In the evolving landscape of automotive repair, the integration of technology has become paramount. Recently, two distinct experiences underscored the critical need for pre and post scans in vehicle servicing, especially within body shops. These scans are not just about identifying existing issues; they are about ensuring comprehensive repairs and maintaining customer trust.
One incident involved a 2012 Dodge Ram that underwent a rear bumper repair at a body shop. During its time there, the vehicle’s battery was completely drained, requiring a jump start. Upon receiving the truck, the customer reported poor engine performance. An investigation revealed a completely dead battery again. While aftermarket wiring suggested a potential parasitic drain, a closer look exposed a new alternator – a clear indicator of pre-existing electrical problems. It’s plausible the customer was unaware of these issues prior to the body work, or simply overlooked the connection. A pre-scan in this scenario would have immediately highlighted the low voltage codes and potential PCM issues, setting clear expectations and guiding necessary repairs beyond the bumper.
The second case revolved around a request to “program” the airbag system of a Nissan Sentra. Intrigued by the unusual nature of a Nissan airbag programming call, a preliminary scan was conducted. The scan revealed B1431-13 codes, indicating a pre-tensioner circuit open on both instances. Physical inspection of the passenger seatbelt revealed an unusually stiff tension, confirming deployment despite the collision being on the driver’s side and the absence of a passenger. The body shop technicians had apparently missed this crucial detail. A pre-scan here would have immediately flagged the deployed passenger pre-tensioner, ensuring a complete and accurate repair scope from the outset.
In both situations, the implementation of a pre-scan before commencing any repairs could have been instrumental in preventing delays and customer dissatisfaction. In the Dodge Ram case, numerous low voltage codes were present, potentially stemming from the battery drain or even pre-existing conditions. Body codes related to rearview mirrors were also detected. For the Nissan Sentra, a pre-scan would have instantly revealed the deployed passenger pre-tensioner.
Currently, among the body shops collaborated with, only a single one consistently performs pre and post scans. While discussions about the benefits of these scans have been initiated with others, there’s a perceived notion that it’s merely an avenue for increased revenue. However, the reality is that pre and post scans serve as an invaluable “CYA” (Cover Your Assets) policy. They provide a documented baseline of the vehicle’s condition before and after repairs, protecting both the repair facility and the customer. Embracing pre and post scans is not just about advanced diagnostics; it’s about fostering transparency, ensuring comprehensive repairs, and ultimately, elevating customer confidence and satisfaction in the automotive repair process.
