What makes up a junction box in a car?
In the junction box, the power distribution box and junction box electronics form a unit. The junction box electronics is the central gateway in the vehicle. The junction box consists of the power distribution box and the junction box electronics. The junction box electronics unit combines numerous functions in a single control unit.
Where are the relays located in a junction box?
All internal relays and the relay for wiper stage 1 and wiper stage 2 are located downstream of the fuse on the current path. All other external relays of the junction box electronics lie in the current path before the fuse. Relay for the central-locking drive (except for tailgate)
How does a seat module work in a junction box?
A seat module is always installed with seat memory. The junction box electronics (JBE) send a prompt to determine whether a seat module is installed. If the junction box electronics do not receive confirmation, the junction box electronics handle activation of the seat heating. The junction box electronics generate a pulse-width modulated signal.
How is the junction box connected to the dashboard?
The junction box electronics unit is connected via 4 plug connections. A 54pin connector is for the connection to the dashboard. Two further connectors are for the connection on the main wiring harness. These are 54pin and 47pin connectors. A 23-pin internal plug connection connects the junction box directly to the power distribution box.
Where are the plugs in a junction box?
A 23-pin internal plug connection connects the junction box directly to the power distribution box. The fuses and various plug-in relays are located in the junction box power distribution box.
