U1412 Chrysler Code - Implausible Vehicle Speed Signal Received

Quick Answer

The purpose of the monitoring is to detect rationality failures of the input speed and output speed sensor signals, as well as the wheel speed and engine speed, Controller Area Network (CAN) signals. Common causes include Faulty Anti-Lock Brake System (ABS) Module, ABS Module harness is open or shorted, ABS Module 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.

Code U1412 Chrysler Description

The purpose of the monitoring is to detect rationality failures of the input speed and output speed sensor signals, as well as the wheel speed and engine speed, Controller Area Network (CAN) signals. There are three categories of rationalities which include: Multi-sensor comparisons of up to three signals (input, output, and wheel speed). Monitoring of the gradient of the input speed signal. Double failure monitoring to determine unique failure situations that could require unique limp-in functionality. The Diagnostic Trouble Code (DTC) sets when the failure is detected if the output speed gradient is less than a threshold for a calibrated amount of time.
