GO to Pinpoint Test G1014305t24.

G1014305t24 : Driver Or Front Passenger Seat Backrest
Climate Assembly - Noise

1. There is a known issue which effects a limited number of vehicles where under acceleration
of the vehicle the occupant of seat can deform the suspension mat (snake wire) which then
presses on the casing of the seat backrest climate assembly, this causes the casing to distort
and the noise issue to occur. If contact has occurred there will be a witness mark on the
casing. Carry out visual inspection of the seat backrest climate assembly that has been
identified as noisy by the customer.

•

Is there a witness mark on the casing?

-> Yes
Contact the local in market support for further information.

-> No
GO to Pinpoint Test G1014305t25.

G1014305t25 : Driver Or Front Passenger Seat Climate
Assembly - Noise 2

1. Operate the heat and cool function of the seat. Listen for a 'WAH WAH' noise (the fan
speeds up and slows down repeatedly).

•

Does the fan speeds up and slow down repeatedly?

-> Yes
Confirm the latest Strategy and Calibration software is installed, using the manufacturer
approved diagnostic system carry out the new Climate Controlled Seat Module application
and update the Climate Controlled Seat Module software if required. If the noise is still
evident after software update follow link below. GO to Pinpoint Test G1014305t26.


-> No
GO to Pinpoint Test G1014305t26.

Climate Assembly - Noise level Comparison

1. Compare the noise level of the suspect climate seat assembly to another climate seat
assembly.

•

Is the noise level equal between the two seats?

-> Yes
The noise level is standard and comparable to the design intent.

-> No
Suspect an internal fault with the Seat Climate Assembly. Replace as required, refer to the
Warranty Policy and Procedures manual (section B1.2). Prior to installing a new component.
