What Does B0097 Mean?
This code indicates the Restraint Control Module (RCM) has detected a malfunction or subfault with the second side impact sensor located on the right side of the vehicle. This sensor is part of the Supplemental Restraint System (SRS/airbag system) and monitors lateral impact forces to determine when to deploy side airbags or curtains. The subfault designation suggests an internal sensor issue, circuit problem, or communication fault rather than a complete sensor failure.
Safety Warning
This is a safety-critical fault that may prevent side airbags from deploying properly in a collision, leaving occupants unprotected. The vehicle should not be driven until repaired, and the airbag warning light will remain illuminated to alert the driver of the system malfunction.
Common Causes
45%
Faulty right side impact sensor 2 internal failure or calibration drift
30%
Damaged or corroded wiring harness or connector at sensor location
15%
Water intrusion or corrosion in sensor housing or connector
10%
Restraint Control Module software issue or internal fault
Diagnostic Steps
1
Step 1: Perform visual inspection of right side impact sensor 2 location (typically in right B-pillar, door, or rocker panel area) for physical damage, water intrusion, connector corrosion, or loose connections
2
Step 2: Using a digital multimeter, check sensor connector pins for proper voltage supply (typically 5V reference) and ground continuity when sensor is disconnected, comparing readings to manufacturer specifications
3
Step 3: Measure resistance across sensor terminals with sensor disconnected (typically 1-3k ohms depending on manufacturer) and compare to specifications to verify sensor integrity
4
Step 4: Inspect wiring harness from sensor to RCM for chafing, pinching, or damage, paying special attention to areas where harness passes through body panels or near door hinges
5
Step 5: Clear codes and perform RCM relearn/calibration procedure if available, then road test and monitor for code recurrence
6
Step 6: If all tests pass but code persists, replace right side impact sensor 2 and verify proper installation torque and orientation, then clear codes and verify repair

The most common cause of B0097 (Right Side Restraints Sensor 2 (Subfault)) is: Faulty right side impact sensor 2 internal failure or calibration drift
Typical repair costs for B0097 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is a safety-critical fault that may prevent side airbags from deploying properly in a collision, leaving occupants unprotected. The vehicle should not be driven until repaired, and the airbag warning light will remain illuminated to alert the driver of the system malfunction.
