Front Riser Sensor Out of Range Low

NAME OF CODE
Front Riser Sensor Out of Range Low

WHEN MONITORED
Ignition on.

SET CONDITION
Immediately set.

THEORY OF OPERATION
The seat motors have potentiometers/sensors attached to them. When the seat moves a potentiometer value changes. The potentiometers are designed to operate within a window of values. Any values outside of the normal will cause a code to be set. Therefore, when the seat sensor feed back to the MHSMM is less than the seat sensor out of range low value stored in EEPROM, a code will be set.

PROBABLE CAUSE
- Seat motor failure (value)
- Front riser position signal ckt shorted to ground
- MHSMM failure
