Seating - Heater Mats
Diagnosis and Testing

Principles of Operation Published: 12-Jun-2013

Heated seats incorporate heater elements in the cushion and the backrest of the seat. Each cushion heater element has a
thermal sensor, which supplies a feedback temperature signal to the related seat heater module. The backrest heater elements
do not have a thermal sensor, and are regulated at the same temperature as the cushion heater elements.

For a detailed description of the seat heater mat, refer to the relevant Description and Operation section in the workshop
manual. REFER to: (501-10)

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTC's) and refer to the 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 (section B1.2), 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).


When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.

workshop manual. REFER to: (501-10 Seating)

Seats (Description and Operation), Seats (Description and Operation), Seats (Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle
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


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals


The DTC index containing an actions list is for guidance only any reference to “check and install new blower unit” should
only be carried out following failure confirmation using the pin out diagnostics and/or the over temperature and fluid/air leak
diagnostics contained below. The recording of a DTC does NOT signify a permanently failed unit


The climate system functions in a manner that means any detected error state either intermittent or permanent will shut
down the complete seat climate system until the next ignition cycle, this does not mean that both climate units within the one
seat have failed. This shut down is design intent to protect the system to ensure that the fault detected does not damage the
units, it is possible that both units are functioning correctly and that the fault lies elsewhere within the system. The following
process can be carried out without removing either the seats or the climate units from the vehicle and should correctly identify
any failed units, this should ensure that only failed units are changed under warranty. Any units exhibiting the correct reading
as per process below, should NOT be changed under warranty. If all units have a correct reading then re-confirm customer
symptom, if customer symptom is still present then carry out further system checks
1. Verify the customer concern

2. Visually inspect for obvious signs of mechanical or electrical damage

4. If the cause is not visually evident, carry out normal dealer warranty process, perform on-demand self test, check for
DTCs and refer to the relevant DTC index

5. Allow 30 mins since the last seat/cooled operation prior to carrying out pin testing detailed below in the section
"Connector and Pin Information"

6. Locate climate seat module, (refer to Electrical Information - Electrical Reference Library, contained in TOPIx) for
guidance on how to gain access to the connector(s)
7. Locate and disconnect relevant connector prior to pin test

8. Using ohm-meter to probe each heat/cooled unit pins (at rear of connector), reading should achieve no greater than 10
ohms after 1 minute (initial fluctuations in readings may occur using ohm-meter, post 1 minute readings will have
stabilized)

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

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
