Junction BOX

[Zane87]

HI

Can anyone give any ideas on the junction box?

What all does it control?

I know that it works hand in hand with the computer box and car wont start if faulty

The Junction Box Electronics Control Module (JBE) serves as:
• Gateway Module for vehicle Bus System (provides a pass-through function for
F-CAN)
• Evaluator & transmitter of sensor data for Kombi such as Engine Coolant Level,
Washer Fluid Level, Fuel Level, Hand Brake Contact (evaluated data is transmitted
on to the Instrument Cluster)
• Evaluator & transmitter of sensor data for IHKA such as Automatic Recirculation Air
Control, Coolant Pressure (evaluated data is transmitted on to the IHKA module)
• Activator of Compressor Valve and Rear Window Defogger (activation control data is
transmitted from IHKA module)
• Controller of Wipe/Wash functions, Heated Washer Jets, Seat Heating, Mirror
Heating, Water Valve, Relay 30g_f, Rear Power Windows, Rear Window Sun Shade
• Locking & Unlocking of complete vehicle
• Pass-through for Outside Temp Sensor

What is F-CAN and IHKA?

 

[Ricky318i]

IHKA is basically the Integrated Climate control system of the car. that panel with the heating and cooling controls.
CAN is the Controller Area network used for communicating different equipment in the vehicle (also diagnostics) and F-CAN is the chassis CAN. e.g.: stepper motor for adaptive lights, wiper motor, Steering column stalks, angle sensor.

Ok Cool,

Thanks alot man :ty:

The central locking does not work, at first it did, but only locked, and now nothing,
And the windows are also giving hassles, Front passenger and back behind the driver

Diagnostics will let you know why not. Have it diagnosed by a reputable shop or at a dealership.
