U1508 Meaning

The messages sent on the Controller Area Network (CAN) bus are distinguished by an Identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID. The Diagnostic Trouble Code (DTC) will set when the TCM detects an incorrect CAN ID from the Electronic Shift Module (ESM).
