Tire Size Calibration |
| This function is used to view the existing tire calibration or to program tire size information into the EBCM memory. This must be done when a new EBCM is installed in the vehicle or when different size wheel/tires are installed on the vehicle. Important: The VCM/PCM must also be programmed with the correct tire size calibration when wheel/tire size is changed. When calibrating the modules the EBCM must match the front tire size and the PCM/VCM must match the rear tire size | ||||
Function Test | -- | The Function test commands the system internal relay, valve solenoids and the pump motor on and off in order to verify proper component operation. If a malfunction is detected the EBCM will set a DTC(s). |
