Description of Activations

Description of activations

Relay engine block heater
Control module terminal #5 for the engine block heater relay can be activated. In the normal position (the output not activated by the central electronic module (CEM)), the voltage is approximately 0 V. On activation, the voltage is approximately equivalent to battery voltage and the relay for the engine block heater is activated. If the heater or other accessory is connected, it should start.

Alarm, output signal P0
Control module terminal #15 for the alarm, output signal P0, can be activated. In the normal position (no alarm triggered), the voltage is approximately equivalent to battery voltage. On activation, the voltage is approximately 0 V.

Alarm, output signal P1
Control module terminal #16 for the alarm, output signal P1, can be activated. In the normal position (no alarm triggered), the voltage is approximately equivalent to battery voltage. On activation, the voltage is approximately 0 V.

Alarm, output signal S0
Control module terminal #33 for the alarm, output signal S0, can be activated. In the normal position (no alarm triggered), the voltage is approximately equivalent to battery voltage. On activation, the voltage is approximately 0 V.

Alarm, output signal S1
Control module terminal #34 for the alarm, output signal S1, can be activated. In the normal position (no alarm triggered), the voltage is approximately 0 V. On activation, the voltage is approximately equivalent to battery voltage. The function is reversed compared to output signals P0, P1 and S0.

Carphone mute signal
The carphone mute function can be activated. The accessory electronic module (AEM) transmits a request to lower the sound level to 0 (mute) via the CAN network to the infotainment control module (ICM).
