Abstract
A method for recovering control of a continually resetting control module is provided. The method recovers control by monitoring a vehicle's communication links for a very short period each time the boot program starts and before control is passed to the application program. Alternatively, control may also be recovered using a running reset counter (RSC) that increments every time the boot program is entered via an abnormal condition. After recovering control, the control module can communicate with an external tool to diagnose and/or reprogram the control module and thereby prevent continual reset.
