For a short time, in the 90’s when vehicles with electronic controls where common the common place was for engine to be controlled with electronics for driving injectors etc. That was so in the 90’s today vehicle utilise multiple networks across multiple computers to share information and carry out adjustments and safety judgements based on real time driving events. you do really have to work on all makes and models to have such a broad view on how this all works, but luckily you have come to the right place.
We use many different types of tools to diagnose a vehicle, We use Hanatec, Heshbon, Carman scan, Bosch diagnostics, Launch and autel including many genuine softwares and hardware to accommodate the vast variety of vehicles in the market place today.
all of the scanners and diagnostics equipment have there good and bad points and no one tool is perfect thats is exactly the reason we have so many scan tools, to be able to diagnose any vehicle that comes in the shop.
Various tools are available that plug in to the OBD connector to access OBD functions. These range from simple generic consumer level tools to highly sophisticated OEM dealership tools.
Hand-held scan tools
A wide range of rugged hand-held scan tools are available.
- Simple fault code readers/reset tools are mostly aimed at the consumer level. They may read simple error codes, possibly without translating the meaning, and reset those error codes.
- Professional hand-held scan tools may possess more advanced functions
- Access more advanced diagnostics
- Set manufacturer- or vehicle-specific ECU parameters
- Access and control other control units, such as air bag or ABS
- Real-time monitoring or graphing of engine parameters to facilitate diagnosis or tuning
PC-based scan tools and analysis platforms
A PC-based OBD analysis tool that converts the OBD-II signals to serial data (USB or serial port) standard to PCs or Macs. The software then decodes the received data to a visual display.
In addition to the functions of a hand-held scan tool, the PC-based tools general offer:
- Large storage capacity for data logging and other functions
- Higher resolution screen than handheld tools
- The ability to utilize multiple software programs adding flexibility
The extent that a PC tool may access manufacturer or vehicle-specific ECU diagnostics varies between software products as it does between hand-held scanners.
Data loggers are designed to capture vehicle data while the vehicle is in normal operation, for later analysis.
Data logging uses include:
- Engine and vehicle monitoring under normal operation, for the purpose of diagnosis or tuning.
- Monitoring of driver behaviour by fleet vehicle operators.
Analysis of vehicle black box data may be performed on a periodic basis, automatically transmitted through wireless to a third party or retrieved for forensic analysis after an event such as an accident, traffic infringement or mechanical fault.
OBD-II testing instead of tailpipe testing in OBD-II compliant vehicles (1996 and newer). Since OBD-II stores trouble codes for emissions equipment, the testing computer can query the vehicle’s onboard computer and verify there are no emission related trouble codes and that the vehicle is in compliance with emission standards for the model year it was manufactured.
