Analysis and Improvement of the Issues that RKE dose not Reliably Awake BCM

Referring to the problem that the RKE could not reliably awake the BCM for a car, extensive tests to its fault under the simulated real-vehicle installation environment are conducted. Theoretical analysis and practical tests summarize the main reasons for the unreliably to wake up from two aspects. Software programmed and a hardware programed is proposed to solve this problem. In the end, the real vehicle test provided that the optimized synchronization code can solve this problem. This paper focuses on the entire process from troubleshooting to solve problems.
