As-Built
BCM 726-45-01: xxxx **** xxxx (hex tire circumference in mm)
As published by the source below. Compare against your own backup; surrounding digits control other features.

Notes

Wrong values skew speedometer, odometer and speed-dependent systems. The spreadsheet links a circumference calculator.

How to apply it

  1. Back up every module's As-Built data and keep the files somewhere safe.
  2. Connect FORScan with a battery maintainer on, ignition ON and engine OFF.
  3. Open Configuration and Programming, choose the BCM module, open As-Built Format and edit only the digit described by the source.
  4. Write, follow any module reset prompt, cycle the ignition, then confirm the feature and check for new trouble codes.
