Volvo FH/FM VECU Control Unit 21067820 20453544 20538393 20554486 24V Euro 5 Computers & Cruise Controls

Description:
This listing is for a used genuine Volvo Vehicle Electronic Control Unit (VECU) with OEM part number 21067820-P01. The VECU is a key electronic module responsible for managing and coordinating multiple vehicle systems on Volvo heavy trucks, including communication between engine ECU, dash, lighting and auxiliary functions. The label identifies it as VECU 27358, 24V, manufactured in Australia, and the module features colour-coded multi‑pin connectors (green and blue) for integration into the truck wiring harness.

According to Volvo and aftermarket truck parts catalogues, part number 21067820 / 21067820-P01 is interchangeable with several other Volvo reference numbers: 20453544, 20538393, 20554486, 20758798, 21313710, 21720407, 85000834, 85003809 and 85013779. These VECU units are commonly fitted to Euro 4 and Euro 5 Volvo FH and FM series vehicles and related FE distribution trucks. A typical application example from commercial listings is Volvo FH12/FH16 trucks around 2005–2010 model years, where the VECU operates on the 24V electrical system and uses the MID144 identifier within the vehicle network.

This specific module has been removed from a working Volvo truck and was function‑tested prior to dismantling. The housing is in good overall condition with some cosmetic marks from normal service. The fixing lugs and connector locks are intact, and the pins inside the green and blue plugs show no corrosion or heat damage. The original Volvo identification label with barcodes, serial number and part number 21067820-P01 is present and readable, which is important for correct programming and matching during replacement.

Item is ideal as a replacement part for a faulty or water‑damaged VECU on compatible Volvo FH, FM or FE trucks where the original unit carries one of the cross‑reference numbers listed above. In most cases installation will require copying or programming the existing configuration using suitable Volvo diagnostic equipment (e.g. Tech Tool) so professional fitting is strongly recommended. Please compare your existing part number and connector layout with the photos and reference list to confirm compatibility before purchase.

The module is sold as a used but tested control unit only, without additional wiring, brackets or mounting hardware. It has been cleaned externally after removal and will be shipped well packed in anti‑static and protective packaging. A 3‑month warranty is provided against electrical failure under normal use, and we offer a 30‑day return period if the part is not suitable (buyer is responsible for return postage).
