Do This | Don't Do This |
|---|---|
Reprogram the HVSM module. | Do not replace any physical component of the heated seat system. |
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 heated seat module and the occupant sensor in the seat may exist causing the seat heater to switch off.
