Replacing E-Box

WARNING: Incorrect handling of high-voltage components 
  • Electric shock 
  • Short circuit 
  • Fire 
  • Explosion 

    → Only appropriately trained and authorized persons are permitted to work on high-voltage vehicles and components.

    → Required qualification: High voltage technician or high voltage expert.

    → Observe national requirements and legislation for this work.

    → Always use insulated tools, e.g. > VAS 6883 - Insulated Tool Set  when working on these components. Observe general warning notes for working on the high-voltage system.

    > 2X00IN GENERAL WARNING NOTES FOR WORKING ON THE HIGH-VOLTAGE SYSTEM

NOTE: Voltage drop 
  • Irreparable damage to control unit 
  • Damage to control unit 
  • Fault entries in the control unit 
  • Control unit programming, coding is aborted 
  • Malfunctions in the control unit, even during programming/coding 

    → Switch off ignition bexne disconnecting the control unit.

    → Make sure that the power supply is not interrupted during programming/coding.

    → Connect the battery charger with at least > current 90 A to the vehicle battery.

Information 

The instructions in the Tester  take precedence, since the description may be different with later Tester releases.

The procedure described here has been structured in general terms. Different text or additional information may appear in the Tester  .

Information 

The terms "Ignition on" and "Starting engine" are re-defined for fully electric vehicles (battery electric vehicles - BEV).

Establishing operational readiness/Ignition on: 

Prerequisites for establishing operational readiness: High-voltage battery is sufficiently charged, remove vehicle charging cable from the vehicle charge port, pit driver's key in the emergency start tray.

Establishing operational readiness automatically: Get into the vehicle and close the driver's door. The driver's key is recognized inside the vehicle. Operational readiness is established.

Establishing operational readiness manually: Press Start/Stop switch. The driver's key is recognized inside the vehicle. Operational readiness is established.

Establishing operational readiness/Starting engine: 

Establish operational readiness and engage transmission range. The vehicle is now ready to drive and can be moved.

Ending operational readiness/Switching off ignition 

Ending operational readiness automatically: Get out of the vehicle with the driver's key and close the driver door. The driver's key is no longer detected outside the vehicle. Operational readiness ends.

Ending operational readiness manually: Press Start/Stop switch until the instrument cluster is switched off.

Ending driving readiness/Stopping engine 

Vehicle is stationary: Press the P  button on the instrument cluster. The vehicle is parked.

  1. Disconnect the vehicle from the power supply.

    > Refer to 2X00IN Isolating high-voltage system from power supply/Starting high-voltage system in the appropriate service information.

  2. Connect the Tester to the vehicle and start it. Establish operational readiness on the vehicle.
  3. Place original remote control in emergency start tray.

    Serial number (example)

    1. 11.1  Read off the serial number shown on the high-voltage battery frame and write it down.
    2. 11.2  Select Maintenance/repairs  .
    3. 11.3  Select the serial number coding for the high-voltage battery  .
    4. 11.4  Read and follow the instructions and information on the Tester.
    5. 11.5  Enter new serial number of the high-voltage battery according to menu guidance.
  11. Go back to the Overview  .
  12. In the Overview,  press F7 to switch to the Additional menu  .
  13. In the Additional menu,  select the function Commission component  protection. Follow instructions and procedure.
    1. 14.1  Follow instructions and procedure.
    2. 14.2  Teach component protection according to menu guidance.
    3. 14.3  The tester displays the message: Component protection taught.
  14. Start the vehicle again.

    > Refer to 2X00IN Isolating high-voltage system from power supply/Starting high-voltage system in the appropriate service information.

  15. Read out all fault memories,  process and delete existing faults if necessary.
  16. Exit the diagnostic application. End operational readiness on the vehicle. Disconnect the Tester from the vehicle.
