When the CAN bus malfunctions or data transmission is abnormal, various strange fault phenomena often occur, such as abnormal dashboard displays, inability to start the vehicle, failure to turn off after starting, decreased vehicle performance, and loss of certain electronic control system functions. This is because relevant data or information is transmitted through the CAN … Read more
4. Short Circuit of CAN L to Ground When a short circuit occurs between CAN L and ground, due to the fault tolerance characteristics of the CAN bus, the entire CAN network may be unable to communicate or generate related fault codes. However, for certain vehicle models, such as Haima, the fault tolerance characteristics of … Read more
5. Short Circuit of CAN L to Power (Positive) When a short circuit occurs between CAN L and the power (positive), due to the fault tolerance characteristics of the CAN bus, the entire CAN network may be unable to communicate or generate related fault codes. Because of the short circuit of CAN L to the … Read more
Abstract: In order to solve the difficulty of feature extraction in analog circuits fault diagnosis and to accurately classify fault pattern, a new analog circuit diagnosis method based on the combination of optimal wavelet basis, fuzzy theory and self-organizing feature map is proposed. The response signals of the analog circuit are preprocessed by wavelet transform … Read more
