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 air bag, seat belt pre-tensioners and a driver's and front

passenger's air bag s or seat belt pre- tensio ners, d riv er’s and fron t p asseng er’s air bag and lef t and rig ht

hand side air bags. Refer to SAFETY PRECAUTIONS, Section 12M Supplemental Restraint System of

this Service Information CD before performing any service operation on, or around any SRS

components, the steering mechanism or wiring. Failure to follow the SAFETY PRECAUTIONS could

result in SRS deployment, resulting in possible personal injury or unnecessary 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 LPG

service lines, before any service work is carried out on the vehicle. Refer to the LPG leaflet included with

the Owner's Handbook for details or the appropriate Section of this Service Information CD for more

specific servicing information.

1. GENERAL DESCRIPTI ON

Since the VT Series Service Information CD was first published, there have been several changes to the seats. The

information contained in this Section provides a summary of these changes, together with any relevant Service

Operations, Diagnostic Procedures and Specifications.

Noting the following Cautions, information, including General Description, Service Operations, Diagnosis,

Specifications and Special Tools, that is not covered in this Section, refer to Section 1A7 SEAT & SEAT BELT

ASSEMBLIES of the VT Series I Service Information.

Thes e following Cautions apply to Service Operations detailed in both this Sec tion and thos e pr eviously published in

Section 1A7 SEAT A ND SEAT BELT ASSEMBLIES of the VT Series I Service Information.

CAUTION: Before performing any Service Operation on a front seat assembly, ensure the SRS is disabled.

Refer to Section 12M SUPPLEMENTAL RESTRAINT SYSTEM of the VT Series I Service Information.

CAUTION: Accessory and after market seat covers MUST NOT be fitted to a vehicle with side impact air

bags unless approved by Holden Ltd. Seat covers that are not approved by Holden Ltd. could greatly inhibit

the performance of the side impact air bag and occupants safety in the event of side impact air bag

deployment.

SUMMARY OF CHANGES

In August 1998, side impact air bags became available as an option to VT Series Models. With the availability of this

option, a revised procedure for disassembling and reassembling the front seat has been developed.

For additional information, including the removal and reinstallation of a side impact air bag module assembly,

refer to Section 12M SUPPLEMENTAL RESTRAINT SYSTEM of the VT Series I Service Information.

New lumbar support knob for vehicles with side impact air bags.

NOTE: If a lumbar support knob requires replacement, and the vehicle is equipped with side impact air bags,

only install this new type lumbar support knob which has been modified to suit side impact air bag applications.

New seat fabrics / colours for VT Series II Models.

Since the start of VT Ser ies vehicle production, var ious fas tener types and tor que wrench s pecifications have been

revised. Therefore, 4. TORQUE WRENCH SPECIFICATIONS in this Section has been revised to reflect these

changes and re-published in full. Whenever tightening a seat or seat belt fast ener on a VT Series Model, referenc e

to this Section should be made.

From vehicle Tag Number L423680 there was a revision to the wiring on the four way seat electric motors.

Previously, the electric seat motors were constantly supplied with power and connected to earth to activate. With

this wiring revision, the seat m otors ar e constantly earthed and connected to battery voltage to activate. As a result

of this change, there have been some revisions to the diagnostic procedures, refer to 3. DIAGNOSTICS in this

Section.

NOTE: The wiring of the eight way electric seat remains unchanged. Eight way electric seat m otors are constantly

earthed and connected to battery voltage to activate.

3. DIAGNOSTICS

NOTE: The following diagnsotic procedures only relate to vehicles built after Tag Number L423680 fitted with the

four way electric seat.

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.

If the vehicle is equipped with side im pact air bags, bef ore removing any components on or around the front seats ,

disable the SRS, refer to Section 12M SUPPLEMENTAL RESTRAINT SYSTEM of this Service Information CD.

CHECKING EQUIPMENT

An unpowered testlamp with a current draw of less than three 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 chec k s as directed to by the diagnostic c harts , r ather than pr obe terminals and c onnec tors

with incorrect sized m ultimeter connec tions, use the adaptors contained in c onnector 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 elec tr ic s eat pr oblem or malf unc tion, s tart diagnos is with a vis ual inspec tion

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 Chart 3.3, Diagostic Chart 3.4 and Diagnostic Chart 3.5 in this Section relate to electrical

faults only and assume there are no mechanical faults.
