This error code highlights a conflict between the detent switch and the actual position of the SCV VIII (Selective Control Valve VIII) control lever. The inconsistency occurs when the detent switch, which is designed to detect the lever’s position, sends signals that do not correspond with the lever’s physical location. This misalignment can disrupt the…

This error code, AIC 521133.31, is generated when a fault with the CommandQuad™ transmission’s range switch B causes it, and potentially other switches, to be erroneously read as being pressed simultaneously. This simultaneous activation leads to conflicting signals being sent to the transmission system, which can result in incorrect gear selections and potential operational hazards.

John Deere error AIC codes
This error code indicates a malfunction with the CommandQuad™ transmission system’s range switch B, specifically that the switch may be stuck in the pressed position. This mechanical or electrical fault prevents the switch from returning to its neutral, unpressed state, leading to erroneous signals being sent to the transmission system.
