Front Impact Sensor

To be able to replace the inflatable restraint side impact sensor the first step involves disabling the SIR system. Make sure the sensor is not hit or shaken and it is properly secured before connecting to power to prevent deployment or harm. Put up the window for access then get rid of the door trim panel and enough of the water deflector to gain access to the sensor. Unscrew the bolts holding the sensor then remove the sensor from the door and sever the connector position assurance (CPA) from the side impact sensor connector. Remove the sensor, clean up the mounting surface, mount the new sensor near the door, and connect the side impact sensor connector. Mount the CPA onto the connector and bolt the sensor to the door applying a torque of 10 N.m (89 lb in). After that, re-install the water deflector and activate the SIR system.

Before you replace the Inflatable Restraint Side Impact Sensor you must disable the SIR system. Before connecting power ensure you have safely attached the inflatable restraint side impact sensor (SIS) and prevent SIR deployment and injury to personnel. Open the window for entry then pull out both the door trim panel and enough water deflector to see the side impact sensor . Start by loosening the sensor bolts then remove the sensor from the door while disconnecting the connector position assurance (CPA) from the side impact sensor connector. Bring the new inflatable restraint side impact sensor near the door while cleaning the mounting surface before attaching the sensor to its location using the side impact sensor connector. Fit the CPA onto the connector before you attach the side impact sensor to the door and tighten bolts to 10 N.m (89 lb in). You should put back the water deflector followed by turning on the SIR system.

Reinstall the water deflector and enable the SIR system.

Secure the side impact sensor to the door and tighten the bolts to 10 N.m (89 lb in).
