SECTION 1A7 - SEAT & SEAT BELT ASSEMBLIES

CAUTION:

This vehicle will be equipped with a Supplemental Restraint System (SRS). A SRS will

consist of either seat belt pre-tensioners and a driver's side air bag, or seat belt pre-

tensioners and a driver's and front passenger's side air bags. Refer to CAUTIONS,

Section 12M, before performing any service operation on, or around any SRS

components, the steering mechanism or wiring. Failure to follow the CAUTIONS

could result in SRS deployment, resu lting in possible perso nal in jury or u nnecessary

SRS system repairs.

CAUTION:

This vehicle may be equipped with LPG (Liquefied Petroleum Gas). In the interests of

safety, the LPG fuel system should be isolated by turning 'OFF' the manual service

valve and then draining the L PG service lines, before any service w ork is carried out

on the vehicle. Refer to the LPG leaflet included with the Owner's Handbook for

details or LPG Section 2 for more specific servicing information.

1. GENERAL DESCRIPTI ON

A four-way electric adjustable drivers seat (front up and down, and rear up and down) is fitted to all VT Series

Models except Calais Models. Calais models are fitted with an eight-way electric adjustable front passenger and

drivers seat (front up and down, rear up and down, forward and rearward (fore/aft), and reclining).

The four-way electric driver’s seat contains two electric, reversible motors. The front and rear heights of the seat are

controlled by separate lift motor and gearbox assemblies. Each motor can be operated independently of each other,

or operated together to raise or lower the seat.

The eight-way driver and passenger seats have two additional electric, reversible motors fitted. A separate fore and

aft movement motor and gearbox assembly controls the seats forward and rearward positioning. The fourth motor

controls the seat back reclining position.

A driver’s seat lumbar support is standard on all models, while a front passenger seat lumbar support is standard on

Acclaim, Berlina, S, SS and Calais models.

Front seat belt height adjusters provide the ability to raise and lower the seat belt from the shoulder for additional

comfort and are fitted as standard equipment on Calais.

The front seat belts also come, as standard equipment, with pyrotechnic seat belt pre-tensioners. These pre-

tensioners are connected into the SRS and are designed to restrain potentially fatal body movements upon impact

in a collision. Seat belt pre-tensioners work in conjunction with standard inertia reel seat belt retractors with webbing

clamps. For principles of operation and diagnosis of the seat belt pre-tensioner system, refer to

Section 12M SUPPLEMENTAL RESTRAINT SYSTEM.

NOTE:

If a seat belt pre-tensioner is deployed, the seat belt pre-tensioner assembly together with the seat adjuster,

guide rail assembly and control module (SDM) must be replaced.

The seat covers (except leather trim option) for the front seat back and cushion, and rear seat back and cushion

are bonded to the pad material. If the there is a need to replace the seat cover on any of these components, they

must be replaced as a cover and pad assembly. Only the covers for the rear seat armrests are replaceable as sub-

assemblies (separate cover and pad assembly).

All models feature access to the rear compartment through the rear seat back, either when the fold down tray is

lowered for sedans or via the 60/40 split rear seat on wagon models.

Techline

1.1 ELECTRIC SEAT ADJUSTMENT

WARNING:

For reasons of personal safety, the vehicle

must only be driven when the seat is adjusted

to the correct driving position. Do not adjust

the driver’s seat when the vehicle is moving as

the seat could move away from the driving

position, causing loss of control.

SEAT CONTROL ADJUSTMENT SWITCH ASSEMBLY

A seat control adjustment switch is fitted to the

outside of eac h seat fr am e where electric seats are

fitted. This switch assembly provides independent

control of:

1. Horizontal switch - f ront and rear height (up and

down movement) of seat, and on vehicles with

the eight way electric seats, this switch also

provides fore/aft movement.

2. Vertical switch (eight-way electric seats only) -

seat recliner angle.

Figure 1A7-1

To control the seat front and rear heights, and the

fore and aft movements, the appropriate electric

mo tor and gear box ass embly is driven which dr aws

in or extends out a mating worm shaf t which in turn

operates either the cross bar, for up and down

movement, or the seat guide rail for fore/aft

movem ent. By reversing the polarity of each of the

motors terminals, causes the motor to drive in the

reverse direction and therefore the seat will move

in the opposite direction.

The seat back recliner angle on Calais models is

adjusted by a recliner motor attached to the inner

seat back f ram e. T he m otor has a drive gear which

is meshed with a driven gear attached to the seat

back frame. Motor operation causes the rotation of

the drive gear which turns the driven gear and seat

back frame, thereby altering the seat back recliner

angle. Reversing the polarity of the recliner motor

terminals causes the motor to drive in the reverse

direction and the seat back moves in the opposite

direction.

3. DIAGNOSTICS

3.1. PREREQUISITES TO DIAGNOSIS AND TROUBLE SHOOTING

PRELIMINARY SYSTEM REQUIREMENTS

The prerequisites before proceeding with system checks are:

• Fusible link FJ and circuit breaker F2 must be checked before any electrical diagnostic checks are performed.

• Ensure no moisture is present in the main wiring harness to body wiring harness or seat harness connections.

• Ensure that sound earth connections are available for all functioning components.

• Ensure the battery is in good condition and adequately charged (above 11.5 Volts) before carrying out any

electrical checks.

SAFETY REQUIREMENTS

Disconnect the battery when carrying out work which involves the risk of an electrical short circuit.

Do not touch mechanical components during function checks, to avoid the risk of a hand being caught in the

mechanism.

CHECKING EQUIPMENT

An unpowered testlamp with a current draw of less than 3 Amps.

A digital multimeter, with a minimum 10 Megohm impedance MUST be used when undertaking any electrical

checks on these systems.

Exercise care when taking readings from wiring harness connectors. It is preferred that the back probing method

with individual connectors is employed wherever possible, to avoid terminal damage and subsequent connection

failure.

When carrying out wiring checks as directed to by the diagnostic charts, rather than probe terminals and connectors

with incorrect sized multimeter connections, use the adaptors contained in connector test adaptor kit KM-609. This

will prevent any possibility of spreading or damaging wiring harness terminals.

IMPORTANT:

• When checking, the exact order of the test steps should be observed.

• If the required nominal value is not achieved in any stage, then the problem must be rectified before

proceeding further.

• Unless the multimeter being used has an auto ranging function, check that the correct range, as specified, is

selected before the test is carried out.

3.2 VISUAL INSPECTION

When investigating any complaint of an electric seat problem or malfunction, start diagnosis with a visual inspection

of the system.

The visual inspection procedure may quickly identify the cause and illuminate the need for additional diagnosis, in

particular if the problem is a mechanical fault.

If the complaint condition can not be resolved by the visual inspection, proceed to the appropriate diagnostic chart in

this Section.

NOTE:

Diagnostic charts 3.3 to 3.7 in this Section relate to electrical faults only and assume there are no mechanical faults.

ELECTRIC SEAT VISUAL INSPECTION

GENERAL

ITEM INSPECT FOR CORRECTIVE ACTION

Operation of seat (noisy,

slow or no Foreign material causing seat to

bind. Remove foreign material.

operation at all). Dry components, build up of dirt

on moving components. Clean and apply Lithium

based grease (to Holden

specification HN 2073) to

noisy component.
