Operation CHARM: Car repair manuals for everyone.

Component Tests and General Diagnostics

CAUTION: Perform this test in an area clear of other vehicles or obstructions. Do not conduct this test on the open road. A large, empty parking lot is suitable. Failure to observe this precaution may result in damage to the vehicle and possible personal injury.

CAUTION: Replace belts, retractors, and hardware in use during all but a minor collision. Also, restraint systems should be replaced and anchorages properly repaired if they were in areas damaged by collision, whether the belt was in use or not. If there is any question, replace the belt system. Damage, whether visible or not, could result in serious personal injury in the event of an accident.

^ Inspect all seat belt anchor bolts to verify that they are secure.
^ Inspect the seat belt buckle, making sure it locks and unlocks easily.
^ After buckling the seat belt, tug sharply on the belt, checking that the buckle remains locked.
^ Fully extend the seat belt to make sure there are no twists or tears in it.
^ Allow the seat belt to fully retract to make sure it does so easily.
^ Fasten the seat belt.
^ Drive the vehicle at 16 km/h (10 mph) and apply the brakes firmly.
^ Verify that the seat belt locks and does not allow your body to move forward.
^ If the belt does not lock during the running test, remove the retractor and perform the static test.
