Technical Messages And Errors - Volvo FM Handbook

384 Alcolock
Your VOLVO ALCOLOCK is safe to use in ADR—
applications. Always make sure that an ADR
compatible handset is used.
Newer non ADR compatible ALCOLOCK V3
handsets will temporarily display "ADR incompatible"
when they are first connected along with a warning
tone. These handsets will operate correctly, but the
vehicle will no longer be allowed to transport
hazardous goods.
3 Other errors
The handset may not accept a breath test for various
reasons and messages such as Invalid Sample,
Cancelled Try again, communication error, RF (radio
frequency) detected, Incorrect or Low voltage. To
minimize errors, ensure that the handset is connected
properly and cabling, connectors and vehicle battery
are in good condition. Turn mobile phones off.
Attempt the test again.
4 If the ALCOLOCK should brake
If there is any problem to start the truck after a stand
still, the ALCOLOCK can be over rided with a 4-digit
code. This code is available at Volvo Action Service.
The code is changed every day and should not be used
for a long time. The truck should be taken to the
workshop so the ALCOLOCK can be repaired.

Technical messages and errors

1 Clock Error
The VOLVO ALCOLOCK receives its time signal
from the vehicle's tachograph. Should the tachograph
fail or be removed for servicing, a "Clock error"
message will be displayed for several seconds. The
handset will operate correctly, but dates will not be
correctly displayed until a properly functioning
tachograph is connected.
2 Technical Error
Should the handset detect an internal power failure
"Technical error" will be displayed.
