Wiring Harnesses - Wiring Harness
Description and Operation
Introduction Published: 21-Jan-2014
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. Repairs may only be made to cables and connectors which have been mechanically, not electrically damaged. It also
applies where the whole extent of the damage can be clearly identified and rectified.
Care and neatness are essential requirements in making a perfect repair.
Caution:
This harness repair guide, does not approve repairs to any of the following circuits:
1. Any media orientated system transport network harnesses.
2. Supplement restraint system (SRS) firing circuits (Air bags).
3. 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. 4. Screened cables, leads and wiring harness(s).
If any harness(s) with defective electrical connector terminals or wires from the above circuits are a concern, new
components must be installed.
Repair Components
CAUTION: 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.
The wiring harness repair components 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
A suitable heat source, for shrinking heat shrink sleeves will be required.
The pre-insulated diamond grip range of electrical connector terminals and in-line, butt splice connectors are the only
acceptable product for the repairs of wiring harnesses. The butt connectors not only grip the wire but also the insulation,
making a very secure joint.
If an electrical connector terminal is not available approval for the repair is NOT given and in these circumstances a new wiring
harness must be installed.
Pre-Terminated Wiring Harness(s) and Butt Splice Connectors
The pre-terminated wiring harness(s) are supplied with the insulation in one of three colors, red, blue or yellow. The colors do
not apply to any particular circuit but to the harness wire size. See the Relationship Table in the Repair Method section.
Butt splice connectors are also supplied with red, blue or yellow coverings, which must be matched to the pre-terminated
wiring harness insulation color.
Check the Starter Relay circuit.
NOTE: On petrol engine variants, due to Smart Start, both sides of Relay Coil are switched directly from ECM (If
conditions correct). On diesel engine variants the low side only is switched directly from the ECM.
Check that the Steering Column Lock correctly operates and the steering wheel can turn freely.
Check that the High Speed CAN network is not malfunctioning, i.e. the CAN circuit is open or short circuit. This would mean
that the instrument cluster and ECM would be unable to communicate resulting in no Challenge being performed to enable the
ECM. This would be supported by LED Flash Code 24, see PATS Fault Code Table.
Also check the CAN network between the ABS module and the CJB. The CJB uses the CAN_BrakePressureTMC signal to
determine if the brake pedal has been pressed in order to allow an engine crank. The CJB uses a value of 0x05, if the CJB sees
a value less than this, it will not enable the Crank Request Output.
Engine cranks but will not start
If the Engine is cranking it means that the ECM has passed the authorisation required with the Instrument Cluster. If this
authorisation failed, the ECM would not engage the starter relay. This could be confirmed by verifying the PATS LED prove out
(illuminated solid for 3 seconds) or by reading DTCs from the instrument cluster and ECM.
In this case, the fuel pump circuit should be verified. The Fuel Pump Delivery Module (FPDM), which is supplied via the RJB
(authentication required with the instrument cluster) and controlled by the ECM, supplies the fuel pump.
In all cases of suspected non-start issues, the most logical failure modes should be eliminated first. i.e.
1. Check all relevant supplies and grounds to the relevant modules listed herein.
2. Note any unusual behaviour from other systems/functionality.
3. Note any functions that are not operating as expected.
PATS Fault Codes
For the various PATS modes/faults listed in the table , the instrument cluster will store a DTC and indicate this to the customer
during the detection period defined in the 'when logged' column, by illuminating the indicator as described for 60 seconds and
then flashing the LED 10 times as appropriate. The indication will stop immediately the ignition status is set to OFF any time
during the fault indication sequence. Up to 4 DTCs could be stored per key read sequence (1-10 read attempts). No DTCs will be
stored until all retry attempts are complete. Only the highest priority fault code will be flashed.
To determine the fault code from the LED: The LED will flash initially ten times with 1.5 seconds between. The LED will remain
OFF for 2.5 seconds then flash a number of times with 0.5 seconds between (the number of times the LED flashes represents
the first digit of the code), the LED will remain OFF for 1.5 seconds then flash a number of times with 1.5 seconds between
(the number of times the LED flashes represents the second digit of the code).
The PATS LED will be commanded on as shown under 'indication'. Normal PATS operations are complete within 400ms of the
ignition switch transition from OFF to ON or START, worst case for ECM communication problems will be less than 2 seconds. If
PATS is not complete during the 2 seconds the ECM will terminate PATS and await the next ignition ON or START event. PATS
faults will be indicated via the LED as soon as possible and will terminate the LED prove out. At ignition OFF all previous
flashing will cease and the perimeter anti-theft system will control the LED when the vehicle is locked and armed.

