: Use a JLR-approved diagnostic tool to clear the DTCs. If the code does not return immediately after a test drive, it was likely a transient voltage issue.
: If the code persists, refer to electrical circuit diagrams to test the crank signal input circuit for high resistance or a physical short to the chassis.
The Land Rover fault code specifically indicates an "Engine Speed Input - Circuit Short to Ground" within the Audio Amplifier Module (AAM) . While seeing an engine-related code in an audio module might seem alarming, this DTC is generally regarded as a "ghost code" that does not typically affect the vehicle's drivability or even the primary functions of the infotainment system.
