Modern Auxiliary Systems Trainer
by LJ Create
Electric windows, door mirrors, power seats, and central locking are among the most frequently complained-about systems in automotive service, and they are increasingly governed by CAN bus communication rather than simple switched circuits. A window that will not operate from the passenger door switch but works from the driver master switch is not a broken window motor. It is a CAN communication fault, a faulty switch module, or a body control module issue that requires a completely different diagnostic approach than the circuit-by-circuit checks that worked on older vehicles.
The LJ Create Modern Auxiliary Systems Trainer gives students the hands-on investigation experience they need to develop that diagnostic approach, covering CAN Bus electric window, door mirror, seat, and central locking circuits in a practical, task-based format that builds real diagnostic competency for the auxiliary system faults that fill automotive service bays every day.
Klein Educational supplies LJ Create automotive training systems to automotive technology programs, community colleges, CTE programs, and workforce development centers across California, Oregon, Washington, Arizona, Nevada, Hawaii, and Alaska.
What is the Modern Auxiliary Systems Trainer?
The Modern Auxiliary Systems Trainer is a desktop-format autotronics trainer focused on the CAN bus-controlled auxiliary systems found throughout modern vehicle interiors. The trainer sets students practical tasks that encourage them to explore CAN Bus electric window, door mirror, seat, and central locking circuits, improving their knowledge of these systems through active circuit investigation rather than passive observation.
Students investigate how the body control module and CAN communication govern each auxiliary system, how individual switch inputs are processed and transmitted over the network, how fault codes are generated when system faults occur, and how to use live data and fault code information to identify the root cause of auxiliary system complaints. The fault-finding activities in the trainer directly prepare students for the diagnostic scenarios they will encounter most frequently in general automotive service.
What students learn
The trainer supports instruction in CAN Bus auxiliary system architecture and body control module operation, electric window circuit construction and CAN communication, door mirror adjustment circuit operation and network integration, power seat circuit construction and control, central locking circuit operation including both lock and unlock pathways, CAN data monitoring for auxiliary system signal verification, fault code generation and interpretation for auxiliary system faults, and systematic fault-finding in CAN-controlled auxiliary systems.
