- Adjustable Foot Pedal Position Sensor Circuit Short to Ground or Open
Diagnostic Fault Information
Circuit/System Description
The memory seat module (MSM) monitors the location of the adjustable pedals using the adjustable pedals position sensor. The adjustable pedals
position sensor is supplied with 5-volt reference and ground circuits from the MSM. The position sensor signal circuit is referenced from ground
within the MSM. The signal voltage monitored by the MSM ranges from 0.45-4.55 volts.
Conditions for Running the DTC
System voltage to the MSM must be 9-16 volts.
Conditions for Setting the DTC
The position sensor input to the MSM is not within the 0.45-4.55 volt range.
Action Taken When the DTC Sets
Memory recall functions will be suspended.
