Repair Procedure
• CAUTIONS: Do not use crimping pliers, insulation strippers, butt splice connectors, heat sh rink sleeves or pre-terminated wiring
harness(s) that are not supplied with the Jagu ar wiring harness repair kit. Each part has been designed to be used only with
the other parts in this wiri ng harness repair kit.
Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient heat to
the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not
over heat the glue lined heat shrink sleeve so that the wiring harness insulation becomes damaged.
It is not correct to make more than five repair joints on the wiring harness to any electrical connector and if more damage is
found at the same electrical connector then a new wiring harness must be installed.
Remove the faulty terminal from the elec trical connector using the extractor tool and correct tip. Make sure that any
anti-backout device is released befo re trying to remove the terminal.
CAUTION: : A number of electrical connector terminals ar e gold plated or gold flashed. When defective, they
must be installed with a gold pre-terminated wiring harnes s(s) from the wiring harness repair kit. It is not always
easy to identify the female as gold but the male pins are visually easier, therefore always check both male and
female terminals to identify those which are gold. Under no circumstances are gold and tin terminals to be mixed as
this will lead to early failur e of the electrical contact.
• NOTE: Never use a harness lead with a smalle r diameter than the original harness lead.
Select the correct size and ty pe of pre-terminated wiring harness and butt splice connector from the wiring harness
repair kit.
Using the wire cutter on the stripping tool, cut the pre-terminated wiring harness and the harness cable to the
required length.
• NOTE: See illustration: Stripping Insulation
From the Relationship Table, find the correct length of insulation to be stripped from the pre-terminated wiring
harness and set the adjustable cable length stop to the correct length. Place the pre-terminated wiring harness in
the wire stripper and remove the insulation.
Put the cable identification sleeve(s) on to the wiring harness with the main cable colour nearest to the terminal. During this next step do not overtighten. Place the selected butt splice connector in the crimping tool, matching the
aperture and the butt connector colours. Make sure that the window indentation in the butt connector is resting over
the guide bar on the lower jaw. Partially close the grip until the butt connec tor is securely held in the aperture. This
will give support to the butt conn ector while the pre-terminated wiring harness is inserted into it.
• NOTE: See illustration: Spice Correctly Located
Insert the pre-terminated wiring harnes s into the butt connector and make sure that the wire is against the wire
stop. Close the grip firmly, crimping the lead to the butt connector. When the handles have been completely closed
the butt connector will be fre ed from the tool as the handles are released. If the handles have not been completely
closed then the jaws will hold the butt connector and it cannot be removed from the tool until the crimp is fully made
by closing the handles completely. Make sure that the harness cable has been squarely cut and the correct length of insulation removed. If more than
one splice is needed the butt connectors must be not be crimped to the wiring harness at the same distance from
the connector. The splices must be staggered to prevent a bulk of splices in the same area of the wiring harness.
It is preferable to cover the butt splice joint with heat shrink sleeve. This is desirable not essential, except where the
electrical connector is a sealed electrical connector. Use the smaller diameter sleeve for red and blue pre-terminated
wiring harness(s) and the large diameter sleeve for the yellow pre-terminated wiring harnes s(s). It is advisable to
place the heat shrink over the completed joint but in some instances the sleeve will not pass over the terminal.
Check, and if required, place the correct size sleeve onto the harness cable or pre-terminated wiring harness before
crimping the butt splice to the wiring harness.
Place the harness cable into the butt splice with the spli ce window over the guide bar. Make sure that the cable
harness wire is agains t the stop in the butt splice, crimp the butt splice connector to the wiring harness.
Gently pull the harness cables each side of the butt sp lice to make sure that a secure joint has been made.

WARNING: Do not use a naked flame in areas where fuel or oil have been spilt. Clean the area of residual oil
and fuel and wait un til the fuel spill has fully evaporated.
• CAUTIONS:
When using a heat source make sure that it is localised and caus es no damage to surrounding materials.
Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue
lined heat shrink sleeve so that the wi ring harness insulation becomes damaged.
Using a suitable heat source, shrink the sleeve over the butt splice.
If further pre-terminated wiri ng harness(s) are to be installed to the sa me electrical connector, make sure that the
lead is cut at a different length to the previous joint. This makes sure that the splices will, where possible, be
staggered on the wiring ha rness and prevent a bulk of splices in one area.
When all of the splices have been made, fit the terminal(s) to the electrical connector, taking care that the terminals
are correctly orientated.
Install the wiring harness cove r and secure with adhesive electrical tape. Do not cove r the wiring harness right to the electrical connector as the terminals must have a little movement and no t be firmly bound to the electrical connector or wiring harness. Make sure that the cable identification sleeve(s) are showing at the wiring harness electrical
connector.

Multifunction Electronic Modules - Module Controlled Functions
Description and Operation

Body Processor Module (BPM)
ItemPart NumberDescription
1—Body Processor Module
2—Front Door Control Module
3—Rear Door Control Module
4—Roof Console Switch Module
5—Center Console Switch Module

The BPM electronically controls many vehicle functions. It responds when a switch is actuated by providing output signals to
the appropriate devices, either di rectly or indirectly via relays. In addition the BPM establishes an ISO network link with the
Security and Locking Control Module (SLC M) and utilizes the SCP network to exchange data between the body system
modules.
The following tables are publis hed for guidance purposes and only provide a rough indication of the correlation between
circuit inputs and outputs; due to the complexity and necess ary functional interaction required for the vehicle there are
many circuits where inpu ts and outputs overlap.
Malfunction of modules must always be analyzed using the PDU as recommended in Diagnosis and Testing.

The DDM is an integral part of the vehi cle security system. In conjunction with the BPM and SLCM via the SCP network, it
controls door locking, interior lighting, door window position and door mirror position. The DDM also provides an interface
via the SCP network, between the driver door switchpack and all door control modules which permits remote control of all
door window positions.
