Description
Control unit – computer control of the Citroen C -Crosser and Peugeot 4007
Original 4WD control unit (ECU 4×4)-computer control of Citroën C-Crosser and Peugeot 4007. The unit controls the rear axle connection and the torque distribution between the front and rear wheels. If your car reports a 4×4 failure, does not activate the rear drive, the 4WD/lock light flashes or remains only in 2WD mode, the ECU defects is a common reason – especially for older cars.
This module evaluates the signals from the sensors (wheel speed, gas position, stabilization system) and controls the rear axle multi -plane clutch according to driving conditions. It ensures a smooth 4×4 connection and 2WD / 4WD / lock modes (depending on the equipment). A properly functioning ECU improves traction on slippery surfaces, stability of the car and the lifetime of the rear drive clutch.
Installation is a direct replacement for the codes. Compare the label number and connector design before replacement. After installation, we recommend deleting errors, control of power and furnishing, and possibly the basic 4WD system adaptations through diagnostics (diagnlonts, etc.) to communicate with ABS/ESP and rear axle drive. Suitable for professional services and home mechanics.
Compatibility: Designed for 4×4 Citroën C-Crosser and Peugeot 4007 (about 2007–2012). For sure, verify by VIN and codes on the label of your original unit.
