The On-board computer (OBD II) doesnt cover all sensors needed for emissions measurement and diagnostic purposes. The ECU thus provides pre-standard OBD II (in Germany: SPI-Test: Stock-Programming-instrument) plugs with CAN, CSx, and J1850 message lines available. For these plugs, and generally for any other diagnostic equipment, Bosch Automotive Service Tools (BAST) provide a special diagnostic cable. The Bosch-designed diagnostic tool BAST d1 offers, among others, the following features:

For all Bosch Lambda sensors (LSU and LSF), the BAST d1 contains an additional internal temperature sensor with integral pre-calibration table. With the help of a pre-calibrated operating temperature the sensor characteristic can be retrieved and evaluated. The special pre-calibrated tables allow a reliable diagnostics of the sensor up to approximately 125 degrees Celsius
BOSCH has developed a solution for harmonic combinations. This is especially suitable for applications where the sensor system is connected electrically to the other vehicle systems by harmonic filters. The BAST d1 makes it possible to determine whether the effect of a harmonic filter is sufficiently effective in the case of harmonic combinations.
BOSCH has developed a special feature for the most recent and / or least recent data value for the maximum and / or minimum current and/or last data value. For this purpose, the BAST d1 contains a temperature sensor and an additional integrated pre-calibrated table. The data can be stored in the memory of the device and can be used for later evaluation.
