Keeping up with the latest vehicle technology can be challenging
these days – numerous control modules, alternative materials, new
construction techniques and just plain tricky engineering — just
to name a few!
I’d like to focus on the top-five collision repairs that many
body shop techs are currently viewing in
Hopefully, these valuable insights will help you with some of
your next repairs. Maybe you have already experienced a few of
these issues. Do any of them sound familiar?
Door Pressure Side-Impact Sensors
You have repaired damage to the front driver’s side door on a
2013 Sonata and replaced the airbag and side impact sensor. After
clearing any fault codes, the airbag light is still glowing.
Unlike many side-impact systems that use acceleration and
side-impact sensors to activate the side air bags, this vehicle
is also equipped with two pressure side-impact sensors that sense
an air pressure change caused by a distorted door at the time of
a collision. The SRSCM (Supplemental Restraint System Control
Module) detects the impact signals of the pressure side-impact
sensor to help determine which airbag to deploy.
Verify that your techs are properly reassembling these doors
after they perform their removal and installation operations. The
repaired door must be airtight. Anything that compromises proper
pressure within the door will generate a fault code. Something as
insignificant as a broken clip may be the culprit.
Front Door Skin Panel
If you have ever had to perform this repair, you understand why
factory information is extremely helpful in getting it repaired
right the first time.
Removal of the door skin panel begins with grinding it off along
the perimeter of the door. Then, the original adhesive residue
must be trimmed off with a utility knife. Replacement requires
bonding the panel with adhesive and MIG welding in two spots. The
manufacturer covers these procedures in great detail and should
be followed to the letter for a safe, reliable repair.
2014 Jeep® Grand
Frame Sectioning Caution
Chrysler® says to
eliminate the heat when working on the new Jeep Grand Cherokee.
Chrysler uses an extensive amount of high strength steels in all
of their vehicles and warns that when repairing all body panels
or frame components, the “cold straightening” method must be
used. What’s the reason? High-strength materials can be
substantially and negatively affected from heat input which will
not be obviously known to the repairer or consumer. Ignoring
these recommendations may lead to serious compromises in the
ability to protect occupants in a future collision event, reduce
the engineered qualities and attributes, or decrease the
durability and reliability of the vehicle. Be sure to refer to
ALLDATA Collision for OEM sectioning, repair and precautionary
Quarter Panel Sections
Unlike Chrysler, Toyota recommends heat for removing and
replacing the quarter panel on a Corolla. The procedure cautions
against using too much heat, which may deform the panel. Removal
and replacement of the quarter panel is not easy. It involves
adhesive, body sealer and the three welding procedures: plug,
spot and butt. Pay attention to all the details for a quality
Bumpers are a lot more complex to replace today than ever before.
For example, the bumper/grille assembly on a 2014 Chevy Silverado
includes a “shutter” component designed to close when the need
for engine cooling is reduced. When driving on the freeway, the
shutters may close down to increase the truck’s aerodynamic
qualities and performance. It’s mainly aimed at boosting gas
mileage. The OEM removal procedure warns us to “carefully”
disassemble links, tabs, electrical connectors, actuators and
louvers. The same care should be used when reassembling these
