The OP-COM cable version 1.67 is designed for comprehensive diagnostics and coding of Opel, Vauxhall, Holden, Chevrolet vehicles from 1987 to 2016 model years. This professional tool connects via USB Type-A (standard computer USB port) to a laptop or PC running Windows XP, 7, 8, 10 and 11 with nuances operating systems.
With the OP-COM cable and corresponding software, you gain access to full dealership-level diagnostics. The system not only reads and decodes fault codes in English but also allows you to view real-time parameters of all vehicle systems.
This OP-COM is not just a cable, but a device with its own microcontroller and internal firmware. This firmware version (from 1.39 to 1.67) must be compatible with the OP-COM software version on the computer. The ability to reflash the firmware allows for more flexible use of the cable and adapts it to different Opel models and years of production. This function is necessary if the cable does not detect a specific vehicle or some of its modules; reprogramming to the required version often solves the problem.
Main features of the OP-COM 1.67 cable:
- Complete diagnostics of all electronic systems: engine (ECM), transmission (TCM), ABS, ESP, SRS (airbags), climate control, body electronics, and more.
- Decoding and clearing fault codes with detailed descriptions of possible causes.
- Vehicle coding (programming) after installing additional equipment: fog lights, parking sensors, xenon headlights, cruise control, audio systems, etc.
- Adaptation and programming of ignition keys: adding new keys, deleting lost ones, immobilizer synchronization.
- Reading and writing ECU data, resetting service intervals, activating hidden functions.
The OP-COM cable version 1.67 is compatible with OP-COM 2016 Professional software and earlier versions. It supports multiple firmware updates (Firmware Update) in the firmware version range from 1.33 to 1.67. This feature is necessary if the cable doesn't detect a specific vehicle or some of its control units – in such cases, flashing to another version often solves the problem.
Important: We do not provide software installation or configuration. When purchasing the cable, you only receive the hardware. Brief consultation on connection is possible. Users must find and install the software themselves.
