OBDSTAR OdoMaster Toyota R7F701441 Mileage Correction

 The OBDSTAR OdoMaster or X300 Classic G3 now supports mileage correction for the following Toyota clusters equipped with the RH850 R7F701441 encrypted processor mcu:

• Toyota BX4
• Toyota BZ4
• Toyota BZ4X
• Toyota Corolla
• Toyota FrontLander
• Toyota Levin
• Toyota Yaris 2020-
• Lexus NX series
• Lexus RX series

   

Here is an example of Toyota Levin R7F701441 Denso cluster mileage correction.

 

Tools required:

OBDSTAR OdoMaster or G3

OBDSTAR P004 bench adapter

High power DC power supply

 

Instructions:

Remove cluster from vehicle.

Go to Toyota- Levin- R7F701441 Denso-Bench mode. (Also supports OBD mode, here we do it on bench.)

Read instructions and connections.

Some models also require 30 pin connector, i.e Lexus NX350.
R7F701442 Denso cluster is not supported yet.

Check bench pinout.

Connect cluster with Odomaster via P004 adapter. Don’t forget to connect with an external power supply.

Read cluster information.
The original mileage is the same as displayed in the cluster dashboard.

Take a screenshot of the original mileage value.

Read eeprom R7F701441 and save.

Start mileage correction.
Read ECU info.
Read the current mileage
If the read mileage differs from the mileage displayed on the dashboard by about 1.6 times, it means that the dashboard of the vehicle is configured in miles. When repairing the dashboard, divide the mileage to be repaired by 1.609433 to repair it.

Enter new mileage you desire to change.

Follow Odomaster prompts to turn on ignition on or off on P004 adapter every time.

Write mileage in process.

Check new mileage. It is the same as the new mileage data on cluster dashboard.

Mileage correction is completed.

Reinstall the cluster back to vehicle.

OBDSTAR DC706 Read Skoda PCR2.1 CS and PIN for All Keys Lost

 In this guide, we’ll walk through the process of reading the CS and PIN code for a Skoda Rapid all-key-lost using the OBDSTAR DC706 tool. This method is particularly useful when dealing with immobilizer and key programming issues.

Step-by-Step Procedure

1. Connect the DC706 Tool

• Select Simos PCR 2.1 Protocol

• Check bench wiring diagram with MP001 or P003+

• Connect ECU with P003+ and DC706

2. Read the CS PIN Code

• First connect ECU and read ECU info. It reads ID successfully.

• Navigate to the "Read IMMO Data" option in the DC706 menu.

• The tool will connect to the server to retrieve the CS and PIN code.

• Once the PIN is extracted, take a screenshot for reference.

Now you can program key with the CS and PIN code.

OBDSTAR Program 2024 Toyota Tacoma All Smart Keys Lost

 This guide demonstrates how to perform an “All Keys Lost” procedure on a 2024 Toyota Tacoma with push-button start using the OBDSTAR. The process involves generating a new smart key, programming it via the vehicle’s smart box, and troubleshooting remote functionality.

 

Tools Required

• OBDSTAR X300 Classic G3/X300 DP Plus

• Toyota 30 PIN bypass cable

• Lonsdor KW100 (for key generation)

• Blank smart key. Here use Lonsdor LT20 smart key (compatible with Toyota’s proximity system)

 

 

Step-by-Step Process

1. Generating a New Smart Key

• Connect the Lonsdor KW100 to the Tacoma’s OBD port.

• Select “All Keys Lost” mode and place the blank key near the smart start button.

• Press the brake pedal to allow the system to read vehicle data.

• The device generates a new key based on the vehicle’s immobilizer information.

2. Accessing the Smart Box

• Locate the smart box (typically behind the dashboard or center console).

• Disconnect the factory wiring harness and connect the OBDSTAR Toyota 30 PIN bypass cable to read “immo data” (immobilizer data).

3. Reading & Writing Immobilizer Data

• Select Toyota > Tacoma (2024) > Proximity System in the OBDSTAR.

• Choose “Read Immo Data” to extract the necessary immobilizer information.

• Reconnect the original smart box harness before proceeding.

4. Generating a Simulator Key

• The OBDSTAR generates a temporary simulator key to bypass immobilizer checks.

• Test the simulator key—the vehicle should power on (though remote functions may not work yet).

5. Add smart key

• Turn ignition ON with the emulator key.

• Select immo data has been backed up and read pin code to program key.

• Wait for confirmation beeps (two beeps indicate success).

• Test the key.
