John Deere SV7 fault codes / John Deere SV7 diagnostic trouble codes
NOTE:This page only indicates the meaning of the fault codes. For complete troubleshooting information, see the technical manuals.
SCV control lever communicates its position to the ACU. This information is sent to the SCC through tractor CAN bus. It is then converted and sent to appropriate SV control unit through SCC/SV CAN Bus. SCV control lever will provide a means of controlling SVs in a number of different ways, depending on operation mode or position of
lever.
When lever is moved to extend or retract detent position and released to center, the SV will be commanded to fully extend or fully retract position. The detent action will take place after the lever has been released to the neutral region. When the lever is released from detent, it must return to the neutral region within 0.8 seconds or the detent action will not be executed. This allows a detent action to be canceled if the detent was inadvertently entered while attempting to move the lever to the maximum associated midrange position. There will be no time limit on how long the lever can be held in the detent position. However, while held in this position, the SV response will be as if the lever was at the maximum associated midrange position.
John Deere SV7 fault codes / John Deere SV7 diagnostic trouble codes
SV7 000158.03 (SV7 158.03)— SV VII Switched Supply Voltage High
Code Caused By: Switched supply voltage to Selective Control Valve Unit VII (SV VII) above 16.0 V.
NOTE: Associated Codes: This code and other 000158.XX codes may be present in other control units. Since Vehicle Load Center (VLC) control unit wake-up circuit is voltage source, perform VLC code diagnostics first.
SV7 000158.04 (SV7 158.04)— SV VII Switched Supply Voltage Low
Code Caused By: Switched supply voltage to Selective Control Valve Unit VII (SV VII) below 9.0 V.
NOTE: Associated Codes: This code and other 000158.XX codes may be present in other control units. Since Vehicle Load Center (VLC) control unit wake-up circuit is voltage source, perform VLC code diagnostics first.
SV7 002034.09 (SV7 2034.09)— SCC Message Missing
Code Caused By: Selective Control Valve Unit VII (SV VII) not receiving required messages from the SCC.
SV7 004084.07 (SV7 4084.07)— SV VII Not in Float Position
Code Caused By: Selective Control Valve VII (SV VII) not going into FLOAT position.
SV7 004084.16 (SV7 4084.16)— SV VII Overshot Commanded Position
Code Caused By: Selective Control Valve VII (SV VII) spool is over-shooting its desired position.
SV7 004084.18 (SV7 4084.18)— SV VII Failed to Reach Commanded Position
Code Caused By: Selective Control Valve VII (SV VII) spool is under-shooting its desired position.
NOTE: If multiple valves are generating a 004084.18 code, refer to etermining Total Flow Demand in Operator’s Manual to correctly set flow.
SV7 004085.07 (SV7 4085.07)— SV VI Not in Neutral Position
Code Caused By: Selective Control Valve VI (SV VI) is not in NEUTRAL position. Code can also be caused by moving control lever with key on, engine off.
SV7 004085.12 (SV7 4085.12)— SV7 Control Unit Fault
Code Caused By: Selective Control Valve Unit VII (SV VII) software failed to execute in allotted time.
