Engine Interface Control Unit (EIC) Diagnostic Trouble Codes

Although the diagnostic codes listed below are not a complete list of the diagnostic trouble codes, they do reflect codes which may be observed while operating the tractor and have corrective action that the operator can correct. Many codes which appear may be corrected simply by cycling key switch or by following the solution on the CommandCenter™ page, then cycling tractor power.

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