Parking sensor calibration for Seattle and Tacoma Body Shops
Parking sensor calibration reseats and recalibrates the ultrasonic sensors in the front and rear bumper covers so distance warnings fire at the correct range. The OEM requires it after any bumper R&I, sensor replacement or Park Assist module swap. Focal ADAS performs it on-site in 30 to 90 minutes with full pre and post-scan documentation.

When this calibration is required
Triggers below come from the manufacturer's published procedure for the build. Any one of them is enough to put the line on the file.
- Front or rear bumper cover R&I or replacement
- Any ultrasonic sensor replaced or rotated in its grommet
- Park Assist module replacement or software update
- Refinish work on the bumper cover that changes sensor seating
- Stored DTC on the Park Assist or ultrasonic module
How Focal ADAS performs it
- 1Pre-scan and VIN decode
We pull every stored DTC and decode the VIN to load the exact OEM calibration procedure for that build.
- 2Target setup or drive prep
Targets are placed at OEM-specified distances and angles in your bay, or the dynamic drive route is staged.
- 3Calibration procedure
Static, dynamic, or both — performed in the order the manufacturer requires, with the scan tool driving the sequence.
- 4Post-scan and verification
A clean post-scan confirms the calibration completed and no new faults were set during the procedure.
- 5Documentation handed off
Pre-scan, post-scan, completion record, OEM procedure reference, and setup photos delivered with the invoice.
What the shop gets
- Pre-repair scan report (all modules)
- Post-repair scan report (all modules)
- OEM calibration procedure reference (build-specific)
- Calibration completion record from the scan tool
- Setup photos of targets / drive evidence
- Itemized invoice — pass-through ready
Single-system calibrations start at $349, multi-system jobs quoted by VIN.
Frequently asked questions
Don't the sensors self-calibrate?+
Only the audio cadence. The distance reference is set at the factory and the OEM procedure expects a service-tool calibration after any disturbance, even if no fault is stored.
What if one sensor reads differently from the others?+
That's usually a seating depth or paint-thickness issue at the grommet. We catch it at setup and reseat before calibrating the array.
Can this be combined with a radar calibration?+
Yes — most bumper jobs need both. We do them on the same trip and document them as separate line items.
