Jeep Grand Cherokee L Mileage Blocker

Jeep Grand Cherokee L Mileage Blocker for 2022–2026

This Jeep Grand Cherokee L mileage blocker is designed for the WL model from 2022 to 2026 and is intended only for off-road, closed-track and dyno testing. It connects behind the instrument cluster and provides three operating modes: Freeze, Limited and Bypass. Both the Short and Long versions use plug-and-play connections without cutting or soldering.

Compatibility and Instrument Cluster

The module supports all versions of the Jeep Grand Cherokee L (WL) within the stated 2022–2026 year range. There are no instrument-cluster variants that require a different product selection for these vehicles. You do not need to send a dashboard photograph or identify a connector version before ordering this product.

Choose this listing for the Grand Cherokee L model and the years shown above. The compatibility information on this page applies to this vehicle; it should not be used to select a module for a different Jeep model.

Plug-and-Play Installation Behind the Cluster

The installation point is behind the instrument cluster. The supplied mileage blocker connects using its plug-and-play connectors, so the installation does not require cutting or soldering the vehicle wiring. Select the Short or Long version according to whether you want the additional quick-disconnect connection.

Operating Modes: Freeze, Limited and Bypass

• Mode 1 — Freeze: records 0% of the distance travelled while active. One confirmation flash identifies this mode.
• Mode 2 — Limited: records exactly 10% of the distance travelled. For example, 100 km of test distance results in 10 km being recorded. Two confirmation flashes identify this mode.
• Mode 3 — Bypass: records 100% of the distance, restoring normal mileage recording. Three confirmation flashes identify this mode.

The speedometer displays the actual vehicle speed in all three modes. Cruise control and the vehicle's other functions continue to operate normally. Changing modes does not add an extra distance increment to the odometer.

Mode Switching and Memory

With the engine running, flash the high beams five times within four seconds to select the next mode. The confirmation signal flashes once for Freeze, twice for Limited or three times for Bypass. The mode sequence is Freeze → Limited → Bypass → Freeze.

On its first connection, the module starts in Bypass. After you select a different mode, that selection is retained through an ignition cycle. It therefore remembers the last chosen mode rather than returning to the initial setting after every restart.

Short and Long Versions: What's in the Box?

• Short version: a plug-and-play mileage blocker for installation behind the cluster.
• Long version: a plug-and-play mileage blocker with a quick-disconnect connector and an included dummy plug.

The Long version allows the module to be disconnected at the quick connection. The included dummy plug completes the connection for normal vehicle operation without the emulator, avoiding the need to disconnect the installation at the instrument cluster each time.

Is the dummy plug included with both versions?

The dummy plug and quick-disconnect connector are included with the Long version. The Short version is the standard plug-and-play module.
