PROGRAMMING ORDER ASSOCIATED MODULE MISC. FUNCTION
1 RF-Hub replacement Perform the Vehicle Restore Configuration Enable KEYs/FOBIKs (Only the new FOBIK needs to be present, previously stored FOBIKs will remain enabled.) Perform the Vehicle Restore Configuration Flash the ECM/PCM if the Spare Part is supplied without software Transfer secret key to ESL / ECM RF-Hub replacement Perform the Vehicle Restore Configuration RF-Hub replacement RF-Hub replacement Perform the Vehicle Restore Configuration Perform the Vehicle Restore Configuration Flash the ECM/PCM if the Spare Part is supplied without software Perform the Vehicle Restore Configuration
2 Disable KEYs/FOBIKs (Only if the procedure did not run automatically after the RF-Hub replacement procedure. All FOBIKs should be present, but the FOBIKs not present at this time will be temporarily disabled. It will be possible to re-enable them by running the Enable KEYs/FOBIKs procedure.) RF-Hub replacement ---- BCM replacement Control unit replacement (If available will be found in the ECM ECU.) PROXI alignment procedure Disable KEYs/FOBIKs ONLY using the already stored FOBIKs (Only if the procedure do not run automatically after the RF-Hub replacement procedure. The FOBIKs not present at this time will be temporarily disabled but will be possible to re-enable them running the Enable KEYs/FOBIKs procedure) BCM replacement (first phase, at a certain point will be asked to configure the RF-Hub, at that point run the RF-Hub replacement, after the RF-Hub replacement and the Disable Fobiks procedures run again the BCM replacemnt procedure in order to complete the BCM configuration) Disable KEYs/FOBIKs (Only if the procedure do not run automatically after the RF-Hub replacement procedure. The FOBIKs not present at this time will be temporarily disabled but will be possible to re-enable them running the Enable KEYs/FOBIKs procedure) Disable KEYs/FOBIKs (Only if the procedure do not run automatically after the RF-Hub replacement procedure. The FOBIKs not present at this time will be temporarily disabled but will be possible to re-enable them running the Enable KEYs/FOBIKs procedure) BCM replacement BCM replacement Control unit replacement (If available will be found in the ECM ECU.) RF-Hub replacement
3 RF-Hub_TPM Update FF_FR Axle Nom Tire Press Val (only if the vehicle is equipped with TPM sensors, or if the current pressure value set by the RF-Hub replacement routine is different from the expected due to aftermarket tire size on the vehicle.) Disable KEYs/FOBIKs ONLY using the already stored FOBIKs (Only if the procedure do not run automatically after the RF-Hub replacement procedure. The FOBIKs not present at this time will be temporarily disabled but will be possible to re-enable them running the Enable KEYs/FOBIKs procedure) ---- Run BCM ECU Reset (Found under the Diagnostic Procedures Tab of the Vehicle View screen) Transfer secret key to ESL / ECM (only if the Control unit replacement procedure was not available in previous step.) ---- Enable KEYs/FOBIKs ONLY using the new FOBIK(s) and eventually FOBIKs not presented during the Disable KEYs/FOBIKs procedure (Only the new or previously disabled FOBIK needs to be present, previously stored FOBIKs will remain enabled.)
