Automatic Temperature Control Unit (ATC) Diagnostic Trouble Codes

Although no diagnostic codes are listed below, normally only codes which are observed and can be corrected by the operator are listed. During normal tractor operation some trouble codes may appear which may be corrected simply by cycling key switch or by following the solution on the CommandCenter™ page, then cycling key switch.

If corrective action cannot be taken after rcycling power to the tractor or if there are any questions, contact your John Deere™ dealer.

IMPORTANT: Check the cleanliness of the condenser at the front of the tractor and make sure the cab recirculation air filter is not plugged for all ATC diagnostic trouble codes. If the codes return, contact your John Deere dealer as soon as possible.
