Driver Side Crash Sensor Communication Failure
The U2017 code indicates a communication failure between the driver side crash sensor and the Restraint Control Module (RCM). The '(Non SCP)' suffix means the sensor does not use Ford's Standard Corporate Protocol but instead communicates via CAN or a dedicated bus. This fault prevents the RCM from receiving a valid signal from the driver side impact sensor, which can disable proper airbag deployment in a collision.
1. Commonly Affected Makes
2. Most Common Causes
- Internal failure of the driver side crash sensor
- Open or short circuit in the wiring between the sensor and RCM
- Corrosion or damage to the sensor connectors
- Electromagnetic interference or harness damage from a previous collision
- Excessive resistance in the sensor communication circuit
3. Symptoms You Will Notice
- Airbag warning light illuminated on the dashboard
- Supplemental Restraint System (SRS) fault message displayed
- Possible failure of airbag deployment in a crash
4. Step-by-Step Diagnosis
Scan the vehicle for all stored codes and note freeze frame data
Visually inspect the driver side crash sensor and its wiring for damage, corrosion, or loose connections
Test the sensor communication circuit for continuity, shorts, and resistance using a multimeter
Check for any technical service bulletins (TSBs) related to the sensor or RCM
If wiring is intact, test the sensor by substitution or using a diagnostic tool to verify communication
If sensor tests good, suspect a faulty RCM and perform further diagnosis or replacement
5. Frequently Asked Questions
Is it safe to drive?▼
No, it is not safe to drive. The airbag system may not deploy properly in a collision, increasing the risk of injury. Have the vehicle repaired immediately.
How much does it cost to fix?▼
Repair costs typically range from $200 to $600, depending on whether the sensor, wiring, or RCM needs replacement, plus labor.
