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)

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

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.
Visual inspection
Mechanical Electrical Seat heater switches condition and installation Fuses
Harnesses and connectors
Seat heater module
Seat heater switches
Seat heater mat
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.

manual, or determine if any prior approval programme is in operation, prior to the installation of a new module/component. Clear any stored DTC's and retest A5: POWER CONSUMPTION
NOTE: The seat heater power supply cycles on and off dependant on the seat and cabin temperature and may only
switch on for 5 seconds in 30 seconds 1 Reconnect the connector 2 Operate the vehicle air conditioning on full for 10 minutes to reduce the in vehicle ambient temperature 3 Refer to the electrical circuit diagrams and check the seat heater mat ( heater circuit ) using a current clamp 4 Operate the seat heater on full power 5 Use the chart above to calculate typical value (V/R=I) (Volts divided by Resistance equals Current in Amps) 6 Examples (12 volts / 0.5 ohms =24 amps) (12 volts / 1 ohms = 12 amps) (12 volts / 2 ohms = 6 amps) Does the seat heater mat consume the correct level of current?
Yes
Clear any stored DTC's and retest. If operation correct, no further action required
No
GO to A6. A6: RESISTANCE CHECK NOTES:


Ensure the multimeter used is calibrated and a resistance reading of 0 ohms is shown when the test leads are connected
together, alternately subtract any resistance shown from the result
The seat heater mat circuits should be checked at the seat heater module connector
Refer to the electrical circuit diagrams and to confirm the total resistance of the circuit the cushion and backrest are
connected in series 1 Refer to the electrical circuit diagrams and the seat heater mat application chart (see above) to identify the terminals 2 Disconnect the connector 3 Using a multimeter, carry out a resistance check of the seat heater mat heater circuit and the NTC resistor circuit. Record the results 4 Compare the results to the chart (see above) Are the results within specification at the given ambient temperature? (tolerance +/- 0.5 Ohms)
Yes
Reconnect the connector. Clear any stored DTC's and retest. If customer concern or DTC's return refer to
electrical circuit diagrams and investigate the power and ground supply circuits
No
Replace the seat heater mat as required. 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. Clear any stored DTC's and retest www.JagDocs.com

Seating - Seats Vehicles With: Climate Controlled Seats
Diagnosis and Testing

Principle of Operation Published: 16-Apr-2014

For a detailed description of the seating systems and operation, refer to the relevant description and operation section of the
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

Visual Inspection
Mechanical Electrical
Seat heater switch condition and installation
Battery condition and state of charge
Fuses
Harnesses and connectors
Seat heater switch(es)
Seat heater elements
Seat module(s)
Ignition switch
Battery junction box
Central junction box
LIN circuit
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, 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"
