in damage to or destruction of equipment, or corruption of data. If a CAUTION statement is
ignored, the following consequences may occur:
• Damage to the vehicle,
• Unnecessary vehicle repairs or component replacement,
