- 35CAN Bus fundamentals — make the network visibleSeveral unrelated modules show ‘no communication’ after one wiring fault. Before replacing modules, understand what the two twisted wires are actually doing.Members only35 min
- 36CAN Bus fault diagnosis — opens, shorts and a node pulling the bus downThe whole bus goes quiet when one module is connected. How do you prove whether the wiring, termination or one ECU is collapsing the network?Members only35 min
- 37LIN Bus — the single-wire network on smart componentsA blower controller, smart alternator, mirror or wiper has power and ground but ignores commands. The missing piece may be one LIN wire.Members only35 min
- 38FlexRay — understanding high-speed deterministic chassis networksA premium vehicle has communication faults in chassis/safety systems, but the network is not conventional CAN. What changes when the architecture uses FlexRay?Members only35 min
- 39MOST Bus — fibre-optic infotainment ring diagnosisRadio, amplifier, navigation and display all disappear together after one infotainment module fails. Why can a single module break an entire optical ring?Members only35 min
- 40Automotive Ethernet & DoIP — modern ADAS and gateway networksCamera/radar/central gateway modules communicate at far higher data rates than classic CAN. How do you recognise Automotive Ethernet and avoid diagnosing it like a normal CAN pair?Members only35 min
