Functional Test - Safety Belt Buckle and Tongue

NOTE: Make sure the safety belt buckle and tongue assembly operate freely during the latching and unlatching function. Fasten the safety belt by inserting the tongue (male portion) into the buckle (female portion).

Verify the following during the latching sequence:

Tongue insertion does not require excessive effort.
A click is heard when the safety belt buckle latches the tongue.

Verify the system integrity by forcefully pulling on the safety belt webbing.

Unlatch the safety belt by fully pressing the safety belt buckle release button and allowing the safety belt to release and retract.

Verify the following during the unlatching process:

Pressing the push button does not require excessive effort.
The tongue can be removed easily from the buckle.

Repeat the above steps 3 times.

If the functional test reveals a concern(s), install a new safety belt buckle or safety belt retractor as required.

Functional Test - Safety Belt Retractor

NOTE: Make sure the safety belt retractor is freely operational for extraction and retraction of the safety belt webbing between full extension and in-vehicle stowed positions.

Extract and retract the safety belt between the full extension and stowed positions.

Verify the safety belt retractor operates without excessive effort or binding.

Install a new safety belt retractor if any concern is found or the complaint has been verified.

Functional Test - Safety Belt Retractor, Automatic Locking Retractor (ALR) Mode

Position the seat backrest fully upright (if adjustable).

Position the safety belt shoulder height adjuster (if equipped) in the full down or up position.

Fasten the safety belt.

Pull out the safety belt webbing until the Automatic Locking Retractor (ALR) feature is activated.

Allow the safety belt webbing to retract until it stops.

Pull on the safety belt webbing to make sure the safety belt retractor has remained in the Automatic Locking Retractor (ALR) mode. If the safety belt retractor is not locked, install a new safety belt retractor.

Unfasten the safety belt and allow the safety belt webbing to retract to its stowed position.

Pull out and retract the safety belt webbing to verify the safety belt retractor has converted automatically out of Automatic Locking Retractor (ALR) mode. If the safety belt retractor remains locked in the Automatic Locking Retractor (ALR) mode, install a new safety belt retractor.

Functional Test - Safety Belt Retractor, Road Test Inspection

NOTE: Make sure there is no excessive slack in the safety belt webbing across the torso during testing.

NOTE: Do not jerk on the safety belt webbing when carrying out this test.

Fasten the safety belts and proceed to a safe area.

Reach a speed of 24 km/h (14.9 mph).

WARNING: Apply maximum brake force only on dry concrete or equivalent hard surface, never on wet pavement or gravel. Failure to follow this instruction may result in serious personal injury.

Grasp the shoulder harness, lean forward and apply the brakes, making a maximum braking application without a skid.

The safety belts should lock up with minimum webbing extension.

If there is a lockup of all safety belt retractors being tested, the safety belt retractors are functioning correctly. If any safety belt retractor fails to lock up, install a new safety belt retractor(s).
