Foreword
The descriptions and service procedures contained in this manual are based on designs
and methods studies carried out up to September 1998.
The products are under continuous development. Vehicles and components produced
after the above date may therefore have different specifications and repair methods.
When this is judged to have a significant bearing on this manual, supplementary service
bulletins will be issued to cover the changes.
The new edition of this manual will update the changes.
In service procedures where the title incorporates an operation number, this is a
reference to V.S.T. (Volvo Standard Times).
Service procedures which do not include an operation number in the title are for general
information and no reference is made to V.S.T.
The following levels of observations, cautions and warnings are used in this Service
Documentation:
Note: Indicates a situation, handling or circumstance which should be observed.
Important: Indicates a situation, handling or circumstance which should be emphasized
so as not to lead to personal injury or damage to property.
Caution: Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury or damage to property.
Warning: Indicates a potentially hazardous situation which, if not avoided, could result
in death, serious injury or major damage to property.
Danger: Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.

Example of wiring diagram

Example of wiring diagram

Refer to the list of contents for the designation of the
circuit diagram. If the circuit diagram designation is
boxed in with broken lines this means that the circuit
diagram is not standard on all market or vehicle
models.
Seek column.

30 Voltage battery, kl.30.

15 Voltage with starting key in drive position, kl.15.
61 Voltage when alternator charges, kl.61.
Reference arrow (for circuit diagram EA, seek column
13).
Switch, comp. no. (104).

Single lines, cables.

Relay, comp. no. (303).

Cable area and colour (0.75 mm2 blue).

Connector (CLA terminal 4).

Bulb, comp. no. (403)

A broken line box round the component number
shows that the component is not standard on all markets or vehicle models.

If the line is broken this means the cable is not standard on all markets or vehicle model.
Earth connection point no: 2. and earth terminal no: 4.
(see diagram Earth Connections).
Joint sleeve.
