Overview

The information in this section is intended to help with basic diagnosis of the safety belt system.

For information on the description and operation of the system:

The safety belt system forms part of the restraint system overall. so there is some cross-over with the supplemental restraint section of the manual, certainly as far as diagnostic trouble codes are concerned.

Given the potential for damage/injury, the preferred method of diagnosis is the approved diagnostic system, and even when using this, the following safety information should be followed at all times:

Safety information

: To avoid accidental deployment the back-up power supply must be depleted before beginning any work on the SRS system or its components. Failure to follow this instruction may result in personal injury.

: Do not use a multimeter to probe an SRS module. It is possible for the power from the meter battery to trigger the activation of the module. Failure to follow this instruction may result in personal injury.

It is advisable not to use a cellular phone or to have a cellular phone in close proximity when working on the SRS system or components.

Power supply depletion

Before beginning any work on the SRS system or related components:

. Remove the ignition key.

. Disconnect the battery leads, ground first.

. Wait 2 minutes for the power circuit to discharge.

There are comprehensive instructions on the correct procedures for SRS system repairs in the manual:

Inspection and Verification

. Verify the customer concern.

. Visually inspect for obvious mechanical or electrical faults.

Mechanical	Electrical
Check for the installation of non-standard accessories which may affect or obstruct the function of the SRS system Frayed or damaged webbing Buckles/Stalks, etc Reels Sensor(s) Pretensioner(s)	Fuses Battery junction box (BJB) - fuse 11E Central junction box (CJB) - fuse 9P Central junction box (CJB) - fuse 68P Wiring harness Warning lamp bulb(s) Impact sensor(s) Buckle sensor(s) Pretensioner(s) Restraints control module (RCM)

. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

Faults in SRS harnesses would normally mean replacement of the relevant harness. SRS harness repairs are not recommended

. Use the approved diagnostic system or a scan tool to retrieve any DTCs before moving onto the dynamic checks or the DTC index.

Make sure that all DTCs are cleared following rectification.

Dynamic checks

Either of the following two procedures may be used to check the correct operation of the safety belts. Both methods require two people but note that people of larger than average 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)

: 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 and the driver should not brace themselves against the steering wheel. However, both the driver and the passenger must prepare themselves for the possibility that the safety belt will not lock. The passenger should hold their hands in front of them, just clear of the instrument panel or front seat backrest, depending on which belt is being tested. Failure to follow these instructions may result in personal injury.

Select a quiet or private stretch of road. Make sure that the road is clear and that full visibility is maintained at all times.
Both driver and passenger should adopt a normal, comfortable seating position. Both occupants should wear the safety belts and the safety belt webbing should be correctly adjusted.
Proceed at a speed of approximately 10 km/h (6 miles/hour). Do not exceed 10 km/h (6 miles/hour) for this test
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 should be installed.

Test Method 2 (Turning circle)

This method requires a flat open area of private road, sufficient for the vehicle to be driven in a continuous circle on full lock.

The driver should wear the safety belt provided and the belt webbing should be correctly adjusted.
The passenger should occupy a rear seat with the safety belt correctly adjusted.
Start the engine and, with the steering on full right-hand lock, drive the vehicle in a continuous circle at 16 km/h (10 miles/hour). Do not exceed 16 km/h (10 miles/hour) for this test
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 should be installed.

Safety Belt Webbing Sensor Test

With the vehicle stationary and on level ground take firm hold of the safety belt webbing (on the tongue side of the upper safety belt anchor) and pull out quickly. The retractor should lock within 0.25m (10 inches), preventing further webbing release. Any safety belt retractor from which it is possible to extract further webbing must not be used. A new safety belt should be installed.

DTC index

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the manufacturer-approved diagnostic system).
