1 Purpose
The purpose of this supplement is to provide information on the HSV electrical and instrument accessories fitted to the
HSV W K model. The information is designed to supplement that given in the Holden W K Service Information and details
are given where differences occur between the HSV models, and standard Holden models. A series of instruction
drawings describe the design changes and indicate specific part numbers, fitting instructions and relevant notes for
vehicle servicing.
NOTE
If specific technical data on a HSV model is not
contained in this supplement, obtain data for that
model from the Holden WK Service Information.
References are made throughout this section to
Holden Service Information, to assist in providing
information for specific service operations.
When hoisting (or jacking) HSV models,

2.2 Service Operations
The HSV instrument cluster and the standard Holden WK cluster use the same mounting fixtures and fasteners.
Remove, service and refit the HSV instrument cluster in accordance with the procedures detailed in the WK Service
Information.
Electrical Facilit ies
The various special HSV options fitted to the WK vehicles often require that special or additional electric harnesses be
installed. Some of these HSV harnesses are fitted during vehicle build-up at the Holden factory and other smaller
harnesses (often called ‘a patch harness’) are fitted at the HSV facility when the electrical option is being installed. A
summary of these electrical harnesses is included to facilitate service, repair and retro-fitment of the HSV options.

3 HSV Embedded Securit y Sys tem
3.1 General Information
The new HSV Embedded Security System (ESS) is fitted as standard equipment to all HSV VTII, WH, VY and WK model
Vehicles. The ESS is a microprocessor-controlled immobiliser, which automatically interrupts essential electrical circuits
when in “armed mode”. The ESS stores the BCM’s security code and when the car is started it reads this code from the
SCI bus. If this code is different from the stored one the ESS enters armed mode and prevents the vehicle from starting.
Electri cal and Instruments Page I-6
Page I-6
3.2 Linking The ESS To A New BCM At The
Retailer – BCM In Warranty
If the BCM requires replacement within the BCM warranty period, the Retailer shall be supplied with a replacement BCM
programmed with the same BCM security code as the original BCM. In this case, the replacement BCM and new keys
are simply fitted to the vehicle. No ESS specific requirements are needed.
Electri cal and Instruments Page I-7
Page I-7
3.3 Linking The ESS To A New BCM At The
Retailer – BCM Out Of Warranty
When a BCM requires replacement outside the BCM warranty period the Retailer shall need to obtain a replacement
BCM and keys from Holden’s Service Parts Operation (HSPO). The replacement BCM and Keys will not contain the
same BCM Security Code as the original BCM.
When a new BCM with different BCM security code is fitted to the vehicle, the Retailer will have to do the following:
- Program a new key to the BCM.
- Link the BCM and PCM.
TECH 2 must be connected to the vehicle diagnostic connector whils t the key is being programmed and/or ESS is being
linked to the vehicle. The Link Enable Procedure is required to be performed twice to allow an all new key to be
programmed and also allow the ESS learn to learn the BCM security code. The procedure for programming a new key to
a new BCM and linking the ESS to the vehicle is as follows:
1. Fit new BCM to the vehicle.
2. Ensure all doors, boot and bonnet are closed, all doors are unlocked, dome lamp is in the ‘doors’ position and the
radio, headlight and wash-wipe switches are off.
3. Place new key into the ignition barrel.
4. Turn ignition on. Verify ESS beeps 5 times.
5. For VT.II / VX Vehicles TECH2 must be operating in the “Normal Mode” submenu of the Body Control Module
sub-menu.
For VY / WK Vehicles TECH2 must be operating in the Body Control Module sub-menu only.
6. Perform the Link Enable Procedure (see Section 3.5). Wait 1 second between each lock unlock to ensure the
door lock actuators function correctly during this procedure.
7. Verify that the ESS beeps twice. TECH2 reports ignition is at 12VDC. The ESS has now entered “Key
Programming mode”.
8. Select Key Programming function – “All New Key” - from the security sub-menu in the body menu of the TECH2.
Enter BCM security code as requested by TECH2. Complete key programming as requested by TECH2.
9. Turn ignition off and wait for 2 seconds. Turn ignition on.
10. Verify ESS beeps 5 times. (At this stage the ESS is in “armed mode”).
11. For VT.II / VX Vehicles TECH2 must be operating in the “Normal Mode” submenu of the Body Control Module
sub-menu.
For VY / WK Vehicles TECH2 must be operating in the Body Control Module sub-menu only.
12. Perform the Link Enable Procedure (see Section 3.5). Wait 1 second between each lock unlock to ensure the
door lock actuators function correctly during this procedure.
13. Verify that the ESS beeps twice. TECH2 reports ignition is at 12Vdc.
14. Link the PCM to the BCM using TECH2. ESS beeps twice (ESS has now learned the BCM security code).
15. Turn ignition off. Wait until TECH2 programming is co mpl ete .
16. Turn ignition on.
17. Turn ignition off. Wait 2 seconds.
18. Turn ignition on.
19. Verify ESS beeps once. The ESS is now operating in “normal mode”.
20. Crank engine. Verify vehicle starts as normal.
Electri cal and Instruments Page I-8
Page I-8
3.4 Key Programming Mode
Once the ESS has been placed into key programming mode the ESS will behave as if in “sleep mode” for one ignition
cycle only. This allows for the one ignition cycle that is required to program a new key to a new or existing BCM. The
ESS will enter “normal mode” for the next ignition cycle. If the BCM is a new BCM in the vehicle with a new security
code, the ESS will then enter “armed mode” as expected.
Programming Extra Keys To The Vehicle
Programming more keys for the vehicle can be achieved using TECH2 once the ESS has been re-linked to the vehicle
as described as follows:
1. Ensure all doors, boot and bonnet are closed, all doors are unlocked, dome lamp is in the ‘doors’ position and the
radio, headlight and wash-wipe switches are off.
2. Place new key into the ignition barrel.
3. Turn ignition on. Verify ESS beeps 5 times.
4. For VT.II / VX Vehicles TECH2 must be operating in the “Normal Mode” submenu of the Body Control Module
sub-menu.
For VY / WK Vehicles TECH2 must be operating in the Body Control Module sub-menu only.
5. Perform the Link Enable Procedure (see Section 3.5). Wait 1 second between each lock unlock to ensure the
door lock actuators function correctly during this procedure.
6. Verify that the ESS beeps twice. TECH2 reports ignition is at 12Vdc. The ESS has now entered “Key
Programming mode”.
7. Select Key Programming function – “Extra Key” - from the security sub-menu in the body menu of the TECH2.
When TECH2 requests ignition to be cycled with the existing key, leave the new key in the ignition barrel and
instead, press the unlock button on the existing key. Verify the ESS beeps once and the Theft Deterrent LED
stops flashing. Complete key programming as requested by TECH2.
8. Turn ignition off and wait for 2 seconds.
9. Turn ignition on. Verify ESS beeps once. The ESS is now operating in “normal mode”.
10. Crank engine. Verify vehicle starts as normal.

4 Electro-Chromatic Mirrors
4.1 General Information
Electro-chromatic mirrors are standard fitment in all New Zealand WK Grange vehicles. The mirror features an electronically
controlled mirror cell which changes colour in response to an applied electrical voltage. This allows automatic darkening of
the mirror during night driving when the headlamps of a following vehicle shine on an integrated light sensor. This function
only operates when the integral sensor detects low ambient (i.e. at night time). The mirror operates automatically, however,
an AUTO/MANUAL switch provides the driver with the option for the mirror to be darkened during low ambient light
conditions regardless of presence or absence of following headlamps. When reverse gear is selected, the mirror
automatically lightens.
