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.

Tech 2 PIM Security Information Data List
The Tech 2 PIM Security Information Data List displays the PIM's current security status.
To view the data list:
1 Connect Tech 2 to the data link connector (DLC) and turn the ignition switch on.
2 On Tech 2 select: Body / Powertrain Interface Module / Security / Security Information .
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.

Exhaust System – V6 Page 6F – 2

1 General Information
Information contained within this section describes the general exhaust system.
1.1 Emission Reductions
Through developments in various vehicle emissions reduction systems, significant reductions in emissions have been
achieved. The developments have been primarily concerned with refinements in engine calibration and the optimisation
of exhaust system catalytic converter configurations.
The catalytic converter is similar to a muffler in appearance
however, within the outer stainless steel shell (4), there is a
ceramic monolith (1) which is honeycombed in the direction
of exhaust flow, as shown. The ceramic monolith is
surrounded by a mat (2), which has the primary function of
holding the monolith firmly in place to prevent any contact
with the inner shell (3). A mesh seal (5 and 6) at each end
of the converter prevents exhaust gases from fouling and
eroding the mat.
Surfaces of the ceramic monolith that are exposed to
exhaust gases are coated with a catalytic material. This
material contains rhodium and platinum, which act to
facilitate the chemical reactions necessary to oxidise carbon
monoxide and hydrocarbons into harmless carbon dioxide.
Figure 6F– 1
The catalytic converter is a substance that accelerates a chemical reaction without itself being changed. Engine exhaust
gases contain carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NO
x). W hen the exhaust gases flow
through the monolith, reactions with the catalytic converter occur. CO and HC are converted by oxidation with oxygen
(O
2) in the exhaust gases to produce carbon dioxide (CO2) and water vapour (H2O). NOx is converted by reduction with
CO to produce nitrogen (N
2) and CO2. The converter is called a three-way type because it simultaneously converts three
components of exhaust gas (CO, HC and NO
x) to harmless natural gases, refer to Figure 6F– 2