supplies provide power for the movement motors in addition to the driver's seat switch pack. Power is only supplied to the
driver's seat module and the driver's seat switch pack when the ignition is on (power mode 6).
The driver's seat switch pack is connected to the driver's seat module by a LIN bus for the seat movement switches. Any selection for seat movement generates a message which is passed via the LIN to the driver's seat module. The seat module processes the request and operates the applicable seat function as required using the power supplies from the CJB.
Each seat motor contains a Hall position sensor. The sensor sends a feedback signal to the driver's seat module. The signal is
used for memory store and memory recall functions.
The lumbar adjustment switch on the driver's seat switch pack is wired direct to the lumbar pump and solenoids. The switch,
when moved to the inflate position for either the upper or lower inflatable cushion cell, provides a power supply to the lumbar
pump and simultaneously activates the applicable inflate solenoid valve. When the switch is released the pump stops and the
solenoid valve closes trapping the air in the inflatable cushion. When the switch is moved to the deflate position for either the
upper or lower inflatable cushion cell, power is supplied to the applicable deflate solenoid valve which opens to allow the air in
the cushion to escape. When the switch is released, the valve is closed and the remaining air in the cushion is retained.
FRONT SEATS - DESCRIPTION Component Description
The table below highlights the features available for each seating option.
Seat Type Non-Heated Heated Heated and Cooled Lumbar Support Memory 8-way Yes Optional No 2-way No 10-way Yes Optional Optional 2-way Optional (Driver's seat only) 12-way No No Yes 4-way No 16-way No No Yes 4-way Yes (Driver's seat only) Seat Heating
The 3-stage heated front seats feature 2 heater elements located in the seat cushion and a single heater element located in
the seat squab. Operation of the heated front seats is controlled by the ATC module via the TSD, information and entertainment control module and the CJB module on vehicles with heated seats. On vehicles with heated and cooled seats the operation is controlled by the TSD, information and entertainment control module and the front seat climate control
module.
The heated and cooled front seats each contain 2 climate modules; one in the cushion, one in the squab. The climate modules
contain 'Peltier' cells which are able to deliver heating and cooling based on a voltage provided by the front seat climate
control module. Each climate module also contains a fan, which blows air over the Peltier cells to distribute heated or cooled
air via liners in the seat cushion and squab. The fan is also controlled by the front seat climate control module. The TSD allows
the driver and passenger to select 3 ranges of heated or cooled ventilation; off, minimum and intermediate. Also, using the
selections on the TSD, the driver and passenger can select between full seat ventilation or squab backrest ventilation only.
Vehicles fitted with the 3-stage heated front seat option also feature a heated steering wheel.
Refer to: Steering Column Switches (211-05 Steering Column Switches, Description and Operation).
Electric Seat Adjustment
Lumbar Support
On 8, 10 and 12 way seats, a 2 way lumbar support is provided which allows the lumbar inflatable cushion to be inflated or
deflated as required. On 16 way seats, a 4 way lumbar support is fitted which comprises two separate cushion cells. The upper
and lower cells can be inflated or deflated individually allowing greater comfort adjustment for the driver and passenger.
The lumbar support comprises an inflatable cushion located in the seat squab, a pump and solenoids. The pump is activated
when the applicable seat switch is moved to the inflate position, inflating the cell(s) in the inflatable cushion. On 8 and 10
way seats, a single solenoid operated valve allows the inflatable cushion to be deflated. On 12 and 16 way seats, 4 solenoid
valves control the inflation and deflation of the upper and lower inflatable cushion cells, allowing each cell to be adjusted
individually.
Seat Motors
The head restraint motor is located in the upper section of each seat squab and is accessible by removal of the seat back. The
motor moves a cradle which is driven in a vertical motion by a rack and pinion arrangement. The cradle has the two head
restraint stems attached to it and therefore raises and lowers the head restraint as the motor moves the cradle. The motor
contains a Hall sensor which supplies positional information to the driver's seat module.
The seat slide motor is an integral component of the seat frame. The motor drives on a gear on a worm drive lead screw which
is integral with the floor rail. The lead screw has a stop at each end to limit the fore and aft seat movement.
