Crunching The Numbers: U2109 Fixing Cost & Complexity
The fault code U2109 is related to a communication issue between the Engine Control Module (ECM) and the Electronic Brake Control Module (EBCM).
The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.
Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.
U2109 Fault Code: Understanding The Communication Error
The U2109 code is a Loss of Communication Diagnostic Trouble Code (DTC). It indicates that there is a malfunction in the Controller Area Network (CAN) serial data circuits. This malfunction causes a loss of communication with the Powertrain Multiple Control System.
The U2109 code is set by other modules that depend on information from the failed module. If any of the CAN circuits are shorted to battery voltage, ground, or between them, no communication is possible on the CAN serial data bus, and a Diagnostic Trouble Code will set.
