Foreword
The descriptions and service procedures contained in this manual are based on designs
and methods studies carried out up to April 2005.
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 procedure, practice, or condition that must be followed in order to have
the vehicle or component function in the manner intended.
Caution: Indicates an unsafe practice where damage to the product could occur.
Warning: Indicates an unsafe practice where personal injury or severe damage to the
product could occur.
Danger: Indicates an unsafepractice where serious personal injury or death could occur.

Malfunction
Tachograph, fault codes, general information
When there is an fault in the tachograph system, a fault
code is normally stored in the tachograph unit. When the
fault is active, this is shown in the tachograph display.
Note: The tachograph does not handle fault codes in the
same way as the vehicle’s other control units. Fault codes
are displayed as illustrated.
T3017893
Error messages forfaultcodes are shownas follows:
1 Pictograms or pictogram combinations (specified
in accordance with legal requirements)
2 Informative text
3 Fault code number
The background flashes for 30 seconds or
until a button is pressed.
Note: Tachograph fault codes are shown on the
tachograph display. However, the driver is made aware of
any messages and warnings by a warning lamp.
T3017898
Note: The fault codes are used as indicators when
troubleshooting. This does not mean that the tachograph
needs automatically to be changed if there are fault codes
stored.

Internal fault.
Conditions for fault code:
A serious fault has occurred in the tachograph, or there
•
is a communication fault between the tachograph and
the programming tool.
Possible causes of faults:
The position of the starter key has been changed
•
during calibration.
Interruption of the feed voltage to the tachograph or
•
the programming tool.
Loose connections or fault in the wiring between the
•
tachograph and the programming tool.
Appropriate action:
Check the programming tool connector and wiring.
•
Check the power supply to the tachograph and the
•
programming tool.
If the fault code remains, without apparent cause, change
the tachograph.
