11.6 Performing the regularly inspection
During the regularly inspection the following steps must be taken at
least:
• Check the housing of DTCO 1381 and KITAS 2171 visual for indi-
cations of manipulation
• Check approval mark of the DTCO 1381
• Check sealing
• Check tire size and effective wheel circumference
• Pair DTCO 1381 and KITAS 2171 "manually"
• Measure display errors
• Perform a calibration
• Check and demonstrate the proper functioning of the EC
recording equipment
• Test and demonstrate that the entire system complies with the
permissible error limits concerning distance and speed, defined
by CR (EEC) 3821/85, annex I B.
• Check existing installation plate; create a new installation plate
and seal it if necessary.
Attention!
During the regularly inspection, be absolutely certain that the DTCO
1381 is operated in the specified voltage range!
Note the legal provisions applicable in your country and check, how
the regularly inspection must be performed and whether further
tests of the EC recording equipment are prescribed within the regu-
larly inspection.
It is possible to access the calibration functions through the cali-
bration interface, the CAN bus diagnosis, or the K-Line diagnosis
without a workshop card.
Attention!
If the workshop determines with the inspection – according to
CR (EEC) 3821/85, annex I B, paragraph IV – that the housing switch
was operated or is, the law-conformal functioning of the DTCO 1381
must be proven by appropriate inspections.
The registered data starting from the last inspection must be clas-
sified as not trustworthy, until the proof of the law-conformal func-
tioning.
