Who is right when stating that centering gauges establish vehicle datum?

Centering gauges are tools used in the collision repair process to establish a vehicle's datum, which is a predetermined reference point from which measurements can be taken. This is crucial in ensuring that the vehicle's frame and structural components are aligned correctly after an accident. By using centering gauges, technicians can accurately assess and restore the vehicle's original factory specifications, helping to ensure safety and performance.

If both technicians in the question are acknowledging the role of centering gauges in establishing the datum, then their statements collectively support the idea that these tools are indeed integral for accurate measurement and alignment in vehicle repairs. This is why affirming that both technicians are correct makes sense within the context of proper automotive appraisal and repair practices. The ability to correctly use and interpret the outcome of these measurements is essential for any physical damage appraiser, highlighting the importance of understanding the function of centering gauges in the repair process.
