Step-by-Step Guide to Mileage Correction

  1. Remove and disassemble the cluster

Remove the instrument cluster from the vehicle and carefully disassemble it to access the R7F701441 processor.

  1. Prepare the cluster for correction
    Follow the wiring diagramin the CG100X software to power on the instrument cluster.

The mileage will initially display as 0 km because it’s a brand-new cluster.

  1. Select thecorrespondingmodel

In the CG100X software
Navigate to Dashboard>> Toyota>> Frontlander>> R7F701441

  1. Viewthe wiring diagram
    The processinvolves removing 4 capacitors (280nF) from the cluster. Follow the wiring diagram for the exact locations.

  1. Connect CG100Xand Cluster

Connect CGDI CG100X and the cluster using the D1 Adapter (required for the RH850 processor reading)

Do not extend the D1 adapter cable

Make sure the 12V power supply is connected to power the cluster during the process.

  1. Read chip ID
    After connection,read the chip ID to verify the processor.
  2. Read and save data
    Read Dflash and Pflash dataseparatelyfrom the processor, and save the corresponding data

  1. Calculate mileage by the built-in algorithms
    TheCG100Xprogrammer comes with built-in algorithms tailored for the R7F701441 processor. Make sure your device is connected to the internet so that these algorithms can calculate the actual mileage online.
  2. Verify the current mileage
    Check the current mileage displayed on the cluster and verify it.
  3. Input the new mileage
    Inputthe newmileage you desire.

For example, enter the mileage value 35554 (KM)

Then click “OK”

  1. Write the new mileage data

The new mileage data will be written to the cluster by CGDI CG100X.
Wait a while until the process is complete

  1. Reassemble the Cluster
    After the new mileage is written, disconnect the wires and solder the 4 capacitors back onto the cluster
  2. Verify the New Mileage
    Power on the cluster and check if the mileageon the cluster is the same as CG100X software.
