Not a Prybar or Punch: A Whole New Definition of Dirty

Not a Pry Bar or Punch: A Whole New Definition of Dirty

Why is it when you need to remove a center console, jellified soda residue is holding it in place tighter than the screws?

We’ve all worked on cars that are absolutely filthy. Unfortunately, it happens all the time. Not only are they gross, but sometimes they’re just full of stuff! How often have you needed to get into the trunk only to find it jam-packed with everything from wet gym clothes (P.U.) to a year’s worth of plastic grocery bags? Or, how often have you put the sun visor down on a test drive, only to have seven months’ worth of mail and receipts dump into your lap?

Then there’s the time a car was towed in, and it appeared the fuel pump may have gone bad. Access to the pump was gained through a panel in the trunk on this particular car, but why did it sit so low in the back? It turns out the owner was an encyclopedia salesman, evidently stocked up for the week. Ugh!

But that’s all child’s play compared to the filthy ones. Banana peels and apple cores seem to be magically attracted to the area directly under the driver’s seat, and they release a really nice pungent funk after a few weeks. And why is it that every time you need to remove a center console, the jellified coffee or soda-pop residue is holding it in place tighter than the screws?

I once had the idea to incorporate fast food with the automotive business. All I would have needed was to buy some containers and a microwave, then look under the back seat of every car that had a child seat. Then I could say to every customer, would you like fries with that? Or maybe a side of Goldfish crackers?

I was forced to scrap that idea when the local health department wouldn’t go for it. That’s when I learned the real reason technicians started wearing latex gloves. It wasn’t to protect our skin from dirt and grease, rather the occasional steering wheel that is so filthy that it’s actually sticky. Yuck!

Here’s a good one for you: the old Cadillac with a chocolate milkshake spilled on the passenger front seat. It was a brutally cold winter, and it was still frozen when I pulled the car in. The owner later confirmed that since it had been so cold, it never melted on their short drive to work, so they weren’t worried about cleaning it up right away.

I’ve never said anything to a customer about the cleanliness of their car, but I sure have formed my own personal opinions! In many cases, you wouldn’t know by the way the person dresses or acts, and I often wondered if they really realize how bad it is in their car? Then, recently, I was amused by the note a customer left on the night-drop envelope. It said, “We apologize in advance for the inside of this car and the filth. Best to leave all windows DOWN while working on it.” At least they were honest about it! Do we have the best careers or what?

I’m sure you have stories of your own. Please share them in the comments section below or send me a note to [email protected].

While systems can and will differ, here’s a look at common ADAS features, their general configurations and calibration requirements.

Advanced Driver Assistance Systems (ADAS) require the use of a scan tool for diagnostics, and the majority of the time, it’s required for post-repair calibration. ADAS, like any other system, requires a diagnostic routine, which begins with a base knowledge of the system. Knowing ADAS will help understand fault symptoms and scan tool data for the most efficient diagnosis.While systems can and will differ, here’s a look at common ADAS features, their general configurations and calibration requirements.Parking assist sensors, of which there can be more than one, are generally located in the front and rear bumpers. They are the inputs that affect active parking assist and parking collision warnings. Any time they are disturbed in any manner, a static calibration must be performed with a scan tool.Side object sensors, sometimes called collision avoidance sensors, are commonly located in the rear bumper. These sensors provide input for blind spot warnings, lane change alerts and rear cross traffic warnings. Static calibration with a scan tool is required when these are removed or replaced.Rear vision cameras will be located in the rear decklid, liftgate or tailgate, and act as either a backup camera alone, or part of a surround view system if the vehicle is so equipped. These cameras generally require a dynamic calibration, and no scan tool is required.A forward-looking camera is sometimes located behind the grille, and usually part of a surround view system. These too do not require a scan tool, but a dynamic calibration must be performed when they are removed or replaced.Different ADAS features may have dedicated control modules which can be located in various areas, often behind interior panels. As with most control modules, these require scan tool programming when replaced and, depending on the system, both static and dynamic calibrations may be required.The Haptic Seat Motor creates the vibration to provide a safety alert for blind spot, forward collision, lane departure, lane keep assist, parking collision and rear cross traffic warnings. These motors, sometimes called seat warning actuators, generally require no type of calibration.Cameras located in a sideview mirror are part of surround view systems. These require calibration when removed or replaced, but most of them dynamic, and no scan tool is required.The steering angle sensor located in the steering column is an input for lane keep assistance, and a static calibration is required with a scan tool any time it is removed or replaced, or any time a wheel alignment is performed.Last, but not least, is the front view, or forward-looking camera located in the windshield area. This camera is a vital part of adaptive cruise control, automatic emergency braking, automatic high beam headlights, forward collision and lane departure warnings, and lane keeping assistance. A scan tool and static and dynamic calibration are required after removal and replacement, but also after windshield removal or replacement, or any service that affects the ride height of the vehicle.
