Let's bring attention to when diagnostic, scanning and calibration services are needed and the state of repair the vehicle needs to be in to accurately perform testing, scanning or calibrations. To do this, I’m going to break it down into four parts: diagnostics, pre-repair scans, post-repair scans and calibrations. It is through technical knowledge and hands-on experience that I draw on to try to give some insight to help the repair process proceed more smoothly.

ENTER CODE : EHYBRID AT CHECKOUT
A large portion of the work done at my company, Mobile Auto Solutions (MAS) is diagnosing malfunctions. One such case was a Toyota Sienna that had a sliding door that did not work with the key fob. When I arrived at the shop, they showed me the car (Figure 1). While I understand the shop wants to ensure everything is working before assembly, I told the shop I would not even scan the vehicle. I knew that having the front door off would cause issues with the other doors and locks working correctly. This comes from experience and knowing that the vehicle will have issues caused by the disassembly. I can only imagine the pain a remote company would have had — an individual sitting in Texas not knowing the state of disassembly looking at scan data and chasing his/her tail. The point is that many systems will not work when a vehicle is in the repair process. Having a check-in process that includes a pre-repair scan is the best way to enter into the repair.
I recently read an article explaining how scans could indicate if issues were loss-related by using freeze frame data. I had mixed feeling about the information; I was worried shops and insurance companies would think that this data is available on all vehicles and for all modules. The data described was data that is helpful when diagnosing an emission- or engine-running problem. It is not very often that this data will be helpful in determining if the code is loss-related. So, for the shop considering whether or not to have pre-repair scans performed, please allow me to share some insights. MAS services more than 1,300 shops in the Chicago, Northwest Indiana, Milwaukee and Grand Rapids areas. We get to experience many different ideas of what a pre-repair scan is. Some shops just want to know about deployed items or other warning light issues. Other shops use pre-repair scans as a way of making sure the vehicle is repaired correctly while protecting the shop and the insurance company from unrelated costs. Regardless of which of these your shop is considering, the scan needs to be performed before any form of repair has begun. If the vehicle is in a disassembled state like the Honda in Figure 2, it’s nearly impossible to know if some codes are loss-related.
