Mileage Blockers for Toyota, Honda, Lexus and Acura: Chassis Codes and Clusters
Japanese manufacturers do not organise their cars the way owners do. You think of your car as a 2021 RAV4. Toyota thinks of it as an XA50. That difference is the single most common reason a mileage blocker order for a Toyota, Honda, Lexus or Acura comes through needing to be changed — and it is easy to get right once you know what to look for.
We stock 64 modules across these four brands. This guide explains what actually decides which one fits.
Why the model year on your registration is not enough
Toyota and Lexus identify generations by chassis code, and those codes do not line up neatly with calendar years. A Camry built in late 2023 might be an XV70 or an XV80 depending on when in the year it left the factory. The two use different instrument cluster wiring, so they need different modules.
Here is how that plays out across the range we stock:
| Model | Generations we stock | What decides fitment |
|---|---|---|
| Camry | XV70 (2017–2023), XV80 (2024–present) | Chassis code |
| Corolla | E170/E180 (2012–2018), E210 pre-facelift (2018–2022), E210 facelift (2023–present) | Chassis code plus facelift |
| RAV4 | XA40, XA50, XA60 | Chassis code and cluster type |
| 4Runner | N280, N280 facelift, N380 with 7in display, N380 with 12.3in display | Chassis code plus screen size |
| Highlander | XU50 facelift, XU70 analogue, XU70 full LCD | Chassis code plus cluster type |
| Prius | XW30, XW50, XW60 | Chassis code |
| Tacoma | N300, N400 with 7in display, N400 with 12in display | Chassis code plus screen size |
| Tundra | 2nd gen facelift, 3rd gen analogue speedo, 3rd gen full LCD | Generation plus cluster type |
| Sienna | Analogue, Fully digital | Connector: 40-pin vs 38-pin |
| Sequoia | 2nd gen (2017–2021), 3rd gen (2022–present) | Generation plus cluster type |
| Accord | CV1/CV2/CV3 (2018–2022), CY1/CY2 (2023–present) | Chassis code |
| Ridgeline | Pre-facelift (2017–2023), facelift (2024–present) | Interior facelift |
| Lexus UX | Pre-facelift, facelift | Connector: 40-pin vs 38-pin |
| Lexus NX | Analogue (2014–2020), fully digital (2021–present) | Cluster type |
| Lexus LX | LX 570/450d, LX 600/500d, LX 600/500d/700h | Engine and build date |
Three things decide which module you need
1. The chassis code or generation
This is the main split. On most Toyotas it is printed nowhere the owner normally looks, but you do not need it: the build date on the driver’s door jamb sticker tells you which side of a generation change your car falls on. For a Camry, anything built before the 2024 model year is XV70.
2. The instrument cluster
Toyota changed cluster suppliers partway through several model runs, which is why the RAV4, Highlander, Sequoia, Tundra, Venza and Lexus NX all split on cluster type rather than year. An analogue or half-analogue cluster has physical needles. A fully digital cluster is one continuous screen with no needles at all.
If you can see a real needle sweeping across a printed dial, you have the analogue version — even if there is also a small screen in the middle.
3. The connector behind the cluster
On the Sienna and the Lexus UX, the generations are distinguished by the connector itself: 40 pins on the earlier cars, 38 on the later ones. This is the most reliable check of all, because the connector cannot be mistaken for anything else — but it does mean looking behind the cluster before ordering.
The Land Cruiser 300 deserves its own mention
It comes in three versions: pre-facelift analogue, facelift with the 6.7-inch small digital cluster, and facelift with the 12-inch fully digital cluster. All three are current cars, all three look similar from the driver’s seat, and all three need different modules. Measure the screen or count the needles.
Frequently asked questions
Does a mileage blocker fit a hybrid Toyota?
Yes. The hybrid system and the odometer signal are separate, so a Prius, RAV4 Hybrid, Camry Hybrid or Highlander Hybrid uses the same module as the petrol version of the same generation. The bZ4X and Lexus RZ, both fully electric, have their own modules.
How do I find my Toyota’s chassis code?
You do not need it. Use the build date on the driver’s door jamb sticker, and the cluster type you can see from the driver’s seat. Between those two you can identify any Toyota in our catalogue. If you want the code itself, it appears in the VIN and in the vehicle handbook.
Is installation plug and play on a Toyota or Honda?
Yes — the module connects in line behind the instrument cluster with no cutting, no soldering and no coding. See our cable length guide for whether you want the short or extended harness.
What if I order the wrong version?
Contact us before fitting. We would far rather exchange a module than have you try to make the wrong one work. Send your model, build date and a photo of the instrument cluster and we will identify the right version.
Why do Honda and Acura have fewer versions than Toyota?
Honda keeps cluster architecture more consistent across a model run. The Accord splits at the 2023 chassis change and the Ridgeline at the 2024 interior facelift, but most Hondas — Civic, CR-V, Pilot, Passport, Odyssey — take a single module across the years we list.
Still not sure?
Send us your make, model, build date and a photo of the instrument cluster taken from the driver’s seat. That is genuinely all we need, and it takes us a minute to confirm. It is a much better use of your time than guessing.

Responsible use. These modules are supplied for off-road, motorsport, dyno testing and vehicle development use. They must not be used to alter the recorded mileage of a vehicle being offered for sale. In the United States, 49 U.S. Code § 32703 prohibits disconnecting, resetting or altering a vehicle’s odometer with intent to change the mileage recorded. Please make sure your use complies with the law where you are.
