Modern vehicles rely on interconnected networks to operate electronic systems efficiently. While high-speed Controller Area Network (CAN) handles critical engine, transmission, and drivetrain communications, low-speed networks such as Local Interconnect Network (LIN), J1850, and K-Line manage smaller body-related systems and diagnostic access. Understanding how these networks operate, their voltages, and signaling patterns is essential for accurate troubleshooting and repair.
In this Technical Focus Article, learn about the main components of Variable Valve Timing, the functions & benefits, VVT history, and common causes of VVT malfunction. We include a case study on a 2004 Honda Accord® EX 2.4L as well!
In this Technical Focus Article, you'll learn how using a lab scope alongside a scanner gives techs deeper, real-time insight for more accurate diagnostics that reveal intermittent faults hidden in OEM-specific systems.
In this Technical Focus Article, learn about how U-codes identify communication faults between vehicle control modules, typically caused by wiring, DLC pin, or scan tool adapter issues. Proper diagnosis is key to resolving U-code errors and ensuring accurate automotive communication system repairs.
