What Does U2017 Mean?
The driver side crash sensor (impact sensor) is not communicating properly with the airbag control module. This affects the airbag system's ability to detect and respond to collisions on the driver side.
Safety Warning
Critical safety concern. Driver side airbags may not deploy properly in a collision. Airbag warning light will be illuminated. Repair immediately for occupant safety.
Common Causes
35%
Failed driver side crash sensor from impact damage or internal failure
30%
Damaged wiring or connector to driver side crash sensor from previous collision
20%
Corrosion in crash sensor connector due to water intrusion
15%
Loss of power or ground to the crash sensor circuit
Diagnostic Steps
1
Step 1: Locate driver side crash sensor (typically in driver door, B-pillar, or front fender area)
2
Step 2: Inspect sensor mounting area for signs of previous impact damage or sensor displacement
3
Step 3: Check sensor connector for corrosion, water intrusion, or damaged terminals
4
Step 4: Verify power and ground at crash sensor connector per manufacturer specifications
5
Step 5: Check communication circuit continuity between sensor and airbag control module
6
Step 6: Clear codes and test; if sensor has experienced actual impact, replacement is required
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The driver side crash sensor (impact sensor) is not communicating properly with the airbag control module. This affects the airbag system's ability to detect and respond to collisions on the driver side.
The most common cause of U2017 (Driver Side Crash Sensor Communication Fault (Non SCP)) is: Failed driver side crash sensor from impact damage or internal failure
Typical repair costs for U2017 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Critical safety concern. Driver side airbags may not deploy properly in a collision. Airbag warning light will be illuminated. Repair immediately for occupant safety.
