SAS reset options


Currently, millions of vehicles on the road require reset of SAS along with other related sensors during alignment service. As this number increases, the likelihood of a shop of being asked to align one of these vehicles (that is, if they have not unknowingly done so already) is growing. Rather than turning work away, subletting to another shop, or risking a comeback, most service providers are equipping themselves to take advantage of this new opportunity.

OEMs use proprietary scan tools, capable of performing many other functions, to reset SAS and other related sensors. However, an aftermarket shop would need to purchase tools from each manufacturer and update the tools each year, which would be cost-prohibitive.

While no single aftermarket diagnostic scan tool currently resolves all SAS reset requirements, some handle at least part of the vehicles requiring reset. Even these tools, since they are intended to perform many other functions, are not geared toward a simple alignment bay solution.


Consider the following

• Diagnostic scan tools work independently from the alignment system, so the technician has no way of knowing if a vehicle requires a reset without referring to OEM service documents.

• No documentation is provided to the vehicle owner to prove the reset was completed properly.

• Both OEM and aftermarket scan tools require costly software upgrades. The high price of the tools and continuous software updates can equal thousands of dollars.

• Complexity. These tools are designed for underhood diagnostics. Using them to reset SAS and other related sensors may prove to be a complicated process, especially for an alignment technician who may not be familiar with a particular tool's operation.

• Neither OEM nor aftermarket scan tools include alignment-specific reset instructions, requiring extra training for an alignment technician and added cost.

• Since a reset must be performed with the alignment, a multi-function diagnostic scan tool may not always be available for the alignment bay, causing loss of revenues.


Using diagnostic scan tools to reset SAS requires a large investment of time and money to properly perform alignments.

Though OEM and aftermarket scan tools are possible solutions to solving these problems, it is easy to see why a shop may think the costs and complexity of these tools outweigh the benefits.
