Sometimes it’s the little things that trip you up. You apply all
of your knowledge, talent, time and energy to restoring a vehicle
to like-new condition after it has been in a collision. You’re
ready to deliver the car to the customer, but one of the
headlamps, of all things, won’t illuminate. Or, the vehicle owner
drives off but comes back a short time later complaining of a
noise coming from one of the wheels.
Your margin on this job is already slim, and now you need to
spend more time making sure the vehicle is safe and meets your
standards of quality. Of course, you also want to make sure your
customer drives away happy because you know that satisfied
customers are one of your most valuable forms of advertising.
Stop sweating the small stuff. The key to avoiding many minor yet
frustrating scenarios is information – specifically, OE
information. After all, it goes without saying that the best
source of repair information is the manufacturer that built the
vehicle in the first place.
The benefits of having access to OE collision information are
Improved estimate accuracy
Less wasted time ordering the wrong parts
When OE mechanical procedures are included, you can also benefit
Greater control over the repair schedule
And there is at least one more benefit to having OE repair
information at your fingertips: up-to-date Technical Service
Bulletins (TSBs). TSBs describe known issues with a vehicle,
along with detailed procedures for fixing them. They can protect
you when a vehicle owner brings back the car that you just
repaired and tells you there’s a problem with your work. A quick
check of your TSBs might just show that the condition was
pre-existing. It happens! TSBs also provide you with the
opportunity to earn revenue fixing something unrelated to
Here are excerpts from two TSBs for Infiniti vehicles, one for
wheel bearing damage and the other related to the tire pressure
monitoring system (TPMS).
Always refer to ALLDATA Collision for safety procedures,
identification of material types, recommended refinish materials,
removal and installation procedures. Always refer to the
manufacturer for questions relating to applicable or
non-applicable warranty repair information.
Condition – Wheel Bearing Damage
Impacts to wheel bearings (such as a collision or other
suspension damage) may create slight indents in the bearing
surfaces. These indents may not be visible but can cause bearing
NOTE: Hub/bearing replacement due to impact (collision or other
suspension damage) is not a warrantable repair. If a vehicle has
visible wheel or suspension damage due to impact (collision or
other suspension damage), it’s recommended that the wheel bearing
assembly be inspected as follows:
Remove the hub/bearing assembly from the vehicle.
Hold the hub/bearing assembly with both hands.
Rotate the hub/bearing assembly in both directions (clockwise
If any gritty or rough feeling is detected in the bearing,
replace it with a new one.
Condition – TPMS
If you confirm the TPMS warning light is illuminated, steady or
flashing, take the following steps:
Turn ignition to the OFF and then ON position (engine not
required to be running).
If the TPMS warning light is illuminated steady (not
flashing), the TPMS is operating normally and has detected
low tire pressure in one of the tires. Go to Step 2.
Normal tire pressure maintenance is not covered under
Some 2011 models will display an alert in the vehicle
information display near the speedometer. The alert will read
“Check Tire Pressure” and will accompany the illuminated TPMS
If the TPMS warning light is flashing for approximately
one minute, there is a TPMS system malfunction. Do not go to
Step 2. Instead, check the DTC and refer to the repair
Leave the ignition in the “ON” position* (engine is not
required to be running) and set the tire pressure to the
recommended pressure. *Leaving the ignition in the ON position
may allow the TPMS to detect the corrected tire pressure more
quickly on 2009 and newer models without having to drive the
Each vehicle is equipped with a “Tire and Loading Information”
placard. For factory-equipped tires, follow the recommended cold
pressure on the placard to set the tire pressure on the vehicle.
Tire pressure can be affected by factors such as tire
temperature, outside temperature, time and altitude. When tire
pressure is low, make sure it is not caused by a leak. If needed,
repair as necessary.
After tires are inflated to the recommended pressure, the vehicle
may need to be driven at speeds above 16 mph for the TPMS to turn
off the low tire pressure warning light.
