Safety Information

WARNINGS:

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 multimeter battery to trigger the
activation of the module. Failure to follow this instruction may result in personal injury

NOTE: Do 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:
1. Remove the ignition key

2. Disconnect the battery leads, ground first

3. Wait 2 minutes for the power circuit to discharge

There are comprehensive instructions on the correct procedures for SRS system repairs, refer to the relevant section of the
workshop manual

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle

NOTE: Check and rectify basic faults before beginning diagnostic routines including pinpoint tests

1. Verify the customer concern by operating the seatbelt

2. Visually inspect for obvious signs of mechanical or electrical damage

Visual Inspection
Mechanical Electrical
Check for the installation of non-standard accessories which may affect or
obstruct the function of the seatbelt system
Frayed or damaged webbing
Missing or damaged button stop
Pretensioner(s) Buckles/Stalks
Fuses
Wiring harness fault
Correct engagement of electrical
connectors
Loose or corroded connections
Warning lamp bulb(s)
Impact sensor(s)
Buckle sensor(s)
Pretensioner(s)
Belt tension sensor(s)
Restraints control module
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step

4. If the cause is not visually evident, carry out the test methods described below, alternatively check for diagnostic
trouble codes and refer to the relevant diagnostic trouble code index

Inertia Reel Seatbelts

The vehicle is equipped with (two row one) and (three row two) inertia reel seatbelts
These seatbelts are "dual sensitive" which means that they have:
Car sense system - A vehicle motion sensor, which locks the seatbelt webbing under braking, cornering, on steep
hills and in adverse camber conditions, when parked on a steep incline or driveway or two wheels on a high curb
Web sense system - A webbing motion sensor, which locks when the seatbelt webbing is extracted suddenly
The seatbelts in the following positions are equipped with an automatic locking retractor function:

Activation Deactivation
NOTE: When automatic locking retractor is activated, no further webbing
can be drawn from the seatbelt retractor, prior to disengagement of the
automatic locking. This can be mistaken as a jammed seatbelt retractor
Activated by total extraction of the webbing Automatic locking retractor is deactivated by
allowing the webbing to retract until the
clicking stops (close to park position) When activated the automatic locking retractor is identified by a clicking noise
during webbing retraction When deactivated the automatic locking
retractor seatbelt changes state, from a static
seatbelt to an automatic seatbelt Seatbelt Locking Test

With the vehicle stationary and on level ground take firm hold of the seatbelt webbing (on the tongue side of the upper
seatbelt anchor) and withdraw sharply, the retractor should lock. Preventing further webbing release (repeat this test 3
times). Any seatbelt retractor which fails to lock must not be used and a new seatbelt must be installed.
