Reprogramming procedure

  1. Check that the application software has the correct program version; see newsletter in TIS2000, which accompanies all software updates.
  2. Update the ICM 3 application software as necessary. It is updated in the exact same manner as SPS programming for other control modules.
  3. Request control module data. Select "ICM3 (OCP)" in the Tech 2 menu to update the OCP software.
  4. Load the software from TIS2000, which in this case is just a "start file" which triggers ICM 3 to start the updating. Note that the unit will be updated in different ways depending on the software which is in the unit from the beginning.
  5. Read and note down the information in the window "Special instructions for the control unit". Note in particular which version of the CD "TIS2000 ICM3" it is that shall be used in the car's DVD player.

    NOTE: Erasing personal data 
    When updating ICM3-OCP with software for integrated telephone the system will format the memory in several partitions. The memory partitions enable the saving of customer settings, such as telephone and address book, in the event of future reprogramming. It will be possible to save the customer settings by selecting "retain personal data" in TIS2000. If it is necessary to erase the customer settings, e.g. with a change of ownership, a reprogramming of the OCP software can be carried out. Select the alternative "erase personal data" when the customer settings shall be erased. The alternatives "retain personal data" and "erase personal data" are first accessible when ICM is updated with software which supports integrated telephone. Other software variants can only be updated by selecting "not partitioned", which results in the whole OCP memory being updated.
  6. Load the CD "TIS2000 ICM3" in the car's DVD player. Use the CD version indicated in step  3 .
  7. Select "Program ECU" in Tech 2. ICM 3 restarts and begins to load the software from the CD in the DVD player. The whole updating process is displayed on the ICM 3 unit's screen.
  8. The programming process is as follows (takes approx. 8 min):
    1. 8.1. The ICM 3 screen goes blank when it restarts
    2. 8.2. A special window with a command prompt opens
    3. 8.3. A status indicator is shown, indicating "Reading Image"
    4. 8.4. "Checking CRC" is displayed, followed by "OK"
    5. 8.5. The text "Upgrading image:..." is displayed
    6. 8.6. A status indicator is shown, indicating "Erasing FLASH"
    7. 8.7. A new status indicator is shown, indicating "Writing FLASH"
    8. 8.8. A new status indicator is shown, indicating "Verifying FLASH"
    9. 8.9. The programming procedure is complete once the "Verify" process is finished.
      NOTE: Steps 8.3 - 8.9 will be repeated once or several times depending on the type of updating carried out. For each repetition one partition is updated. The partition "Application and Language" is largest and takes approx. 85 % of the total time.
    10. 8.10. ICM 3 is restarted again and Tech 2 completes programming.
    11. 8.11. Tech 2 shows "Programming was Successful".
      NOTE: Do not forget to remove the CD from the DVD player and insert the DVD containing map information.
  9. Conclude the updating with an "Add".
