9.4.3.2. Performing OBD Diagnostics
Proceed as follows to perform OBD diagnostics:
1. Select >OBD diagnostics< in the App launcher.
2. Select the requested manufacturer.
3. Select the requested fuel type.
4. Select the requested system.
5. Confirm the selection with >Start<.
6. Observe the info window.
ð The OBD diagnostic process starts.
9.4.4. Parameter
Many of the on-board systems supply digital measured values in the form of parameters for fast troubleshooting. Param-
eters indicate the present state or nominal and actual values of the components. The device displays the parameters al-
phanumerically and graphically.
Example
The engine temperature can be within a range of -30 °C to 120 °C.
If the temperature sensor reports 9 °C but the engine actually has a temperature of 80 °C, the ECU calculates an incorrect
injection time.
A trouble code is not stored, as this temperature is logical for the ECU.
Fault text: Oxygen sensor signal faulty
170
Indication of all emission-relevant parameters. The number of the available
parameters depends on the vehicle.
Indication of ambient data (rpm, coolant temperature) of the stored fault code.
Indication of all permanent trouble codes that are emission-relevant.
Deletion of all trouble codes from "Mode 2/3/7".
Check and evaluation of oxygen sensor function. This mode is not supported at
CAN bus protocols.
Indication of manufacturer-specific parameters.
This mode displays all sporadic and emission-relevant trouble codes.
Here you can actuate the actuators that have been determined by the manu-
facturer as emission-relevant.
Here you can call up vehicle and system information, e.g., the VIN.
Here you can view freeze frame data as well as permanent and sporadic fault
codes.
