- Summary
- DESCRIPTION Some customers may complain that the seat warmer does not operate when turning the ignition on while the seat is warm but when turning the ignition off then on again, the seat warmer begins to operate appropriately. DTCs “B1030:13” and/or “B1032:13” are stored. This is caused by the seat warmers fail-safe mode which prevents it from working during the initial drive cycle. To correct this issue, the seat warmer has been modified to optimize the temperature control.
