OP-COM V1.99 for Opel/Vauxhall – FT232RQ + PIC18F458 OBD2 Diagnostic Interface with CAN-BUS Support
Felkodsläsare
The OP-COM V1.99 is a PC-based OBD2 diagnostic interface for Opel and Vauxhall, developed for those who want to do more than just generic engine diagnostics. With support for many Opel-specific control units, the tool can be used to read and clear fault codes, view live data, read measuring blocks, and perform output tests on compatible systems.
```This version is stated to have firmware V1.99, software 2014V/120309a, FT232RQ driver IC and PIC18F458 chip according to the main specification. The product text describes support for many Opel models, including newer vehicles with CAN-BUS-based diagnostics, such as Vectra-C, Astra-H and Zafira-B.
OP-COM is particularly useful as Opel uses several different communication pathways in the OBD connector. The interface therefore acts as a multiplexer and selects the correct pin for communication, for example, serial link via PIN3/PIN7/PIN8/PIN12 as well as HSCAN, MSCAN and SWCAN for CAN-BUS systems.
Important: The product information clearly states “Never Update Online”. Therefore, do not update the interface online if your delivery has this warning, as incorrect updates can damage the OP-COM interface or render it unusable.
OP-COM is a specialized diagnostic interface for Opel/Vauxhall used in conjunction with a Windows computer. It is not just a simple OBD2 reader for the engine light, but an Opel-specific tool that can communicate with several different control units in the car, depending on the model, year, equipment level and software support.
```The interface connects to the car's 16-pin OBD2 socket and to the computer via USB. The OP-COM software is then used to select the car model and control unit, read fault codes, view measurements and, in some cases, perform activation tests.
The version in this product description is stated as Firmware V1.99 and Software 2014V/120309a. It is also referred to as OPCOM 2014V diagnostic tool for Opel cars.
```According to the product information, OP-COM V1.99 can be used for several important diagnostic functions:
```Some advanced functions require additional knowledge, the correct car model, and the correct security code/Car-Pass where relevant.
```The product text mentions support for many control units. Exact support varies between car models and model years. Examples of systems mentioned:
```For simpler troubleshooting, you normally start with engine control, but the strength of OP-COM is that the tool can often access more systems than a regular generic OBD2 reader.
```OP-COM can display fault codes with more information than a simple code list. The product text mentions, among other things, full status information:
```This is important for troubleshooting because an intermittent fault often requires a different troubleshooting method than a permanently active fault. From the fault code window, you can, according to the product text, proceed to measuring blocks to check relevant live data.
```The program displays measured values from many control units. You can select parameters from the list and monitor several values simultaneously. According to the product information, the program can display 8 measuring block parameters simultaneously.
```The sampling rate depends on the car's communication system. Older ISO/KWP systems can be slow, while newer CAN-based systems normally provide much faster updates.
```According to the product information, OP-COM can perform output tests on many controllers. Output tests are used to activate a component or function via the control unit, for example, to see if a fan, valve, lamp, relay or other controlled component responds.
```This is a very useful function for troubleshooting, but it should be used with caution. Never activate a test if you don't know what the component does or if the car is not securely positioned.
Safety: Output tests can start fans, pumps or other components. Keep hands, tools and cables away from moving parts.
```Opel uses several different communication pins in the OBD connector. The OP-COM interface therefore acts as a multiplexer and selects the correct pin for communication with the respective system.
```This multiplexer function is a major reason why OP-COM can be more useful on Opel than a simple ELM327-based OBD2 reader.
```Software is not included.
Code 28 normally means that the driver is not installed. Solution:
The product information clearly states: “Never Update Online. Online Updation Will Damage The OP-COM.”
```This means that you should not attempt to update the interface online if your delivery has this warning. Incorrect updates can cause the interface to stop working.
According to the product text, OP-COM 2014V covers almost all Opel models, including newer models with CAN-BUS-based diagnostics. Examples mentioned include:
```Exact support always depends on the car model, model year, ECU version, installed equipment, and the software's database. A function available on one model does not necessarily work on another.

The main specification states PIC18F458 and driver IC FT232RQ.
Yes, it can read and clear fault codes on supported Opel control units.
Yes, the program can display measuring blocks/live data and up to 8 parameters simultaneously where the system supports this.
Yes, the product information states support for CAN-BUS-based diagnostics, including HSCAN, MSCAN and SWCAN.
Yes, these models are mentioned as examples in the product information.
No, not if your delivery states “Never Update Online”. The product text warns that online updating can damage the OP-COM.
No, the interface is USB-based. The product text states that this avoids compatibility issues with serial-to-USB converters.

The product's FAQ mentions reset/programming of the service interval reminder for, among others, Astra-G, Zafira, Corsa-C and Meriva.
The product text mentions immobilizer- and key-related functions. Such functions should only be used legally, on your own vehicles or with explicit permission, and may require the vehicle's security code/Car-Pass. We do not recommend that inexperienced users work with anti-theft systems.
They show the status of the fault code: active fault, stored but not active fault, or a fault that comes and goes.
OP-COM is Opel-adapted and can communicate via several Opel-specific pins and CAN lines, which provides support for more systems than generic OBD2.
For simple fault code reading, it can be used by experienced home mechanics, but advanced functions such as output tests, coding and security-related functions require knowledge.
