The Toyota Passo and Daihatsu Boon are the result of a joint venture between two Japanese automakers to produce a subcompact car in the strategically important 1.0-liter engine class. While the Toyota Passo is virtually identical to the Daihatsu Boon, this project was not a simple rebadging exercise (OEM badge engineering) like their predecessors, the Daihatsu Storia and Toyota Duet (1998–2004). Instead, the Passo and Boon were developed through an equal partnership between Toyota Motor Corporation and its subcompact-car specialist subsidiary, Daihatsu Motor. Toyota spearheaded the initial engineering design, while Daihatsu handled detailed layout, styling, and manufacturing.
This article provides detailed fuse box diagrams and terminal assignments for the Toyota Passo (chassis codes KGC10, KGC15, QNC10; Daihatsu A platform) model years 2004, 2005, 2006, 2007, 2008, 2009, and 2010.

I don't see the pump relay
R6 is the Fuel pump relay
location: Passenger compartment
Where the fuel pump fuse
20 is not a spare. Removing it cuts power to the stereo system.
key locking system playing up, Sometimes will lock all doors and sometimes only locks driers door ,. Is this a fault in locking relay or a main locking module.
