13.5 Security
F0: Immobiliser Link To ECM/PIM
Should the ECM, PIM or ICU be replaced, the modules must be security linked to each other. If this linking
procedure is not performed, the vehicle will not crank nor run. For additional information relating to Tech 2
and the linking procedure, refer to 11A – Immobiliser.
NOTE
After an ECU reset, the ignition switch must be
turned Off for at least 10 seconds and then
turned On for at least one minute, before
attempting communication between Tech 2 and
the ECU.
Preconditions: TIS approval (TIS 2000 Security Access) must be obtained, the four digit security number
entered into Tech 2 and the theft deterrent system disarmed. Then the ignition must be turned ‘On’, using a
programmed remote coded key.
F1: Reset PIM
This function erases the security link between the Engine Control Module (ECM) and the Powertrain Interface Modules (PIM). If this procedure is performed, the engine will not crank nor run. A ICU Link to ECM/PIM
procedure will need to be performed. For additional information relating to the ICU Link to ECM/PIM
procedure, refer to 11A – Immobiliser.
NOTE
After an ECU reset, the ignition switch must be
turned Off for at least 10 seconds and then
turned On for at least one minute, before
attempting communication between Tech 2 and
the ECU.
Preconditions: The four digit security code must be entered into Tech 2 and the ignition switched ‘On’ with a
programmed remote coded key.
F2: Security Information
The security code is required when performing certain PIM, ICU and ECM programming functions. W hen Tech 2 requests the security code to be entered, and an incorrect code is entered, the PIM will go into a
security wait time stage. This wait time stage will prevent any further attempts to enter the security code until
the wait time has elapsed.
Should a second incorrect security code be entered after the initial wait time has elapsed, the PIM will go into a second wait time stage. The wait time will increase each time an incorrect code is entered. W hen the
correct code is entered the wait time will reset back to its original value of 10 seconds.
NOTE
The ignition switch must be in the ON position
with the battery connected during the wait time
period.
The wait time stages are as follows: • Stage 1 = 10 seconds.
• Stage 2 = 10 seconds.
• Stage 3 = 10 minutes.
• Stage 4 = 20 minutes.
• Stage 5 = 40 minutes.
• Stage 5 = 80 minutes.

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.

1.2 7C1 Automatic Transmission – 4L60E –
General Information
This section provides general information about the automatic transmission, including:
• A glossary of terms,
• Transmission identification information,
• Electrical overview of the Transmission Control Module (TCM),
• Some notes that address safe workshop practices,
• Service notes relating to fasteners and consumable items used at various stages throughout this section,
• Special tools required to work on the transmission,
• Fastener torque specifications, and

For all information relating to the mechanical construction and function of the 4L60E automatic transmission, refer to the
General Motors Powertrain Group Electronically Controlled Automatic Transmission Technician’s Guide.
This guide includes such information as:
• Transmission Cutaway Views,
• Principles of Operation,
• Power Flow,
• Complete Hydraulic Circuits,
• Bushing and Bearing Locations,
• Seal Locations and
• Illustrated Parts List.
NOTE
Specifications quoted in this General Motors
Powertrain Group Electronically Controlled
Automatic Transmission Technician Guide may
not be for the vehicle you are working on. For
correct specifications refer to
7 Transmission Specifications.
Recommendations
When servicing the transmission, all parts should be cleaned and inspected. Individual units should be reassembled
before disassembly of other units to avoid confusion and interchanging of parts.
a Thoroughly clean the transmission exterior before removal of any component.
b Disassembly and reassembly must be made on a clean work bench. Cleanliness is of the utmost importance, the bench tools and parts must be kept clean at all times.
c Before installing screws and other fasteners into aluminium parts, dip screw threads into transmission fluid to prevent galling aluminium threads and to prevent screws from seizing.
d To prevent thread stripping, always use a torque wrench when installing screws or nuts.
e If threads in aluminium parts are stripped or damaged, the parts can be made serviceable by the use of commercially available thread inserts.
f Protective tools must be used when assembling seals to prevent damage. The slightest flaw in the sealing surface of the seal can cause an oil leak.
g Aluminium castings and valve parts are very susceptible to nicks, burrs, etc. and should be handled with care.
h Expand Internal snap rings and compress external snap rings if they are to be re-used to ensure proper seating when reinstalled.
i Do not re-use removed O-rings, gaskets and oil seals.
j Teflon oil seal rings should not be removed unless damaged.
k During assembly of each unit, all internal moving parts must be lubricated with transmission fluid.
Oil Cooler Pipes
Should any transmission fluid cooling pipe suffer accidental damage, a genuine replacement pipe must be fitted. Refer to
the current release of PartFinder™ to determine the correct part number for the particular engine and pipe involved.
Reworking of damaged pipes or hand made replacements are not permitted.
