U1466 RAM Code - Implausible Driver Shift Request Signal Received On DPT CAN
Quick Answer
The purpose of the diagnostic is to monitor the Controller Area Network (CAN) BUS, the transmitted messages on the CAN BUS and the validity of the CAN signals. Common causes include Faulty Electronic Shift Module (ESM), Electronic Shift Module (ESM) harness is open or shorted, Electronic Shift Module (ESM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
