Chevrolet Equinox Service Manual: Repairs and Inspections Required After a Collision Restraints Control

Accident With or Without Air Bag Deployment – Component Inspections

Warning:Proper operation of the Supplemental Inflatable Restraint(SIR) sensing system requires that any repairs to the vehiclestructure return the vehicle structure to the original productionconfiguration. Not properly repairing the vehicle structure couldcause non-deployment of the air bag(s) in a frontal collision ordeployment of the air bag(s) for conditions less severe thanintended.

After any collision, inspect the following components as indicated. If you detectany damage, replace the component. If you detect any damage to the mounting pointsor mounting hardware, repair the component or replace the hardware as needed.

The steering column—Inspect the steering column for bending, twisting, buckling orany type of damage.The instrument panel knee bolsters and mounting points—Inspect the knee bolsters forbending, twisting, buckling, or any other type of damage.The instrument panel brackets, braces, etc.—Inspect for bending, twisting, buckling,or any other type of damage.The seat belts—Perform the seat belt operational and functional checks. Refer toRepairs and Inspections Required After a Collision.The instrument panel cross car beam—Inspect for bending, twisting, buckling, or anyother type of damage.The instrument panel mounting points and brackets—Inspect for bending, twisting, buckling,or any other type of damage.The seats and seat mounting points—Inspect for bending, twisting, buckling, or anyother type of damage.The roof and headliner mounting points.The brake pedal --Inspect the brake pedal for bending, twisting, buckling or any typeof damage.Accident With Frontal Air Bag Deployment – Component Replacement and Inspections

After a collision involving air bag deployment, replace the following components.

Driver Steering Wheel Air BagPassenger instrument panel air bag, if deployedInflatable Restraint Sensing and Diagnostic Module (SDM), if the Inflatable RestraintSensing and Diagnostic Module has set DTC-B0052 and will not clearFront and/or Side Impact SensorsDriver/Passenger Seat Side Air Bag, if deployedSeat back cover if Side Seat Air Bag is deployedDriver/Passenger Seat Belt Anchor and/or Retractor Pretensioners

Perform additional inspections on the following components.

Steering wheel air bag coil and the coil wiring pigtail—Inspect for melting, scorching,or other damage due to excessive heat.Mounting points or mounting hardware for the passenger instrument panel air bag, steeringwheel air bag, Inflatable Restraint Sensing and Diagnostic Module, seat side air bag(if deployed) and seat belt anchor and/or retractor pretensioners—Inspect for anydamage and repair or replace each component as needed.Accident With Side Seat Air Bag Deployment – Component Replacement and Inspections

After a collision involving driver/passenger side seat air bag deployment, replacethe following components.

Left/right side impact sensors on the side of the impact.Left/right roof rail air bag on the side of the impact.Inflatable Restraint Sensing and Diagnostic Module (SDM), if the Inflatable RestraintSensing and Diagnostic Module has set DTC-B0052 and will not clear.Inflatable Restraint Seat Belt Anchor and/or Retractor Pretensioner.Driver or passenger seat back cushion cover replacement.

Warning:Do not repair or replace the seat stitching or seams in theseat back trim cover with an internal mounted seat side airbagmodule. Replace the complete seat back trim cover from the OEM.Non-OEM seat stitching may cause improper airbag deployment whichcould result in personal injury.

Perform additional inspections on the following components.

Mounting points or mounting hardware for the side impact sensors, and driver/passengerside seat air bags on the side of impact—Inspect for any damage and repair or replaceeach component as needed.Mounting points, mounting hardware, headliner and trim pieces for the left/right roofrail air bag on the side of impact—Inspect for any damage and repair or replace eachcomponent as needed.Mounting points or mounting hardware for the Inflatable Restraint Sensing and DiagnosticModule and seat belt anchor and/or retractor pretensioners—Inspect for any damageand repair or replace each component as needed.The seat cushion frameThe seat recliner and cover, if equippedThe seat adjusterThe seat back frameDoor trim assemblyImpacted seat cushion side covers and switchesAccident With Seat Belt Pretensioner Deployment Only – Component Replacement and Inspections

After a collision involving driver/passenger Seat Belt Retractor or Anchor Pretensionerdeployment, replace the following components.

Driver and Passenger Inflatable restraint seat belt anchor pretensioner and/or retractorpretensionerInflatable Restraint Sensing and Diagnostic Module (SDM), if the Inflatable RestraintSensing and Diagnostic Module has set DTC-B0052 and will not clear

Perform additional inspections for any damage and repair or replace each componentas needed on the following components.

Mounting points or mounting hardware for the Inflatable Restraint Sensing and DiagnosticModuleMounting points or mounting hardware for the Seat Belt Anchor PretensionersMounting points or mounting hardware for the Seat Belt Retractor PretensionersImpact Sensor Replacement Guidelines

The impact sensor replacement policy requires replacing sensors in the area of theaccident damage. The area of accident damage is defined as the portion of the vehiclewhich is crushed, bent, or damaged due to a collision. An example of this would bea moderate collision where the front of the vehicle impacts a object. If the vehiclehas an impact sensor mounted forward of the radiator, it must be replaced.

Replace the impact sensor whether or not the air bags have deployed.Replace the impact sensor even if it appears to be undamaged.

Impact sensor damage which is not visible, such as slight bending of the mountingbracket or cuts in the wire insulation, can cause improper operation of the SIR system.Do not try to determine whether the impact sensor is undamaged, replace the impactsensor. Also, if you follow a diagnostic trouble code (DTC) procedure and a malfunctioningimpact sensor is indicated, replace the impact sensor.
