LEAN CARS Central Module JR1801RX-1S-12V for JH101 – 12V 2.4GHz Ride-On Car Receiver Control Board

A child presses the pedal of their ride-on car, but nothing happens. The steering is dead, and the remote control no longer responds. Often, the cause is a failed central control board. This LEAN CARS Central Module JR1801RX-1S-12V is a direct replacement for the control module fitted in the JH101 model, giving a second life to an otherwise perfectly good toy.

This central module acts as the brain of the car. It takes signals from the pedal, steering wheel and the 2.4GHz remote receiver, then drives the main motor and steering actuator accordingly. Designed for a single-motor drive system, it operates on a 12V DC electrical system.

Why choose it

As a genuine spare part from the LEAN CARS range, this control module is manufactured to the same specification as the original component. It bolts into the existing mounting points and plugs directly into the car's wiring loom, using the same connectors. There is no need to modify the chassis or cut any wires. The module also supports the same remote pairing procedure as the original, so it will work with the existing remote control.

Ideal use cases

• Replacing a faulty, damaged or burnt-out control module in a JH101 ride-on car
• Restoring remote control functionality and high/low speed switching
• Fitting as a reliable spare when upgrading the electronics of a similar 12V single-drive kids electric vehicle

Good to know

Installation requires basic wiring knowledge. Disconnect the battery before swapping the module. Ensure all connectors are firmly seated. Match the polarity of the battery wires, and refer to the wiring diagram for your vehicle if needed. The LED indicator on the board lights up when power is connected, and the pairing button is used to sync the remote. This module is intended for use with the original 12V battery and motor system; do not exceed the rated input voltage.
