U1449 RAM Code - Implausible ERS Message Recieved Transmission Control Module
Quick Answer
The U1449 diagnostic trouble code (DTC) refers to an "Implausible ERS Message Received Transmission Control Module." This code indicates that the vehicle's Transmission Control Module (TCM) has detected an error in the communication with the Electronic Range Select (ERS) system. Common causes include Faulty ERS sensor: A malfunctioning sensor in the ERS system can send incorrect data to the TCM, Wiring issues: Damaged or corroded wiring connections between the TCM and ERS system can cause communication errors, TCM software glitch: An issue with the TCM software can lead to miscommunication with the ERS system. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U1449 RAM Description
The U1449 diagnostic trouble code (DTC) refers to an "Implausible ERS Message Received Transmission Control Module." This code indicates that the vehicle's Transmission Control Module (TCM) has detected an error in the communication with the Electronic Range Select (ERS) system. The ERS allows the driver to manually select the gear range in an automatic transmission vehicle, providing more control over shifting.
Common Causes of U1449 RAM
- Faulty ERS sensor: A malfunctioning sensor in the ERS system can send incorrect data to the TCM.
- Wiring issues: Damaged or corroded wiring connections between the TCM and ERS system can cause communication errors.
- TCM software glitch: An issue with the TCM software can lead to miscommunication with the ERS system.
- ERS system malfunction: Internal faults within the ERS system can cause inaccurate data transmission to the TCM.
Symptoms of U1449 RAM
- Erratic shifting: The vehicle may experience rough or delayed shifting between gears.
- Reduced fuel efficiency: The engine may require more fuel to operate efficiently due to transmission issues.
- Transmission slipping: The vehicle may slip out of gear unexpectedly, causing a loss of power.
- Illuminated warning light: The Check Engine Light or Transmission Warning Light may come on to indicate a problem with the transmission system.
How to Fix U1449 RAM
- Diagnose the issue: Use a diagnostic scanner to retrieve the specific trouble code and perform further testing to pinpoint the exact cause of the communication error.
- Inspect wiring connections: Check the wiring harness between the TCM and ERS system for any damage or corrosion. Repair or replace any faulty connections.
- Test ERS sensors: Verify the operation of the sensors in the ERS system to ensure they are sending accurate data to the TCM.
- Update TCM software: If a software glitch is suspected, update the TCM software to the latest version to resolve any communication errors.
- Replace ERS system components: If internal faults are found in the ERS system, replace the faulty components to restore proper communication with the TCM.
Cost to Fix U1449 RAM
The typical repair costs for resolving the U1449 code can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of diagnosing and repairing this issue can range from $200 to $500, including parts and labor. However, it's essential to note that the actual cost can be higher or lower based on factors such as the vehicle make and model, the location of the repair shop, and the technician's labor rates. It is advisable to obtain a detailed estimate from a reputable auto repair shop to get an accurate idea of the total repair costs.
