2010 Dodge Avenger with Codes C2100, C2202, U14-0E, C2101: No Engine Light, ABS Issues & EVAP Concerns

Hi everyone, new to the forum and I expect to be active as I'm taking more hands-on involvement with my vehicle. We recently purchased a used 2010 Dodge Avenger 3.5L R/T from a dealership. Within one week of ownership, it started throwing multiple diagnostic codes — though no engine light is illuminated. A scan reveals the following codes: C2100, C2202, U140E, and C2101. The car has been rebuilt and passed provincial inspection with a warranty stating that no diagnostic codes should appear for three months. The dealer claims this covers the issue, but I want to verify whether the repairs were properly completed. After researching these codes, I’ve identified common root causes: - **C2100 – Abnormal Battery Voltage (Low)**: Possible battery failure, loose terminals, charging system malfunction, damaged wiring harnesses, or ABS-ECU issues. - **C2202 – Original VIN Mismatch**: The VIN stored in the Anti-Lock Brake Module (ABM) does not match the actual vehicle’s VIN. This is a known issue when brake modules are replaced without proper reprogramming. - **U140E – Implausible Vehicle Data Received**: Causes ABS and traction control lights to illuminate, disables cruise control, and prevents interaction with traction control systems. The Powertrain Control Module (PCM) configuration must be updated; the ABS module receives inconsistent data from the PCM, leading to this fault. - **C2101 – Battery Voltage High**: Could stem from a faulty ECM, vehicle battery, charging system, or defective Anti-Lock Brake System (ABS) module. My initial theory is that an ABS module was replaced during the rebuild but not properly reprogrammed with the correct VIN. Is this a plausible explanation? If so, what specific checks and actions should be taken? Additionally, I’ve noticed the gas cap warning light comes on intermittently. While I suspect it’s unrelated, I also observed that the fuel pump frequently stops during refueling — which may point to an EVAP system issue. Any insights or troubleshooting steps would be greatly appreciated. Thanks in advance for your help!
