1.
if the need should arise for you to
have your vehicle serviced, the banks
ottoMind should be removed from the
engine control unit (eCu). it is common
for the service provider to connect a
computer diagnostic link to the vehicle
regardless of the type of service being
performed. when the ottoMind is
installed, the computer will return a
code that indicates a memory fault
with the vehicle eCu. the suggested
repair for a fault of this type is
replacement of the eCu.
2.
the operation of the ottoMind is
such that the computer is directed
to reference certain information in
the ottoMind rather than the eCu.
therefore, the memory fault that
occurs is not an eCu failure, but rather
the presence of an electronic device
that the diagnostic computer cannot
identify.
3.
to avoid confusion about whether
or not an eCu is properly functioning,
simply remove the ottoMind from
the eCu before having the vehicle
serviced, and reinsert the plastic cap
in the eCu access port. the ottoMind
can be easily accessed from inside the
truck, and it is unnecessary to remove
the computer from the vehicle. the
ottoMind may be reinstalled after the
service is complete.
4.
it is also not uncommon for a
service provider to update the program
in the vehicle eCu. if this occurs, it is
possible that the programming in the
ottoMind will no longer match the
eCu program. if you experience any
difficulty with the operation of the
banks ottoMind after service, check
with the service provider to determine
if an update was performed. then
contact customer service at Gale
banks engineering for an updated
ottoMind, if necessary.
