Electrical systems are becoming more and more important in today’s computer controlled vehicles. At A+ Japanese Auto Repair we find ourselves leading the way in the diagnosis of electrical circuits and computer controlled systems. Many local auto repair shops bring vehicles they cannot diagnosis to us for our expertise and assistance in electrical diagnosis and repair. The complexity of these systems can be visualized in wiring diagrams. Below is a wiring diagram from a 2000 Toyota Land Cruiser (Fig A.) Each line indicates a wire. In (Fig B.) Imagine then taking each straight line (wire in figure a.) and accessing testing each one individual to identify an issue and repair it. Our many years and expertise in electrical diagnosis means a cost savings to our clients as we have either seen your electrical concern before or will be able to find and repair it quickly and correctly.

Types of On Board Diagnostics:

An electrical circuit can be found in every part of a modern car. Today manufacturers are using Computer Area Network Systems or CAN systems to control vehicles. To visualize the complexity of these CAN Networks think of separate computers for your heated seats, power windows, radio, gps, transmission, computer controlled engine components etc… all connected and talking to each other. A modern car even has electrical circuits in the tires monitoring tire pressures at millisecond intervals. A+ Japanese Auto Repair Inc. requires our ASE certified auto mechanics to stay abreast with the latest electrical diagnostic methods, procedures, and repairs by constantly training and attending related classes. Our ASE Technicians are experts at electrical diagnosis on CAN (computer area network), OBDII (On Board Diagnostic 2), OBDI (On Board Diagnostic 1), Hybrid Drive Systems (HDS) and all 12 volt electrical systems. These systems are used by the following manufacturers: Honda, Acura, Toyota, Lexus,Nissan, Infiniti, Mazda, Subaru, Mitsubishi, Scion, Isuzu, Kia, Hyundai,and Hybrid Vehicles.
Below is an illustration of a vehicle using todays CAN system network (FIg C.)


Whether your system is CAN, OBDII, or OBDI the majority of these automotive electrical systems are what is referred to as a 12 volt system. In reality a healthy battery will have about 12.5 volts or more. When your vehicles engine is running the generator or alternator will increase this charge to around 14 volts. Some of the hybrid drive systems are High Volt 400V+ and high amperage which have the ability to be dangerous and or lethal. Never try to diagnose these auto electrical systems yourself as they are very dangerous. Always have an expert like A+ Japanese Auto Repair Inc. perform qualified electrical system diagnosis with Master certified ASE auto repair technicians who are experts on your Honda, Acura, Toyota, Lexus, Nissan, Infiniti, Mazda, Subaru, Mitsubishi, Kia, Scion, Hyundai, Isuzu, and Hybrid vehicles.
