Volvo Car Show mode: Known Issues & Limitations

 

Follow the checklist below if Show mode fails to start;

  1. Make sure the power supply is connected before plugging in the Show mode controller. The controller checks the car voltage during start-up and does not start if it is not connected to the charger or if the voltage is too low.
  2. The car must be completely turned off before inserting the Show mode controller. The wiper stalk must be set to the off position.
  3. Observe the LED’s on the controller during start-up and check according to the PDF / image below.

Show mode LED states, troubleshooting startup issues
Picture showing LED states

Low voltage, 12V battery (LED_12VBAT_FAILURE and LED_12VBAT_WARNING)
The controller will continue to check the battery voltage every 30 minutes and will start Show mode as soon as the voltage is ok (above 12.5V).

Low voltage, High voltage battery (LED_400VBAT_FAILURE)
If the high voltage battery SOC drops to low (approximately 15%, depending on battery model and make) the controller will shut down. Show mode and will not try to restart automatically.

48V battery (LED_48VBAT_FAILURE)
If the SOC on the 48V battery on mild hybrids drops to low, Show mode will initiate a charging process where the 48V battery is charged from the 12V side. If this charging process fails or of the 48V battery stops responding to communication Show mode will shut down and will not restart automatically. To resolve this, unplug Show mode, drive the car to charge the 48V battery and then reinstall Show mode.

Wiper stalk (LED_WIPER_STALK)
Wiper stalk must be in off position when starting Show mode. Unplug Show mode, set wiper to off position and reinsert Show mode.

Wrong mode
If the car is already in Active or Driving mode (by using the car key) when the controller is installed the controller will enter a waiting mode. The LED A or B will flash with green to indicate power is ok but will not enter the initialization phase (with blue flashing).

Sometimes the Show mode system shuts down and the car goes to sleep, why is this happeing?

There are several reasons why this can happen, to start the system again just unplug and reconnect the Show mode controller in the OBD port then check for possible reasons from the list below;

  • If the car has been started with a car key present the Show mode controller has stopped working. To restart the Show mode controller, first remove the key from the car, unplug the controller and reconnect it again.
  • If the Show mode controller detects a low voltage signal from any of the batteries in the car it shuts down the Show mode system to protect the battery. Try to restart Show mode by unplugging the controller and reconnecting it again. Observe the information on the DIM during startup, charging states and potential problems are displayed there. If the startup information does not appear in the DIM follow the troubleshooting section above with respect to the LEDs on the controller to locate the problem.

Can the engine be started in show mode?

No the engine start is blocked and the parking brake is always engaged.

 

I connected everything but the car does not wake up, what can be the reasons?

Check the following things first;

  1. The most common reason is that the Show mode battery charger is not connected. Make sure it is connected before connecting the Show mode controller. Disconnect and reconnect the Show mode controller.
  2. If the battery was discharged it might take some time for the charger to raise the voltage to 13.5 V that is required for the Show mode controller to start. Check the battery voltage or just let the charger work an hour before reconnecting the Show mode controller again.
  3. If there is still no luck? See the Where can I get help section below.

Note! EUCD cars as well as V40, V40CC are no longer supported from version 6.0 and onwards.
