Seat Travel Guard Bands
1999 Chrysler 300M V6-3.5L VIN GSECTION Seat Travel Guard Bands
The memory heated seat/mirror module (MHSMM) provides guard bands which prevent the seat track from hitting the hard limits of the given seat axis during manual power seat operation. The guard band values for each hard limit are stored in EEPROM. The guard band can be bypassed by running the seat to the end of its travel and then releasing the switch and pressing it again. The seat will move a short distance further. Once the seat is past the guard band it can be stored in memory, but if recall is initiated the seat will move to the guard bands and no further.
