comes to a pre-repair scan, Nissan’s position is less of a requirement and more of
While the document states that both
pre- and post-repair scans are necessary
in most repair situations, Nissan recommends a pre-repair scan “where appropriate,” and acknowledges that trouble
codes can be present “even in cases where
there are no identifier lights on the dash.”
Nissan also released several additional position statements on specific
resets, calibrations and initializations.
A position statement addresses bumper
cover replacement guidelines on vehicles
equipped with sonar.
American Honda has the most com-
prehensive position statement to date.
In addition to diagnostic scanning, the
three-page document addresses calibra-
tion, aiming, inspection and reset re-
quirements. Honda doesn’t simply state
that scanning and calibration be per-
formed in a collision repair, the manu-
facturer elaborates on the what, why and
when. A section called, “Background on
Scan Requirements,” explains why diag-
nostic scanning is necessary and the fact
that dashboard indicators are insufficient
and not intended for vehicle diagnostics.
American Honda’s position is that all
vehicles involved in a collision must have
a pre-repair and post-repair diagnostic
scan. According to the statement, “a collision is defined as damage that exceeds minor outer panel cosmetic distortion.” At
first glance it appears that this definition
is somewhat subjective. With a full read
of American Honda’s position statement,
the insurer or repairer can create hard and
fast rules to make the process less subjective. Based on other listed criterions, a
vehicle with a small dent or scrape in an
outer panel may still qualify for scanning.
Same goes for inspection, calibration, ini-tialization and aiming. So, read carefully.
The position statement of Honda Canada, Inc. is essentially the same as that of
American Honda, most notably the company name is changed along with a handful of descriptor words.
All Toyota, Lexus and Scion models ap-
ply to CRIB 2016-191 released by Toyota
Motor Sales, USA in late July. Similar to
American Honda and Nissan, the docu-
ment states, “Not all DTCs illuminate a
MIL (Malfunction Indicator Light).” The
automaker “strongly recommends” a pre-
and post-repair “Health Check” diagnos-
tic scan be performed on every repair.
Per CRIB 191, “Toyota requires that
repairers perform a ‘Health Check’ diagnostic scan if a vehicle has sustained damage as a result of a collision that may affect
electrical systems.” This does not imply
that the decision is a simple matter of
personal opinion. In situations where the
physical damage does not make it obvious
that an electrical system may be affected,
critical thinking skills should be utilized
to make that determination. Specific vehicle equipment knowledge, proximity of
sensitive components to the impact zone,
OE repair manual information, training
and consumer input factor into the process at times or in the aggregate.
Although some positions appear focused on collisions, it seems unreasonable
