LDW calibration scenerio with no Alignment

Patrick Business Development Manager Oakbank, Manitoba Posted   Latest  

This might have been discussed before and if it has please ignore this.

A customer has an ADAS equipped vehicle and has a cracked windshield and gets it replaced at a glass shop. 

Unknown to the technician the car needs an alignment and has not been completed prior to the glass installation. In addition, it has a steering angle sensor and this also not been calibrated. The glass shop calibrates the LDW portion and takes for a test drive and cannot seem to be able to resolve the issue. The glass shop takes it to a shop for an alignment check and discovers the issue and completes both the Alignment and Steering Angle Sensor reset procedures. The car is then re-calibrated for the replacement issue and this resolves the issues.

To my knowledge, the OE does not have a position statement that states that an Alignment must be checked/performed prior to an ADAS calibration. How is everyone handling this if know one is paying for the alignment (Insurance Company) or glass shop.

Actually, Kia does indeed state that alignment should be confirmed to be within specs before doing any ADAS calibrations. I'm sure most other car makers state the same.

Thanks Ty, can you direct me to it? Was looking at oem1stop​.​com/position-state… however couldn't locate.

Not that I am trying to get you to do so, but if you bought a temporary subscription to Kia service info, it's stated all over the place. Think about it. Those systems are calibrated based on the centerline of the vehicle. If an alignment issue changes that center line, it may not work properly. There is a window for error I'm sure. It's usually recommended to do a "zero" reset of the SAS

Patrick, You state a valid issue in the industry. There are many glass companies which perform the ADAS calibration. The question to be are they capable of the calibration. In most cases YES! The issue is diagnosing the vehicle if it has issues. At this point it should be left up to the trained professional the automotive technician. There are way to many variables involved when dealing with…

I have reviewed the Job Aid, thank you for this. It appears that they recommend that the LDW/FCW be aimed after a wheel alignment has been completed. Everyone has there angle on attempting to justify their position. From mine it is to ensure that Alignments are completed, SAS are reset in prep for the calibration. The video from CarQuest makes sense as if the car's thrust is off as well as SAS…

Randy did a good job of explaining and that was a good video. One thing to add, you can bypass the instructions on making the geometry arcs. There is a tech tip on TIS to input the calculations to get the correct distance from the front bumper to the target. Make sure you’re always checking the memory inputs on SI as from the factory it comes with different inputs. Toyota states that you…

Agreed most OE will specify alignment, somewhere usually near top of calibration instructions. But other times you do need to hunt. Same issue with ACC on a Honda.

Hi Patrick: OEMs revise their position statements based upon various criteria. One of which may be the job not being performed in a manner that they want it to be. My point is don't sandbag old data. Haunt around this site for a while and see if it helps. There is some free access but you have to look for it. rts​.​i-car​.​com/collision-repa… HTH, Guido

Kia says they "recommend" to check vehicle toe-in. Honda I am not seeing to check alignment. I would say it varies on different vehicles. Steering angles sensors and Yaw rate sensors are in all vehicles now a days. Anytime toe is adjusted, Hunter wants you to perform a steering angle sensor adjustment. To be honest what im seeing its the wild wild west when it comes to ADAS calibrations…

Hi Jacob: This appears to agree with your take in regards to Honda though not AllData's. Granted, it is almost a year old and a newer version should be looked for. Please not how many revisions have been made so far. That's only been in a couple of years. (I-CAR has a bulletin addressing why this is or I should say, could…

Hello Guido, thank you for the reply back and the links will be helpful. I’ve seen that job Aid before. I will look forward to a revised version. I don’t think you were calling me out or standing on my shoulders at all. Although you have deemed yourself as the name Guido. Lol. Thank you for your insight and hopefully we will have more information in the coming years and hopefully all these…

So some interesting findings in this for the scenario where there is a glass claim. My next scenario would be if there is no claim, however based on the OE anytime there is an Alignment severely out of spec it requires a camera and/or radar calibration. This in my opinion would be the customers responsibility to pay. What if they decide, no just perform the alignment, don't worry about the…

Hi Patrick: I'd be a liar if I tried to say that I am as well versed in the regulations of your province, let alone your country as I am with my own. I will go out on a limb and say that the safest course of action will be to follow OEM guidelines & procedures, along with keeping a copy of what you did and why. Once upon a time, I used to tell people that they could safely delete old…

This is always an interesting topic. As cut and dry as it should be, it really isn't. SI verbiage such as "if you suspect the alignment is off, if must be checked" or "a collision no matter how minor..." do not really help the service industry at all. I am a "pro-alignment" guy - I have scoured SI looking for "ins" and not "outs" when it comes to wheel alignments prior to forward-facing ADAS…
