Parts for your 2018 Toyota Land cruiser-Ignition coils

2018 Toyota LandCruiser ignition coils: are they actually fitted?

For the 2018 Toyota LandCruiser 200 Series sold in Australia and New Zealand, ignition coils aren’t used or relevant. According to Toyota Australia’s 2018 LandCruiser 200 Series model specifications and the Toyota service literature for the 1VD‑FTV 4.5‑litre twin‑turbo diesel V8 (Repair Manual and Electrical Wiring Diagram), the local vehicle is a compression‑ignition diesel with no spark plugs and therefore no ignition coils. You won’t find an “Ignition System” section in the 1VD‑FTV workshop manual, and the owner’s maintenance schedule doesn’t list spark plug or coil replacement.

Why no coils? Diesel engines ignite the air‑fuel mixture by heat from compression rather than a spark. The 1VD‑FTV uses high‑pressure common‑rail injection, electronically controlled by the engine ECU, plus glow plugs for cold starts. That’s a completely different setup to a petrol engine’s coil‑on‑plug ignition.

• Compression‑ignition: fuel ignites from heat, not a spark.
• Key components: high‑pressure pump, injectors, rail pressure sensor, glow plugs.
• No spark plugs, leads or ignition coils to service.

Worth noting: some 2018 LandCruisers in other markets run petrol V8s (e.g., 3UR‑FE 5.7‑litre or 1UR‑FE 4.6‑litre), and those engines do use coil‑on‑plug ignition—typically one coil per cylinder. If your 2018 LandCruiser is an import with a petrol engine, then ignition coils are absolutely fitted and act to step up battery voltage and fire the spark plugs under ECU control. Coils aren’t a scheduled replacement item but can fail with age, heat or oil intrusion, symptoms include misfire under load, rough idle and a check‑engine light. For petrol variants, always replace faulty coils with quality OEM‑spec units, keep coil boots and spark plugs in good nick, and follow the plug replacement interval listed in the factory schedule.

For the AU/NZ 1VD‑FTV diesel, focus servicing on what matters: regular fuel filter changes, clean air filtration, correct oil spec at the prescribed intervals, and attention to injector health and glow plugs if cold‑start performance drops. That’s the maintenance path that keeps a local 2018 LandCruiser happy—no ignition coils required.

FAQs

Does a 2018 LandCruiser 200 in Australia or New Zealand have ignition coils?
No. The AU/NZ 2018 LandCruiser 200 runs the 1VD‑FTV diesel V8, which uses compression ignition with glow plugs and common‑rail injection. Toyota Australia’s specifications and the 1VD‑FTV Repair Manual/Electrical Wiring Diagram confirm there’s no ignition system or coils on this engine.

How can I tell if my 2018 LandCruiser has ignition coils?
Check the engine code and paperwork. If it’s a local 1VD‑FTV diesel, there are no coils. If it’s an imported petrol model (e.g., 3UR‑FE or 1UR‑FE), it will have coil‑on‑plug units—typically one per cylinder. A quick visual check under the engine cover on a petrol V8 shows individual coils mounted on each spark plug.

What should I service instead of ignition coils on the diesel?
Stick to the factory schedule: engine oil and filter at the specified kilometre interval, fuel filter at the recommended change point, air filter as needed, and cooling system checks. Investigate glow plugs if cold starts worsen, and ensure injectors are healthy and correctly coded after replacement—these are the systems that do the “ignition” work on the 1VD‑FTV.
