Circuit/System Description
The adjustable pedals forward and rearward switches are inputs to the memory seat module. The memory seat module supplies the switch assembly with a battery positive reference voltage. When the switch is operated to the forward or rearward direction, battery positive voltage is applied to the forward or rearward switch signal inputs.
Conditions for Running the DTC
System voltage to the memory seat module must be 9-16 volts.
Conditions for Setting the DTC
The forward and rearward switch signal circuits are active at the same time.
Action Taken When the DTC Sets
