That's where the factory service manuals come in handy. Here's what the codes mean:


DTC Description
DTC 10/110 Ambient Temperature Sensor CKT Open or Shorted
DTC 13/113 In-Vehicle Temperature Sensor CKT Open or Shorted
DTC 15/115 LH Solar Sensor Circuit Open or Shorted
DTC 35/135 E & C Data Line Failure With Heater and A/C Control Assembly
DTC 38/138 Serial Data Line Failure With PCM
DTC 40/140 Driver Air Mix Motor CKT Open or Shorted, or Not Calibrated
DTC 48/148 Long Term Freon Loss
DTC 52/152 Keep Alive Memory Lost: Sets With Battery Disconnected
DTC 66/166 Low Freon

NOTE: A number 1 prefix on any diagnostic trouble code indicates a history DTC.

This indicates no freon (more than likely a leak somewhere in the system), and a faulty calibration of an air mixer. The 52 will set if the battery is disconnected and is no big deal. You will need to find and correct the reason for no freon before you can procede.
