Toyota Camry XV70 Fuses: Complete Guide & Diagram 2017+

ByAlex Smidt

The Toyota Camry XV70 (2017 and later) uses multiple fuse boxes to protect the electrical systems throughout the vehicle. Understanding the location, rating, and function of every fuse is essential for diagnosing electrical faults, replacing blown components, and performing safe modifications. This guide covers every fuse in each box of the XV70 Camry, including the engine compartment fuse block, the instrument panel fuse box, and the additional relay/fuse centers introduced on this generation.

Fuse Box Locations on the Toyota Camry XV70

The XV70 Camry has three primary fuse and relay centers:

  • Engine Compartment Fuse Block – located on the left side of the engine bay, near the battery
  • Instrument Panel Fuse Box (Driver Side) – behind the lower trim panel on the driver’s left knee area

How to Identify and Replace a Blown Fuse

Always turn the ignition OFF before inspecting or replacing a fuse. Use the plastic fuse puller stored inside the fuse box lid. A blown fuse will show a melted or broken wire element visible through the transparent body. Replace only with a fuse of the identical amperage rating – never use a higher-rated fuse as this can cause wiring fires. The XV70 Camry uses standard ATO/ATC blade fuses throughout the instrument panel box, while the engine bay uses both blade and large JCase/MCASE cartridge fuses for the high-current circuits.

Common Electrical Faults and Associated Fuses on the XV70 Camry

  • OBD port not powering scan tool – check Fuse 6 (15A) in instrument panel box
  • Cigarette lighter / USB not working – check Fuses 9, 10, and 26 in instrument panel box
  • Rear defroster inoperative – check Fuses 12 and 13 in instrument panel box
  • Power windows inoperative – check Fuses 2 and 3 in instrument panel box and IG2 fuse in engine bay
  • No crank / no start – check AM1, AM2, and IG1 fuses in the engine compartment block
  • Pre-collision system warning light – check RDI fuse (20A) in engine compartment
  • Electric power steering warning – check EPS fuse (50A) in engine compartment
  • Headlamps not working – check HEAD LH and HEAD RH fuses (15A each) in engine compartment

Important Notes for the Toyota Camry XV70 Fuse System

  • The 2018 and later facelifts share the same fuse layout as the 2017 launch model; no changes were made to fuse ratings
  • Hybrid variants (XV70h) include additional fuses for the HV battery cooling fan and hybrid ECU within the engine bay block – always consult the hybrid-specific wiring diagram
  • The 120A MAIN fusible link is not serviceable with a standard blade fuse – it requires a genuine Toyota OEM cartridge fuse
  • Always carry spare 10A and 15A blade fuses in the glovebox; these cover the most commonly blown circuits
  • After replacing a repeatedly blown fuse, diagnose the root cause (short circuit, overloaded accessory, water ingress) before inserting a new fuse
