Need help?

Do you have a question about the Bosch TECH 2 and is the answer not in the manual?

The Bosch Tech 2 is a diagnostic scan tool designed for General Motors (GM) vehicles, offering comprehensive diagnostic and reprogramming capabilities. It is a handheld device with a monochrome display and a keypad for navigation and data entry. The Tech 2 is equipped with a PCMCIA port for a 32 MB data card, which stores the pre-loaded software. It also features RS-485, RS-232, and VCI connectors for various cable connections.

Function Description:

The primary function of the Bosch Tech 2 is to diagnose and reprogram control modules in GM vehicles. It allows technicians to access and interpret diagnostic trouble codes (DTCs), view live data streams, perform special functions (bi-directional controls), and update software calibrations. The tool supports various vehicle systems, including Powertrain, Body, Chassis, and Service Programming.

Important Technical Specifications:

Memory: 32 MB data card (PCMCIA) for software storage.
Connectivity: RS-485 port, RS-232 port, VCI connector, and OBD II connector. For newer vehicles, it utilizes a Controller Area Network Diagnostic Interface (CANdi) module, which is an in-cable module that adds CAN capability to the Tech 2. The CANdi module supports simultaneous communications on three CAN buses and high-speed UART communications with the Tech 2.
Power: Powered by an AC power supply or through the vehicle's data link connector (DLC).
Display: Monochrome screen with adjustable brightness and contrast.

Usage Features:

Vehicle Identification: The Tech 2 allows users to select the vehicle's model year, type, make, product line, and engine type based on the VIN. This ensures accurate diagnostics for the specific vehicle.
Diagnostic Menu: Provides access to various diagnostic functions, including:
- Diagnostic Trouble Codes (DTCs): Users can scan for DTCs stored in the PCM, view specific DTCs, and access additional DTC information such as monitors that have not run since clearing codes and Freeze Frame/Failure Records. The tool can capture multiple DTCs and their associated Freeze Frames.
- Data Display: Allows viewing of individual parameter identifications (PIDs) such as EGR, EVAP, Fuel Trim, HO2S, Ignition, Misfire, TAC, and Output Driver Data. Users can scroll through multiple pages of PIDs and select specific items for focused viewing.
- Special Functions (Bi-directional Control): Enables testing of specific components by commanding them On or Off. Examples include door lock actuators, interior lamps, turn signals, and EVAP system components (purge solenoid, vent solenoid, purge/seal). This feature helps in isolating faulty components.
- Snapshot: Allows recording of data while performing tests, which is useful when holding the scan tool is inconvenient. The recorded data can be reviewed later.
- I/M System Information: Provides information related to Inspection/Maintenance readiness.
- Module ID Information: Displays calibration ID and verification numbers for vehicle modules, helping to determine if updates are needed.
- Module Setup: Offers options for specific module configurations and resets, such as Oil Life Reset and Steering Position Sensor Calibration.
Service Programming System (SPS): Facilitates "Pass Thru" reprogramming of modules. This involves connecting the Tech 2 to a PC with TIS2Web software and a clean power supply to the vehicle. The process includes selecting the diagnostic tool (Tech 2 or MDI), identifying the vehicle via VIN, selecting the controller to reprogram (e.g., PCM/VCM), and downloading the latest calibration.
Tech2 View (T2 View): Allows viewing the Tech 2 screen on a PC, which is useful for demonstration or larger display needs. This requires connecting the Tech 2 to a PC and logging into the TIS2Web website.
Getting Started: Includes example data for practicing navigation of the Diagnostics menu without connecting to a live vehicle.

Maintenance Features:

Software Updates: The Tech 2 software, stored on a PCMCIA card, can be updated to the latest version using the TIS 2000 Software Download function. Updates include new vehicle system coverage, improvements to diagnostic procedures, and additions of new diagnostic procedures. The PCMCIA card is accessed through a door on top of the unit and should only be removed if instructed by the Techline Customer Support Center.
Screen Brightness and Contrast Adjustment: The [SHIFT] key combined with up and down arrows allows users to adjust the screen display for optimal viewing.
Oil Life Reset: A routine maintenance procedure performed after every oil change to reset the Oil Life Monitor, ensuring the maintenance lamp in the instrument cluster illuminates correctly.
Steering Position Sensor Calibration: A special function to reset the steering angle sensor to 0° after performing an alignment, ensuring proper Electronic Stability Control (ESC) system function.

The Tech 2 is a robust and versatile tool, continuously supported by GM for diagnosing and maintaining a wide range of vehicles, including those from previous model years. While newer tools like the GM Multiple Diagnostic Interface (MDI) are emerging, the Tech 2 remains a valuable diagnostic asset, especially for its dedicated diagnostic applications.
