Reading and Clearing Diagnostic Trouble Codes

Flash codes

Self check
1. Turn the ignition switch to the ON position.
2. Observe the airbag warning light function.
- Warning light ON solid for six seconds.
- Warning light goes off and stays off.

Fault on system
3. Turn the ignition switch to the ON position.
4. Observe the airbag warning light function.
- Warning light ON solid for six seconds.
- Warning light goes off for two seconds.
- Warning light flashes the appropriate number of times for the fault logged (see below).
- Warning light goes off for two seconds.
- The sequence is repeated five times.
- Warning light stays ON until the ignition is switched OFF.

Example
Flash code 16 would be shown as lamp ON for one occurence of 0.5 seconds, then lamp OFF for one second, followed by six occurences of lamp flashing ON/OFF for 0.5 seconds each (1 - 6).

Poor Retraction

WARNING:
- In the event of an incident in which the air bags have been deployed, ALL safety belts that were in use at the time of the incident must be removed and new safety belts must be installed. Failure to follow this instruction may result in personal injury.
- After five incidents involving the deployment of SRS components, the restraints control module must be replaced. Failure to follow this instruction may result in personal injury.

If a safety belt does not retract correctly, check that the anchor covers and trim bezels are correctly installed and not rubbing against the safety belt webbing. Where necessary, check that the safety belt webbing is not rubbing at one end of the retractor cover slot and , if so, correct by loosening the retaining bolt, aligning the retractor to centralize the safety belt webbing and retighten the bolt.

The vehicle is equipped with two front and three rear inertia reel safety belts. These safety belts are dual sensitive which means that they have:
- a vehicle motion sensor, which locks the safety belt webbing under braking, cornering, on steep hills and in adverse camber conditions.
- a webbing motion sensor, which locks when the safety belt webbing is quickly extracted.

Both systems should be fully operational and can be checked by the tests below.

Vehicle Motion Sensor Test
Either of the following two procedures may be used to check correct operation of the vehicle motion sensor.

Both methods require two people, but note that people of larger than normal size should not be asked to conduct these tests. This is to avoid the possibility of a fully unrolled safety belt webbing being mistaken for a correctly locked safety belt retractor.

Test Method 1 (braking)

WARNING: It is important that during this test, the wearer allows the safety belt to provide the restraint, the wearer should not attempt to anticipate the sudden deceleration. However, both the driver and the passenger must prepare themselves for the possibility that the safety belt will not lock. Failure to follow this instruction may result in personal injury.

- Select a suitable road. Make sure that the road is clear and that full visibility is maintained at all times.
- Both driver and passenger should adopt normal, comfortable seating positions, with safety belts worn in a normal fashion.
- Do not exceed 6 mph (10 km/h) for this test.
- Make sure that all passengers are aware of when the driver will brake.
- Apply the foot brake sharply to stop the vehicle. If the vehicle motion sensitive lock mechanism is operating correctly, the safety belt webbing will lock and restrain the wearer.
- Conduct the test twice in each front and rear passenger seat position.
- Any safety belt retractor which does not restrain the wearer during this test must not be reused. A new safety belt must be installed.

Test Method 2 (turning circle)
This method requires a flat open area, sufficient for the vehicle to be driven in a continuous circle on full lock.
- The passenger should occupy a rear seat with the safety belt correctly adjusted.
- With the steering on full lock, drive the vehicle in a continuous circle at 10 mph (16 km/h). Do not exceed 10 mph (16 km/h).
- When the speed is stable, the passenger should attempt to slowly extract the safety belt webbing from each safety belt retractor in turn. If the vehicle motion sensitive lock mechanism is operating correctly, it will not be possible to extract the webbing.
- Any safety belt retractor from which it is possible to extract the webbing during this test must not be used. A new safety belt must be installed.

Safety Belt Webbing Sensor Test
With the vehicle stationary and on level ground take firm hold of the safety belt webbing and pull out quickly. The retractor should lock within 0.25 metre (10 inches), preventing further webbing pay out. Any safety belt retractor from which it is possible to extract further webbing must not be used. A new safety belt must be installed.
