TECHNICAL
Subject:
Intermittently Inoperative Heated Seats (Reprogram HVSM/MSM (Seat Module))
Models:
2007 GMC Acadia
2007 Saturn OUTLOOK
with Heated Front Seats (RPO KA1)
Condition
Some customers may comment that the heated front seats are intermittently inoperative when:
The customer starts the vehicle.
The heated seat is then switched "ON" to pre-heat the seat without an occupant in the seat.
The driver or passenger occupies the seat that has been pre-heated.
Under this set of circumstances, the heated seat may switch itself "OFF" when the seat becomes occupied and may not respond to the heated seat switch
until the next ignition cycle.
Cause
Due to an anomaly in the programming, an interaction between the seat module and the occupant sensor in the seat may exist, causing the seat heater to
switch off.
Correction
An updated calibration has been released to address this condition. Reprogram the seat module using SPS. This new service calibration is available on
TIS2WEB.
