Code B224E RAM Description

The B224E RAM diagnostic trouble code (DTC) indicates an internal malfunction within the Power Liftgate Module (PLM) of a vehicle. The PLM is responsible for controlling the operation of the power liftgate, which includes functions such as opening, closing, and locking the liftgate, as well as managing any associated sensors and switches. When this code is triggered, it suggests that the module has detected an internal fault, which could stem from various issues such as software glitches, hardware failures, or electrical problems.

  3. Warning lights or messages on the dashboard indicating a liftgate issue.
  4. Unusual noises coming from the liftgate area when attempting to operate it.
  5. The liftgate may not respond to remote or manual controls.

How to Fix B224E RAM

  1. Diagnostic Scan: Begin by using an OBD-II scanner to confirm the B224E code and check for any additional trouble codes that may provide further insight into the issue.
  2. Visual Inspection: Inspect the wiring harness and connectors associated with the PLM for signs of damage, corrosion, or loose connections.
  3. Module Testing: If the wiring appears intact, test the PLM for proper function using a multimeter or specialized diagnostic tool to assess its operational status.
  4. Software Update: If the module is functioning but still throwing the code, check for any available software updates from the manufacturer that may resolve known issues.
  5. Module Replacement: If the module is determined to be faulty and cannot be repaired, replace it with a new or refurbished unit, ensuring that it is programmed correctly to the vehicle.

Cost to Fix B224E RAM

The typical repair costs for addressing a B224E RAM code can range from $200 to $800, depending on whether the issue is resolved through simple repairs or requires a full module replacement. This estimate includes parts and labor, with the cost of a new Power Liftgate Module often falling between $150 and $500. Labor costs can vary significantly based on location, vehicle make and model, and engine type.
