Fuses and relays Toyota Premio (T260), 2007–2016

Table of Contents

Most electrical circuits in these Japanese sedans are protected by fuses. High-current consumers are controlled via relays. Protective components (fuses and relays) are housed in fuse blocks located in the engine compartment and passenger compartment.


The diagrams above apply to Toyota Premio (chassis codes NZT260, ZRT260, ZRT261, ZRT265; MC platform) vehicles from model years 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, and 2016 (2WD & 4WD) equipped with 1NZ-FE (1.5 L), 2ZR-FE (1.8 L), and 3ZR-FAE (2.0 L) engines.
