The automobile fault code U1449 indicates a problem with the Transmission Control Module (TCM) or Cabin Compartment Node (CCN).
The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty TCM, an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty CCN.
The repair importance is high as it affects the transmission system, and the repair difficulty is moderate.
To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be 1.0 hour. It is essential to interpret the fault code to identify the root cause of the problem and take appropriate action.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |

Crunching The Numbers: U1449 Repair Cost & Complexity
The automobile fault code U1449 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of fixing the U1449 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to diagnose and fix the issue.
Unlocking The Mystery Of U1449 Fault Code
The U1449 fault code is related to the Electronic Range Select (ERS) operation of the Transmission Control Module (TCM) in automobiles.
The ERS switch is connected to the Cabin Compartment Node (CCN), which sends a CAN bus message to the TCM.
If the TCM does not receive or receives an invalid ERS message, the U1449 Diagnostic Trouble Code (DTC) is set, indicating an Implausible ERS Message Received by the Transmission Control Module.
