While Bosch no longer produces OBD2 scanners, their legacy devices remain popular for their diagnostic and code reset capabilities. This guide explores how Bosch OBD2 scanners, like the OBD 1350, can be utilized for effective code resetting and vehicle diagnostics.
Understanding Bosch OBD2 Scanners and Code Reset
Bosch OBD2 scanners were renowned for their comprehensive functionality, including reading and clearing diagnostic trouble codes (DTCs) across a wide range of vehicle makes and models. The code reset function allows users to clear the check engine light and address underlying vehicle issues after repairs are made.
Vehicle Coverage and System Diagnostics
Bosch scanners offered extensive vehicle coverage, supporting most domestic, Asian, and European vehicles from 1996 and newer (OBD II & CAN compliant), including models from GM, Ford, Chrysler, Toyota, Honda, Nissan, Hyundai, BMW, Mercedes, and more. Beyond basic powertrain codes, these tools could access and diagnose issues within ABS, SRS (airbag), and other critical systems.
CodeConnect and Enhanced Datastream
Bosch scanners often featured CodeConnect, a vast database providing likely causes for specific DTCs, aiding in efficient troubleshooting. Enhanced datastream capabilities offered real-time insights into various vehicle parameters, including transmission data for GM and Ford, fuel mileage monitoring (MPG, average MPG, etc.), and battery, alternator, and charging system monitoring.
Additional Features and Functionality
Several Bosch models provided features like AutoID for automatic vehicle data population, oil light and battery life resets, access to all OBD II global data modes (including Mode 6 and O2 monitor tests), data graphing, and multilingual menus. The OBD 1350, for example, could read, record, and playback live sensor data, assisting in in-depth analysis.
Performing a Code Reset with a Bosch OBD2 Scanner
While the specific steps may vary slightly depending on the Bosch scanner model, the general process for resetting codes typically involved:
- Connecting the Scanner: Plug the scanner into the vehicle’s OBD II port, usually located under the dashboard on the driver’s side.
- Turning on the Ignition: Turn the ignition key to the “on” position without starting the engine. This powers up the scanner and allows it to communicate with the vehicle’s computer.
- Accessing the Diagnostic Menu: Navigate through the scanner’s menu to find the “Read Codes” or “Diagnostics” option.
- Reading and Identifying Codes: The scanner will retrieve any stored DTCs. Note down the codes for further research using resources like CodeConnect or online databases.
- Clearing the Codes: After diagnosing and addressing the underlying issue, locate the “Clear Codes” or “Erase Codes” option in the scanner’s menu. Confirm the action to clear the DTCs and reset the check engine light.
Conclusion
Although Bosch OBD2 scanners are no longer available new, their capabilities for code resetting and diagnostics remain valuable for vehicle owners and technicians. Understanding the features and functionality of these tools, alongside the proper procedure for code resetting, enables effective vehicle maintenance and troubleshooting. Remember, clearing codes only addresses the symptom (the check engine light); always diagnose and repair the underlying problem to prevent recurring issues.
