15. 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 over tighten. 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 connector is securely held in the aperture. This will
give support to the butt connector while the pre-terminated wiring harness is inserted into it.

NOTE: See illustration: Splice Correctly Located

Insert the pre-terminated wiring harness 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 freed 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 harness(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 splice window over the guide bar. Make sure that the cable harness
wire is against 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 splice 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 until the fuel spill has fully evaporated.
CAUTIONS:


When using a heat source make sure that it is localised and causes 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 wiring harness insulation becomes damaged.
Using a suitable heat source, shrink the sleeve over the butt splice.
If further pre-terminated wiring harness(s) are to be installed to the same 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 harness 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 cover and secure with adhesive electrical tape. Do not cover the wiring harness right to the
electrical connector as the terminals must have a little movement and not 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.

1. If any unit reads greater than 10 ohms, replace only that defective unit

2. If all units read less than 10 ohms but faults are still suspected, do not replace any units. Refer to step 4 below

3. As a final check, when a faulty unit has been identified strip the seat to access unit connector, REFER to: Seats
(501-10, Removal & Installation) and re-check ohm reading to confirm greater than 10 ohms prior to removing unit

4. In cases where the above diagnostic routine does NOT identify a failed unit, please refer to "Over Temperature and
Fluid/Air Leak Diagnostics" below. Also check for any live technical service bulletins referring to the seat climate system

Seat Climate Control Module/Seat Climate Assembly - Further Diagnostics

In the event of suspected climate seat faults use the pinpoint tests detailed below
Connector Checks

First, check the integrity of the three seat climate control module harness connectors:

1. Disconnect each connector
2. Inspect each connector for cracks and breaks, replace as required

3. Check the integrity of connector terminals for bent terminals, backed-out or badly crimped wires. Rectify as required

4. Reconnect all connectors and retest. If seat climate functions are still faulty, note any DTCs that have been logged by
the seat climate control module(s) and refer to the table and pinpoint tests below:

Check For Air Flow Specific DTCs Diagnostic Guidance Notes
B120F-98
Once the diagnostic process detailed above has been carried out and it has been identified that B122E-98 there has not been a failure of any of the climate units, then refer back to the relevant climate B122F-98 system DTC codes that have been recorded B1230-98 DTC codes listed that end in 7A or 98 indicate a possible air leak or air flow restriction within the B1231-7A system B1232-7A In these circumstances, starting with the seat base check all ducting connections for correct engagement and inspect ducting for signs of damage which could result in an air leak (for connection issues re-connect and test system). Only in the event of finding damage to the ducting of one of the units should the unit be replaced. Note that only the specific unit should be replaced Due to the design function of the system, both climate units in any one seat operate integrally. Therefore, if an issue is detected in one of the units then both units are shut down to protect the system until next ignition cycle. Under these circumstances, only replace the damaged unit and DO NOT replace both units DTC Index

NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).
