Defrost Switch Request Input Circuit Performance
Description
The HVAC A C Heater Control contains various switches and knobs that are used to change the systems operation. Many of the switches are momentary switches which are normally open or in the Off position and the status changes when the switch button or knob is pushed or turned. An active DTC indicates that the switch is stuck in an On position. A stored DTC indicates that the switch was stuck in a On position for more than four minutes but has since returned to its normal state of Off.
