Index/ Process Checklist

SW tools and Setup Preparation

Before start, we need to assure that we have installed the following SW programs on the computer:

Diagnoser
Ediabas and the .prg file related to BCP21 project(BCP _SP21.prg)

The script needed for automatic cyclical requests:

RTA_transp+Ant_testing.SKR diagnoser Script

Setup and connectors

Power supply and ETH_ACT switches must be switched on in order to supply the part and activate ethernet communications.
Once the part is powered up and ETH_ACT is activated, both LED indicators must be turned on in order to indicate the correct status of the part.
The third switch present on the D-sub connector that is related to the termination resistance is needed if CAN communication is used and some communication issue is present.

Diagnoser Connection

Connect the part and assure that the 2 LED indicators are ON. Open Diagnoser tool and click on Configuration:

Click on Scan for ZGWs and you will find the part’s IP, click on it, then “Apply” and finally “OK”. After that, click on “OPEN”. If the connection is well established, you will see the green window as shown in the bellow image:

Diagnoser Script Selection

Go to Scripting widows;
Click on “Browse” to select the script;
Select
“RTA_transp+Ant_testing.SKR” ‘
Click on “Run script-file” to execute it.

Diagnoser Script Execution

Click OK on both prompts, then the cyclical testing will start. Each group is a complete set of testing

If an error is found, the GROUP will be marked with the red marking and will specify which load is presenting an issue.
For the bellow example, we simulated an open load at the transponder coil and antenna_03. To stop the testing click on “cancel” then “close”.

Diagnoser Script modification (if needed)
The script is a TXT file and can be opened with any editor.

Transponder Coil Function

When the key has a low battery and the car can’t be started via the keyless go function, the key must be placed next to the transponder coil and trigger the communication.
When there is no key placed on the transponder coil and the immobilizer is activated:

If you see that the signal is changed as it is in the last two pies that means the key is identified and the SW will decide if this key is the right key and if the car can be started.
