Front Seats
Seat heater cable harness reroutingFunctional checks 1
Check the functionality by turning on the seat heater and checking whether the back and seat cushions are being heated.
If it is not functioning properly, proceed to step 2.
Checking the heating coil in the element
Connect an ohmmeter to the terminal pin for the heating elements in the connector block that connects to the car's cable harness.
If the meter reacts, then there is a connection through the coils and the elements are functioning electrically.
If the meter does not react, cool down the thermostat with cold atomizer in order to verify seat heater function.
If the Seat heater does not function, it should be noted on the Repair Order.
Preparations, mechanically adjusted seats 3
Fully raise the seat at the front edge. Fully lower the rear edge of the seat. Slide the seat as far back as possible.
Hint:
This operation is easier if the front-rear adjustment-mounting bracket is removed from the seat.
Disconnect the connector between the car cable harness and the seat heater under the seat.
Changing the location of the connector, mechanically adjusted seats 4
Disconnect the 6-pin connector (1) and the clip on the seat cable harness from the bracket on the seat. Install the 6-pin connector (1) on the underneath of the bracket, pointing towards the back of the car.
Preparations, power seats 5
Fully raise the seat at the front edge. Fully lower the rear of the seat. Slide the seat as far back as possible. Disconnect the connector (1) between the car cable harness and the seat heater under the seat.
Changing the location of the connector, power seats 6
Disconnect the 6-pin connector and the clip on the seat cable harness from the bracket on the seat. Install the connector (1) on the bracket under the green connector (2) for the control module.
Installing a new cable harness 7
Disconnect the grey and black 2-pin connector (1) for the heater pad.
Connect the new cable harness to the 2-pin grey and black connector (2) for the heater pad.
NOTE:
Only a power seat is shown.
Installing the electronic thermostat (TCU-T) 8
Install the clip from the kit in the rectangular hole on the inner most tab.
Screw the electronic thermostat into place on the clip.
Note!
Ensure that the existing cable is not trapped.
Manual seat: 9
Connecting the electronic thermostat (TCU-T) to the car cable harness
Connect the 6-pin connector (with 2 cables) from the new cable harness to the existing connector (1) on bottom of the bracket.
Install the new 6-pin connector (2) from the thermostatic relay to top of the bracket.
Manual seat: 10
Connection to the new 6-pin connector
Connect the car cable harness to the new 6-pin connector (2).
Power seat: 11
Connecting the electronic thermostat (TCU-T) to the car cable harness
Connect the 6-pin connector (with 2 cables) from the new cable harness to the existing connector (1).
Install the 6-pin connector (2) and mounting on the bracket for the connectors in the same place as the connector (2), which was moved.
Power seat: 12
Connecting to the new 6-pin connector
Connect the car cable harness to the new 6-pin connector (2).
Securing the loose connectors 13
Install the foam rubber around the 2-pin connectors. Secure the connectors through the bracket on the seat and around the cable harnesses. Use a tie strap. See the illustration.
Functional checks 14
Check the functionality by turning on the seat heater and checking whether the back and seat cushions are being heated.
If the heater does not function connect an ohmmeter to the terminal pin for the heating elements in the connector block that connects to the car's cable harness.
If the meter reacts, then there is a connection through the coils and the elements are functioning electrically.
If the meter does not react, cool down the thermostat with the cold atomizer in order to verify seat heater function.
If the heater does not function, it must be noted on the Repair order. Any further fault tracing or repairs are not included in this Recall.
Check that no cables are trapped and that they cannot be subjected to damage by rubbing, stretching, etc. or be the cause of rattling noise.
Perform the check with the seat in all end positions. Adjust the wirings as needed.
