Description
OEM references S103360001 A and B553717 identify this as a genuine Peugeot ABS and ABR control module for the 806 people carrier. Sourced from a running donor vehicle and tested prior to listing, this is genuine used OEM stock.
The ABS/ABR control module is the electronic brain behind the 806’s anti-lock braking and automatic braking force regulation systems. It continuously processes wheel speed signals from all four sensors to detect impending wheel lock-up during braking. ABS prevents lock-up by pulsing hydraulic pressure at individual corners, maintaining steering control throughout an emergency stop. ABR (Automatic Braking force Regulation) adjusts brake force distribution between the front and rear axles based on load and deceleration, preventing rear-wheel lift or skid and optimising stopping performance for varying vehicle loads. The module communicates with the brake hydraulic unit and instrument cluster via the vehicle’s data network.
Symptoms of a failing ABS/ABR module on the Peugeot 806 include an ABS warning light appearing on the instrument cluster, deactivation of the anti-lock braking or braking force regulation systems, fault codes stored in the ABS control module retrievable by a compatible OBD or Peugeot-specific diagnostic scanner, inconsistent braking performance under hard deceleration, or abnormal brake pedal pulsation during ABS operation.
This unit is in good used condition and is ready for fitment. Always verify the OEM part number precisely against your vehicle’s own reference before ordering. Professional installation is strongly recommended, and the module may require adaptation or coding with Peugeot-compatible diagnostic equipment before it functions correctly in your vehicle. A 14-day return period applies to all orders.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
