A/C solar sensor circuit code 21
Hey guy`s I need a little advice here,just for the heck of it I did a systems check on my A/C.Well low and behold a code 21 pops up,solar sensor circuit.I tried disconnecting the battery for around a minute,and it does not get rid of it.Does any one know what this sensor does?? the air seems to be working very well,and I really dont understand why disconnecting the battery doesnt get rid of the code.
*** since I did this in my garage under dim lighting conditions,This is probably why i got this code.I`ll try again tomorrow out side and see what happens.Does this sensor compensate for the sun shining in the car or something??
