In cases where no error code is present in the vehicle, specialists typically initiate their work by inspecting circuits or connecting an OBD2 scanner to analyze the technical parameters of the electrical components. If necessary, they’ll conduct tests on system elements, and MotorData can be a valuable aid in this process. For instance, it can provide component locations on the electrical circuit.

MotorData Professional boasts an extensive collection of over 20,000 wiring diagrams that cover a wide range of vehicles from Asia and America. The software is designed for rapid diagram searching and comparison. Each diagram is interactive, allowing users to zoom in or out as needed. Clicking on the circuit trace reveals further details. Different wire colors aid in locating faults swiftly. By clicking on components or wires within the diagram, technicians can easily identify fuses and relays in various circuits. Furthermore, each element on the diagram is accompanied by additional information, and users can seamlessly navigate to other sections of the software.

Service Bulletins and Typical Troubleshooting (TSB)

Service Bulletins and Typical Troubleshooting (TSB)

MotorData Professional includes valuable resources such as vehicle manufacturer Service Bulletins (TSBs) and troubleshooting guides, which alert electricians to common electrical issues.

TSBs, or Technical Service Bulletins, are compiled by car manufacturers and distributed to automotive repair shops for addressing specific problems. These bulletins detail common vehicle issues, provide diagnostic procedures, repair instructions, and even list the required parts and estimated repair times. Additionally, the software offers insights into typical malfunctions and proven methods for resolving them, drawn from the experiences of seasoned auto mechanics.

Equipped with this wealth of information, an auto electrician can often quickly identify and address specific malfunctions.

MotorData proves invaluable by offering location diagrams for ECUs, sensors, relays, mounting blocks, ground points, and intermediate connectors on the vehicle’s body. Finding the necessary element is straightforward, with quick transitions to the relevant location on the electrical circuit or wiring block diagram.



For detailed element testing, including sensors, switches, relays, and actuators, MotorData provides comprehensive step-by-step instructions. The software covers procedures for reading fault codes, initialization, as well as general checks and adjustment processes.

Real-Life Success Stories

Here are a couple of real-world scenarios demonstrating the effectiveness of MotorData Professional:

A Toyota Ipsum 2009 with error code P1315 arrived at the service station. Using MotorData, the auto electrician quickly decoded the issue and received repair recommendations related to the Powertrain control unit, ignition coil, wiring, and connectors. The ignition coil was promptly replaced, resulting in a satisfied and swiftly departing customer.

A Mitsubishi Outlander 2016, 2.0 L MIVEС, was brought to the service center due to a malfunctioning heater. The MotorData interface allowed the auto technician to identify the air conditioning control unit in the diagram, as well as pinpoint A257 – a regulator, relay, and fuse. Locating these components in the vehicle for inspection was effortless, thanks to the program’s clear depiction of their positions on the electrical circuit and in the mounting block. Furthermore, MotorData provided the actual location of the mounting block beneath the dashboard. Diagnostic measurements confirmed a faulty fan motor, which was promptly replaced.

In conclusion, MotorData Professional is an invaluable tool for auto electricians, significantly improving efficiency in their daily work. It expedites troubleshooting and repairs, ultimately boosting the profitability of the car service by allowing more tasks to be completed in a single day.
