Volvo Service Bulletin 3-37-26

Wiring diagrams for Volvo B10M Mk I from chassis 8030

Due to modifications and production changes there were a number of different wiring diagrams released for the the B10M Mk I. This Service Bulletin applied from chassis number 8030 up to the next wiring diagram.

The tables below are based upon information published in Volvo Service Bulletin 3-37-26. The Service Bulletin included the drawings 1193990P02 (B10M Mk I) and 1193991P02 (B10M Mk I Articulated). These drawings are basically limited to symbols with component numbers and require the component description to give meaning to the diagrams. The first table below is sorted by the Component Number field and is used to interpret the component numbers on the drawings. While the second table is sorted by the Description field and used to find a particular component on the drawings.

The letter and digit in brackets indicate the box where the component is situated. Connection points marked on the wiring diagrams with a brown arrow are intended for the bodybuilder.
