ADAS & Alignment

Pam Owner/Technician Florida Posted   Latest   Edited  

In a T3, right now. Have a split decision on align before ADAS recalibration versus no alignment before ADAS recalibration. The ”no alignment“ bases their stance on “since no manufacture requires it.”

(I say do it right or go home.)

Any pro/con thoughts out there?

If the Thrust angle of the vehicle is not correct, no static ADAS calibration would be accurate. A dynamic system may be able to correct for it.

Pam..I agree with you. Do it right or not at all. Is it a cost issue why an alignment is not being done first?

Does it depend on what information source is used? If a source like alldata is used, look at the labour guide for front camera calibration or front radar calibration. There you can find evidence of alignment “inspection” as a requirement. One may then assume if the alignment is not correct it would require an alignment before calibration… what are your thoughts on that?

From All Data for Honda CRV Calibration Calibrate Cruise Control Sensor, Calibrate B 0.0 1.5 Includes wheel alignment check and post road test. Does not include diagnostics, wheel alignment adjust, or bumper removal.

Any calibration that bases target position on the centerline of the body must have correct thrust angle, end of story. Whether the OE specifically calls it out or assumes that it's being done based on the understanding of system operation it still needs to be done. Not every OE will specifically tell you not to drink the battery fluid ;)

Randy, What are your thoughts on Toyota wheel alignments pre- forward facing ADAS calibrations? Allegedly they calculate the beam axis differently, and are not based off of the thrust angle? I have had 2 Toyota's that absolutely needed a wheel alignment prior to forward radar calibration or they would fail the calibration. The first one to figure out was a major PIA. Also, some of the…

All good points Bob. The OEs just can't seem to land on a definitive recommendation. Possibly the anticipated warranty labor costs factor into that. But we do know one thing for a fact. If targets are positioned according to the centerline of the body then thrust angle has to be spot on. There is just no getting around that, verbiage or no. As to the insurance industry their goal is to minimize…

Regardless all Adas calibrations assume correct alignment, most suggest alignment prior to (regardless of what all data says). (Also steering angle must be set in correct position)

I attached Honda ADAS Calibration requirements, GM, and Nissan. Global appears to be the direction they are going.

Base on your question ,Pam . Beside of Doing alignment or not ,according to manufacture service manual ,I have learn to trust my instincts also. i do this procedures on any vehicle I deal with ADAS calibrations (static or dynamic ). for me in particular I deal with a collision repair industry all the time . i follow the manufacture requirements,but I have find out that your instinct don’t…

This seems to be the flip question to whether an ADAS target based calibration(regardless of complexity) is required after a non accident related alignment is performed. The answer to your question seems to come down to a similar challenge. “Are the folks doing the recalibration equipped to perform an accurate alignment, in the same facility, or at the same time as when performing the…

Your right in a way Randall Since Collision Repairs Facilities received crash vehicles every day and not coming for a regular service check. Alignment checks should be done in House and performed always . after the final repairs are done a preliminary test will be performed ,a test drive and checks for calibrations must be then carry out . last It will be your final scan report . the…

Thanks for the clarification. I did mis-interpret the question. Not many Tesla's in my neighborhood
