OBD-II code B0096 indicates a fault in the right side restraints sensor 1 circuit. This sensor is part of the supplemental restraint system (airbag system) and is typically located on the right side of the vehicle to detect side impacts. The code sets when the restraint control module detects an abnormal voltage, resistance, or communication error from this sensor.
The sensor itself has failed internally due to age, impact damage, or manufacturing defect. This is the most common cause of the code.
Wires leading to the sensor may be chafed, broken, or pinched, often from collision damage, improper repairs, or routing near moving parts.
Corrosion, loose terminals, or a partially disconnected connector can cause intermittent or high-resistance faults.
Wiring insulation damage can cause the signal wire to contact ground or a power source, leading to out-of-range readings.
The module that monitors the sensor may have an internal fault, though this is less common than sensor or wiring issues.
The vehicle may be drivable, but the airbag system may not deploy properly in a side impact, increasing the risk of injury. It is strongly recommended to repair the fault promptly.
Working on airbag systems carries a risk of accidental deployment and injury. Disconnect the battery and wait the specified time before handling components. If you are not experienced with SRS repairs, seek professional assistance.
In most cases, no. The sensor or its wiring is the cause. The control module should only be replaced after thorough diagnosis confirms it is faulty, which is rare.
No. The powertrain control module (PCM) does not control the restraint system. This code is set by the restraint control module (RCM), a separate computer. Replacing the PCM will not fix a B0096 code.
