Timer start of the electric parking heater
A timer control function can be connected to the electrical parking heater which is controlled via the accessory electronic module (AEM).
The system consists of:
- A relay for the electrical parking heater
- Wiring between the relay and accessory electronic module (AEM).
The relay is mounted on the engine block heater and controls the electrical parking heater and relay passenger compartment socket.
The relay acts as a switch and is supplied with power and controlled via the wiring from the accessory electronic module (AEM).
The relay is connected to the ground terminal in the engine compartment.
When post-installing the timer start system for the electrical parking heater the car must be configured using new software which is carried out via VIDA.
There are diagnostics for the relay/control signal.
