C125E-00
Fcw Warning On Instrument Cluster

We just completed engine work on this vehicle. The tech removed the front of the vehicle to gain access for the repair. After putting everything back together, the FCW light is on the dash and the adaptive cruise control is setting code C125E-00 for ACC Sensor Adjustment Required. Is there any way to perform the vertical calibration for the forward camera without using the Miller tool #10243-1? Thanks

This vehicle is calibrated by driving it with scan tool connected and vehicle in calibration mode. Prior to driving park on a level surface and confirm the sensor is perpendicular to the ground.

I believe you are referring to the ACC radar module on the vehicle, not the camera. If you didn’t touch the adjustment screws on the ACC unit, should be very close with the vertical adjustment, just run the dynamic calibration, and if it is off, the scantool will tell you witch way should be tuned on the adjustment screws.

Not sure if it is possible but I would NOT take the chance of not performing both the static and dynamic calibrations.

Just have a mobile tech come in and calibrate it for you the correct way! It is best to vertically level the radar and then do the Dynamic drive and if required make adjustments accordingly. Them old ACC radars in them vintage vehicle's take a while to calibrate.

Oscar Bonilla is correct, if you have a scan tool that can do this, when you start the calibration it will ask if you have done the static aiming, answer… yes. It will then take you to the dynamic calibration, make sure you take an adjustment tool with you and as you drive, if the module needs more adjustment made, it will stop calibrating and tell you have many turns and what direction to make…

Need the tool or sublet. This is ADAS were talking about.

That sensor is mounted on a couple of ball studs and is easily knocked off. Make sure it is not loose

The way this calibration works is the tool you specified will help you vertically level the ACC sensor. The dynamic drive cycle will calibrate the horizontal angle. You will need this tool along with level ground to properly calibrate this sensor and avoid losing during litigation if something goes wrong in the future.

Thank you for all of your replies. I called a local mobile auto tech with the proper equipment and he performed the calibration correctly. All is well, I'm happy and the customer is happy. Thanks!
