Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the Body Pr ocessor and the multiplexed communication networks which are
associated with it, preclude the use of wo rkshop general electrical test equipment. Therefore, reference should be made to
the PDU User Guide for detail ed instructions on testing the Daytime Running Function.
The Daytime Running function is exactly the same as for the normal operation of the side lamps (or dipped beam, where
specified) in as much as the body processor drives the same lamps from the same outputs.
The body processor has been programmed to respond to an alternative set of cond itions in order to operate the lamps,
instead of waiting for a signal from the normal light switch.
The conditions which have to be set are; ignition switch se t to position II or III and sidelight switch set to OFF. The
sidelights, side marker lamps (if fitted and enabled), tail lights and number plate lights will all be switched ON.
The PDU systematically tests and analyses all functions of the daytime running lamps.
Where a fault is indicated, before replac ing a component, some basic diagnostic methods may be necessary to confirm that
connections are good and that wiring is not damaged.

Fuse Boxes and Relays (LH Steering)

Parts List
There are six fuse box assemblies per vehicle, five of which have conventional, replaceable fuses. The High Power Protection
Module does not have conventional fuses, it comprises three 250 Amp fusible links to protect the starting circuit (two
connected in parallel) and the battery positive supply to the other fuse boxes.

Wiring Harnesses - Wiring Harness
Description and Operation
Introduction
CAUTION: Do not use any other heat shrink sleeve other than the approved glue lined heat shrink sleeve mentioned
in the repair procedure.
The purpose of this document is to promote quick and efficient minor repair to harness connectors or cables using approved
methods and the wiring harness repair kit. Repairs may only be made to cables and connectors which have been
mechanically, not electrically damaged. It also applies wher e the whole extent of the damage can be clearly identified and
rectified.
Care and neatness are essential requir ements in making a perfect repair.
Caution:
At the time of this first issue of the Harness Repair Guide, do not approve re pairs to any of the following circuits:
Any media orientated system transport network harnesses. Supplement restraint system (SRS) firing circuits (Air bags). Link lead assembles, which are unique to safety critical circuits such as anti-lock brake system (ABS) and
thermocouple circuits. An example of this is the ABS wheel speed sensors with moulded connectors.
4. Screened cables, leads and wiring harness(s).
If any harness(s) with defective electrical connector te rminals or wires from the above circuits are a concern,
new components must be installed.
Repair Kit
CAUTION: Where the repair procedure indica tes 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.
The wiring harness repair kit has been produced which comprises:
Pre-terminated wiring harness(s) of different sizes and types Three sizes of butt splice connectors A selection of colored cable identification sleeves Two sizes of glue lined heat shrink sleeves Crimping pliers A wire cutter and insulation stripper An electrical connector terminal extraction handle and tips
A suitable heat source, fo r shrinking heat shrink sleeves will be required.
The pre-insulated diamond grip range of el ectrical connector terminals and in-line, butt splice connectors contained within
the wiring harness repair kit are the only acceptable product for the repairs of wi ring harnesses. The butt connectors not
only grip the wire but also the insu lation, making a very secure joint.
If an electrical connector terminal is not included in the wiring harness repair kit then approval for the repair is NOT given
and in these circumstances a new wi ring harness must be installed.
Pre-Terminated Wiring Harness( s) and Butt Splice Connectors
All pre-terminated wiring harness(s) and butt splice connectors in the wiring harness repair kit are contained in bags which
can be resealed after use. Each bag is marked with the part number of the items stored within the bag. Each storage
compartment in the wiring harness repair kit is identified with the corresponding part number. Make sure that pre-
terminated wiring harness(s) and connectors are not mixed up it is advisable to only open one bag at a time and to reseal

The part number of the pre-terminated wiring harness The letter showing the extractor tip which must be used to remove this type of electrical connector terminal Those electrical connector terminals which are gold
Some of the pre-terminated wiring harness( s) have seals installed to the insulation for sealed connector applications. It is
essential for prevention of mo isture ingress that a sealed pre-terminated wiring harness must be used where a sealed
terminal was removed.
CAUTION: Where the repair procedure indica tes 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.
Two sizes of heat shrink sleeving are supplied in the wiring harn ess repair kit. Each heat shrink sleeve contains a sealant
glue. These must be used when connecting wiring harness(s) or electrical connector terminal(s) at all times. The smaller
diameter heat shrink sleeve is to be used with the red and blue butt splice connectors and the larger di ameter sleeve with
the yellow butt sp lice connectors.
For ease and speed, some of the pre-term inated wiring harness(s) may already have the insulation partly stripped at the
splice end. If the repair requires insula tion to be stripped from the cable, refer to the Relationship Table fo r the correct
length of insulation to be stripped.
The Pre-Terminated Wiring Harness(s) illu stration shows the electrical connector terminal type, the part number of the pre-
terminated wiring harness and the letter of the extractor tip which must be used to extract the electrical connector terminal
from the connector housing. Additionally, those electrical conne ctor terminal(s) which are gold are identified, all others are
therefore, tinned and not gold.
Wiring Harness Cable Identification Sleeves
A selection of colored sleeves are contai ned in the wiring harness repair kit for maintaining the wiring harness cable
identification on the pre-term inated wiring harness. Place the correct colo red sleeve(s) over the pre-terminated wiring
harness insulation as near to the electr ical connector as possible with the main wiring harness cable color nearest to the
electrical connector.
For example, if the original wiring harness cable color is pink with a black trace put the pink wiring harness cable
identification sleeve on the pre-terminated wiring harness first followed by a black sleeve, and slide both along the wiring
harness cable to the electr ical connector terminal.
Extraction Handle and Tips
The extraction handle, in conjunction with th e correct tip, is used to remove a terminal from an elec trical connector. Each tip contained in the wiring harness repair kit is marked with an identification letter, A to K inclusive. Each tip has been special ly
designed to extract a particular ty pe of electrical connector terminal. The use of any other tool is not recommended and is
liable to cause damage to the electrical connector. The tip is fastened to the handle by a screw which holds the tip firmly yet
allows it to be easily replaced.
