associated to a set resistance value and when pressed a specific voltage drop occurs across the resistor unique to the switch. The BCM identifies the



switch selection and activates the feature.



Conditions for Running the DTC



* The system voltage is between 9-16 V.



* The ignition is ON.



Conditions for Setting the DTC



* The BCM detects a short to voltage on the signal circuit.



* The above condition is present for greater than 30 s.
