Selective Control Valve I-VI (SV1-6) 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.

Diagnostic Trouble Codes for all SCV controllers are similar. In the left column of the following table an “x” replaces the individual SV controller number. (Example: a DTC SV1 000158.04 has the same solution as a DTC SV6 000158.04.)
