5 Troubleshooting
5.1 Handling error situations
Indicator lights and service codes guide you in error situations.
•
Take notice of the indicator lights on the instrument panel and act
accordingly.
The STOP indicator light starts flashing. • Stop the tractor and the engine immediately.
• Continue only in an emergency, for example,
to move the tractor to the roadside.
The book symbol starts flashing on the A-pillar
display to indicate an active service code in the
system.
• Contact an authorised Valtra workshop
immediately.
The limiting function of the maximum engine
speed is on (for example, 1 500 rpm or 1 800
rpm).
Some service codes limit the maximum engine
speed, torque and power of the engine or
shutdown the engine after a delay of
approximately 30 s. This prevents serious damage
to the engine.
• Avoid long-term and heavy use of the engine
until the error is fixed.
NOTE: If the book symbol starts flashing, contact an authorised Valtra
workshop, even if the error does not prevent driving the tractor.
