The RAM Code U1418 is a code that is used to identify a common problem with the Powertrain Control Module (PCM) in a vehicle. It is triggered when the PCM receives an implausible proper wheel distance signal and is accompanied by a wheel speed and wheel distance CAN C bus message from the Anti-lock Brake (ABS) module. This code is typically an indication of a WHEEL SPEED SENSOR WIRING ISSUE, a faulty WHEEL SPEED SENSOR, a faulty ANTI-LOCK BRAKE SYSTEM (ABS) MODULE, or a defective BODY CONTROL MODULE (BCM).

Solution:
- CHECK WHEEL SPEED SENSOR WIRING
- REPLACE THE WHEEL SPEED SENSOR
- REPLACE THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE
- REPLACE THE BODY CONTROL MODULE (BCM)
Troubleshooting RAM Code U1418
| Cause | Solution |
|---|---|
| WHEEL SPEED SENSOR WIRING ISSUE | CHECK WHEEL SPEED SENSOR WIRING |
| WHEEL SPEED SENSOR | REPLACE THE WHEEL SPEED SENSOR |
| ANTI-LOCK BRAKE SYSTEM (ABS) MODULE | REPLACE THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE |
| BODY CONTROL MODULE (BCM) | REPLACE THE BODY CONTROL MODULE (BCM) |
The RAM Code U1418 is a common issue encountered when diagnosing a vehicle. It is a code that is used to identify a problem with the Powertrain Control Module (PCM) when it receives an implausible proper wheel distance signal from the Anti-lock Brake (ABS) module. If you are encountering this code, it is likely due to a wheel speed sensor wiring issue, a faulty wheel speed sensor, a faulty ABS module, or a faulty BCM. To troubleshoot this issue, it is essential to check the wheel speed sensor wiring, replace the wheel speed sensor, replace the ABS module, and replace the BCM. All of these solutions can help to resolve the RAM Code U1418 issue.
Conclusion
When diagnosing a vehicle, the RAM Code U1418 is a common issue that may be encountered. This code is typically an indication of a WHEEL SPEED SENSOR WIRING ISSUE, a faulty WHEEL SPEED SENSOR, a faulty ANTI-LOCK BRAKE SYSTEM (ABS) MODULE, or a defective BODY CONTROL MODULE (BCM). To fix this issue, it is essential to check the WHEEL SPEED SENSOR WIRING, REPLACE THE WHEEL SPEED SENSOR, REPLACE THE ANTI-LOCK BRAKE SYSTEM (ABS) MODULE, and REPLACE THE BODY CONTROL MODULE (BCM). By following these steps, the RAM Code U1418 can be resolved.
