Control Unit Programming Using The "Programming" Menu
- On the PIWIS Tester start screen, call up the → 'Diagnostics'
menu and select the relevant vehicle type.
The diagnostic application is then started and the control unit selection screen is populated.
- Select the control unit to be programmed in the control unit selection screen (→ "Overview" menu) and press [>>] to confirm your selection → see Fig 1.
- When the question "Create Vehicle Analysis Log (VAL)?" appears, either press [F12] to create a VAL or press [F11] if you do not want to create a VAL.
- Press [>>] to acknowledge the message that may appear informing you that campaigns for the vehicle are stored in the PIWIS information system.
- Once the control unit to be programmed has been found, select the → 'Programming' menu.
- Select the → 'Automatic programming' function and press [>>] to confirm your selection and start the guided programming sequence → see Fig 2.
- Read and follow the information and instructions on the PIWIS Tester
during the guided programming sequence. Then press [>>] to continue.
During the programming sequence, the control unit is re-programmed and then re-coded automatically if necessary.
Do not interrupt programming and coding .
Once control unit programming - and coding if necessary - is complete, you will be prompted to switch the ignition off and then back on again after a specified waiting time.
Information
Once programming is completed successfully, the work described under → "General subsequent work" must always be carried out.
If other specific subsequent work is required, this is described in the relevant Service Equipment Information or in the relevant Technical Information.
Information
- If an error message is displayed during programming (e.g. "Campaign does not exist", "No suitable programming rules found" or "Vehicle data could not be read", etc.), please read and follow the appropriate instructions provided under → Troubleshooting .
- If programming is interrupted (e.g. due to a voltage drop or if communication is aborted, etc.) or if programming could not be carried out successfully (error message "Programming unsuccessful"), programming must be repeated .
- If coding is not carried out successfully during the guided programming sequence, the control unit must be re-coded again separately once the guided programming sequence is complete. To do this, select the relevant control unit in the control unit selection screen ("Overview" menu) and press [>>] to confirm your selection. Once the control unit has been found, select the "Codings/adaptations" menu and re-code the control unit using the 'Automatic coding' function .
