IMPORTANT:
The PCM must also be programmed with the correct tire size calibration when different size tires are installed on the vehicle. Refer to Service Programming System (SPS)
in Programming. This function allows the technician to read the tire size calibration of the EBCM or calibrate the EBCM to the correct tire size. Calibration must be performed when the EBCM is replaced or when different size tires are installed on the vehicle. |
