NOTE
The Tech 2 PIM Security Information Data List
typical display values are obtained from a
correctly operating vehicle under the following
conditions:
• ignition switched on,
• engine not running, and
• vehicle is stationary.
Tech 2 Parameter Units Displayed Typical Display Values
ICU / PIM Status Yes / No Yes
Security Code Programmed Yes / No Yes
Security W ait Time Inactive / Active Inactive

12.2 PIM Reset Procedure

Do not perform the reset procedure within
sixty seconds of turning the ignition switch
on. Failure to comply may result in the PIM
failing to reset.
W hen a PIM has been installed into a vehicle, it is security linked to the immobiliser control unit (ICU) and engine control
module (ECM). Once this linking has been performed, the PIM cannot be installed in any other vehicle, unless the
security linking between the ICU and the ECM has been reset using the following procedure:
1 Prior to resetting the PIM, obtain the Security Code. For further information, refer to 12.1 Security and Programming Information.
2 Connect Tech 2 to the data link connector (DLC) and turn the ignition switch on.
3 On Tech 2 select: Body / Powertrain Interface Module / Security / Reset PIM .
NOTE
When Tech 2 requests programming approval,
obtain TIS approval.
NOTE
If a Tech 2 screen displaying Security Wait Time
Active, Please Wait! appears after selecting the
Reset PIM option, an incorrect security code has
been previously entered. Refer to 12.1
Security and Programming Information for further
information.
4 W hen Tech 2 displays Enter Security Code, enter the security code, press the Enter key and then the Okay soft
key.

The engine will not start after the PIM has
been reset.
5 W hen Tech 2 displays Do you really want to Reset? , press the Reset soft key.

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.

Programming
If Programming is selected, a selection list is displayed which contains:
• Reset TAP Cells – This test allows the user to reset the Transmission Adapt (TAP) cells by pressing the Reset soft
key.
NOTE
Upon resetting the TAP cells the TCM loses all
learnt adaptive functions. When the vehicle is first
driven after this, the shifts may be harsh. This
harshness will ease as the TCM relearns the TAP
cells.

Automatic Transmission – 4L60E – Electrical Diagnosis Page 7C2–50
Action Taken When the DTC Sets
• The TCM illuminates the MIL during the second consecutive trip in which the Conditions for Setting the DTC are
met.
• The TCM commands maximum line pressure.
• The TCM freezes transmission adaptive functions.
• The TCM calculates vehicle speed from the automatic transmission engine r.p.m. and commanded gear.
• At the time of the first failure, the TCM records the operating conditions when the conditions for setting the DTC are
met. The TCM stores this information as a Failure Record.
• At the time of the second failure, the ECM records the operating conditions when the conditions for setting the DTC
are met. The ECM stores this information as a Freeze Frame.
• The TCM stores DTC P0722 in TCM history.
Conditions for Clearing the DTC
• The ECM turns off the MIL after the sixth consecutive drive trip in which the TCM does not send a MIL illumination
request.
• Tech 2 can clear the DTC.
• The TCM clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without an emission related
diagnostic fault occurring.
• The TCM cancels the default actions when the ignition is off long enough to power down the TCM.
Diagnostic Aids
• Inspect the rear internal gear teeth for damage.
• Visually inspect the VSS for cracks or damage.
• Ensure the VSS is properly torqued to the extension housing.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Disable the traction control system when performing this step. W hen the ignition key is cycled off and then cycled back on, the traction control system defaults to on.
3 Checks the VSS for correct resistance.
4 Checks if the VSS and associated circuits are shorted to ground.
5 Checks the VSS produces an AC voltage when the output shaft is rotated.
6 Checks the integrity of the circuits between the TCM and the VSS.
