Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module Programming
Aftermarket add-ons that protrude into the Driver Assistance System Module (DASM) field of view will inhibit the ability to calibrate and will inhibit functionality. Please remove any such components prior to performing the calibration procedure.
Tool Availability:
- NA Market - The digital inclinometer is a commercially available tool. No special tool is available.
- EMEA Market - Commercially available or use special tool 2000037161.
This DASM calibration procedure is required when the:
- DASM and/or DASM and bracket have been removed.
- A NEW windshield is being installed to the vehicle.
- Tire diameter has been changed
- Calibration not learned Diagnostic Trouble Code (DTC) (C008F-00) or Sensor Adjustment Required DTC (C14A4-00) are present
If the windshield is lowered down, install the protective cover to protect the DASM. The DASM will not require programming when the windshield is raised back to its normal position as long as the DASM has not been struck or moved while the windshield was in its lowered position.
- Using a digital inclinometer, read and record the vertical angle by holding the inclinometer against the cooling ribs on the back of the DASM.
1 - DASM Adjustment Head Screw - Once the DASM angle has been determined, and if an adjustment is needed, use an e5 Torx tool to adjust the DASM adjustment head screw. Move in the appropriate direction to adjust the module, remove the torx wrench prior to rechecking the vertical alignment.NOTE:
The adjustment specification is: -1 +/- 0.2 degree from vertical. The preference is for -1 +/- 0.1 degree from vertical.
- Repeat step 1 and step 2 until the DASM is within the adjustment specification.
- After completing the vertical alignment, connect the diagnostic scan tool to the vehicle.
- Select the "DASM ECU" and then select the "Miscellaneous Functions" tab.
- Select and run the "DASM Auto Alignment" procedure and follow the on screen prompts to complete DASM calibration.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
