What Does the U1460 RAM Code Mean?

This diagnostic checks the availability and rationality of the Engine Idle Speed signal which is sent by the Engine Control Module (ECM) via a Controller Area Network (CAN) message. The diagnostic determines the availability by checking the received value is not equal to the Signal Not Available (SNA) default value. Then the diagnostic checks the rationality by confirming the signal value is within the range defined by a lower and upper threshold. When the CAN signal value is below a calibratable lower threshold or it exceeds a calibratable upper threshold or the signal is not available, the Powertrain Control Module (PCM) sends a Signal Not Available (SNA) default value to the PCM. When the PCM reads one of these conditions then the Diagnostic Trouble Code (DTC) U1460 is set.
