Calibration FlashĪ calibration-flash failure is not critical and will generally not result in an unrecoverable controller. The only way to recover the controller is to disassemble it and physically remove, reprogram and replace the flash chip on the main circuit board. If flashing fails with a “no communications” error then the controller has probably been rendered inoperable and unrecoverable. If power has been removed from the controller, it may only be recoverable if the flash was at least 15%-20% complete and the communications portion of the operating system was reprogrammed to allow the controller to continue to operate in dead poll mode. Retry the full flash procedure until it is successful. As long as the controller remains powered up, EFILive’s proprietary boot loader running in the controller will continue to wait for a successful full flash procedure. DO NOT REMOVE POWER FROM THE CONTROLLER.To attempt to recover a failed flash for LB7 or LLY Full Flash Use pass-thru reading/flashing rather than standalone reading/flashing. ![]() If flashing in high speed revert to low speed flashing.Common communication problems are reported with the ABS, BCM, Radio, Info and Lift Pump fuses. Look up the error code number and obtain a detailed description of the cause and suggested solutions to your issue. The code displayed on FlashScan/AutoCal and in the EFILive software is an important diagnostic tool. Refer to the License Status knowledgebase article for further information. The first time FlashScan/AutoCal flashes a controller, licensing requirements are validated and must be met to facilitate a successful flash. This includes opening or closing of hood, doors, windows, as well as changing settings on radio, HVAC, connecting/removing charging devices etc. DO NOT operate any vehicle feature that may communicate on the data bus.Remove/isolate all after-market devices including mobile phone adapters, after-market equipment (audio systems, security, remote start etc) and any devices wired into the OBD port. ![]() Use a bench harness for reading/flashing (Recommended). ![]() Tips for successful reading/flashing of LB7 and LLY controllers include: In many cases, these controllers fail with factory tools and will be unrecoverable. LB7 and LLY controllers use a communications platform that is not very robust and was replaced in 2006. ![]()
