BMWR1200c Posted September 27 Report Share Posted September 27 (edited) 2020 Edge SEL. Based on these FCIM results in FORScan is there any reason to believe my heated side mirrors and rear defroster are not functional and need to be enabled? Just got the car in July and still too warm out to test. I've seen FORScan say things are not enabled when they are, and vice-versa. Thanks!

Haz Posted September 28 Report Share Posted September 28 From the 2020 Edge Workshop Manual... System Operation - Exterior, Heated Mirrors The rear window defrost system controls the operation of the heated exterior mirror glass and, if equipped, the heated spotter mirror glass. The heated exterior mirror glass and the heated spotter mirror glass only operates when the rear window defrost system is active. The heated mirrors are heated for a period of 10 minutes when the engine is running and the rear window defrost system is activated. To verify if the rear window defrost system is enabled... A2 CHECK THE REAR WINDOW DEFROST GRID VOLTAGE Ignition OFF. Disconnect: Heated Rear Window Element C402A. Start the engine. Activate the rear window defrost switch. Measure: Positive Lead Measurement / Action Negative Lead C402A Pin 1 Ground Is the voltage greater than 11 volts?

Wubster100 Posted September 29 Report Share Posted September 29 The options that you see in FORScan are not always 100% reliable and correct. There may be differences due to vehicle model, firmware revision, region, etc. Quote Link to comment Share on other sites More sharing options...
