B0087 Code: Meaning, Causes, and Symptoms | OBD2 Codes
B0087 – Left Rear Side Impact Sensor
B0087 Possible Symptoms
Air Bag Warning Light ON
B0087 Possible Causes
Faulty Left Rear Side Impact Sensor,Left Rear Side Impact Sensor harness is open or shorted,Left Rear Side Impact Sensor circuit poor electrical connection,Faulty Sensing and Diagnostic Module (SDM)
The impact sensors are equipped on vehicles to supplement the Supplemental Inflatable Restraint (SIR) system performance. The impact sensors are electronic and are not part of the deployment loops, but instead provide inputs to the Sensing and Diagnostic Module (SDM). The impact sensors can assist in determining the severity of some frontal and side collisions. The SDM uses the input from the impact sensors to assist in determining the severity of a collision further supporting air bag deployment. If the SDM determines a deployment is warranted, the SDM will cause current to flow through the deployment loops deploying the air bags.
