OBDSTAR RH850/V850 Adapter Kit – Professional Adapter Kit for Airbag, IMMO and Dashboard Systems

Overview

The OBDSTAR RH850/V850 Adapter Kit is a cutting-edge diagnostic and programming tool designed for advanced electronic data reading, decryption, and resetting operations on modern vehicles.
It provides precise access to Airbag, IMMO (anti-theft immobilizer), Dashboard, BCM (Body Control Module), and ELV (Electronic Steering Lock) modules.

This kit is an essential solution for automotive professionals performing complex tasks such as secured data extraction, airbag crash data reset, and AKL (All Keys Lost) key programming across a wide range of vehicle models.

Important:
The RH850/V850 Adapter Kit must be used together with the OBDSTAR MP001 multifunction programmer.
All OBDSTAR tablets must be updated to the latest software version to ensure full compatibility and optimal performance.

FAQ – OBDSTAR RH850/V850 Adapter Kit

Compatibility and Updates

Q: Do I need to update my OBDSTAR tablet before use?
A: Yes. All OBDSTAR tablets must be updated to the latest software version to ensure compatibility with the latest MCU and IMMO functions.

Q: Can the kit operate on its own?
A: No. The MP001 multifunction programmer is required. Some operations also need additional accessories such as the MQB Collector or ECM-001.

Technical Functions

Q: What are the main capabilities of the RH850/V850 kit?
A: It supports IMMO/PIN data reading and decryption, Airbag reset (crash erase), and full management of Dashboard, BCM, and ELV modules with continuous updates for new RH850 processors.

Q: Why does the kit include so many accessories?
A: It covers multiple MCU types (Renesas RH850/V850, D70F35XX, R7F7014XX) to perform advanced secure data operations, IMMO decryption, and AKL key programming across multiple brands.

Volkswagen IMMO V / MQB

Q: What does Volkswagen IMMO V include?
A: IMMO V includes BCM2, MQB, and MLB platforms:

• MQB5A: First generation (V850 processor, Megamos-AES ID88 transponder)

• MQB5B: Second generation (RH850 processor, ID88 transponder)

• MQB5C: Third generation (RH850 processor with encryption core, Hitag-Pro ID5C transponder – in development)

Q: How do I read MQB48-5A/5B dashboards?
A: Use the C4-06 adapter according to the PCB wiring diagram provided. Components may be removed freely for direct access.

Q: How can I identify MQB48-5A/5B (ID88) and MQB49-5C (ID5C) dashboards?
A:

1. Automatic recognition via OBD.

2. Visual check on the PCB: boards marked “EM” or “PCJ” indicate MQB48-5A/5B dashboards.

Q: Is MQB type 5C supported?
A: Not yet. Support for MQB49-5C (ID5C) is under active development by OBDSTAR.

Data Collection and Synchronization

Q: What is the purpose of the MQB Collector?
A: It collects ELV/TCM authentication data directly from the dashboard connector and uploads it to the OBDSTAR server to compute IMMO codes—no need to remove the ELV module.

Q: Is the MQB Collector required for AKL operations?
A: Not strictly, but it speeds up the process significantly. Without it, you must remove the ELV and read D70F3624 data manually using the MP001 and C4-06 adapter.

Q: What’s the difference between blade keys and proximity keys on MQB vehicles?
A: Both are supported. Proximity keys require additional ELV data collection.

IMMO Code Calculation and Synchronization

Q: How is the IMMO synchronization code calculated?
A:

• Blade key: combination of Dashboard CS + ECM CS + TCM CS.

• Proximity key: combination of Dashboard CS + ECM CS + TCM CS + ELV CS.
  All data is automatically sent to OBDSTAR servers for instant online computation.

Q: Are there any costs for synchronization code calculation?
A: No. The service is completely free and available 24/7 through OBDSTAR’s cloud servers.

Accessories and Compatibility

Q: Are additional accessories required for ECU flashing?
A: Yes. For reliable bench work without dismantling, we strongly recommend using complementary accessories (ECM-001, TCM-KIT, MQB Collector, Converter V2).

Q: Is the kit compatible with third-party devices?
A: Yes, as long as the files are unencrypted. Always confirm compatibility with your third-party equipment.
