Selective Control Valve Units (SV) 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 take. Many codes which appear 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 cycling power to the tractor or if there are any questions, contact your John Deere™ dealer.

All though specific SCV number is listed in the table, the following trouble codes may be true of any SCV on the tractor. If an SV code is displayed, make sure that you note exactly which SCV it is and take appropriate action for that specific SCV as described in the solution column for the trouble code.
