Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Roll-Over Sensor (Only XC60)
The Roll-Over Protection System (ROPS) consists of a roll-over sensor, of the type gyro sensor, which senses the vehicle's angle. The roll-over sensor is used to give Supplemental Restraint System Module (SRS) early information in case of a roll-over.
If the vehicle's sideways angle changes fast enough, then Supplemental Restraint System Module (SRS) will start a calculation how high the rotation energy is. If the rotation energy is high enough, the control module will activate the roll-over protection.
The roll-over protection activates all seatbelt tensioners and inflatable curtains in the vehicle.
In case of incorrect signal from the roll-over sensor, the control module generates a diagnostic trouble code.
The roll-over sensor is installed on the circuit board on Supplemental Restraint System Module (SRS).
