Checking Battery In Control Unit For External Communication

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, put 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.

3. Select the Connect  control unit in the overview.  Press F12 to continue. The message "Create Vehicle Analysis Log (VAL)?" appears. Press F11 to continue.
4. Actual values/input signals  must be selected.
5. Select General. 
   1. 5.1  Select Battery for emergency call module: State of charge. 
   2. 5.2  If the state of charge is > 80%, continue with Step  7.
   3. 5.3  If the state of charge is < 80%, continue with Step 6.
6. Select Emergency call system battery: Charging status. 
   1. 6.1  If charging status is "charging", continue with Step  3.
   2. 6.2  If charging status is "not charging", continue with Step 7.
   3. 6.3  Wait 5 minutes.
   4. 6.4  If the state of charge is increased, continue with step 7.
   5. 6.5  If the state of charge is not increased, replace battery in control unit for external communication.
