FAW R7F7010643 Airbag ECU Repair Guide with OBDSTAR P50

This guide walks you through the complete process of repairing and clearing crash data from the encrypted FAW airbag control module with part number R7F7010643. The procedure uses the OBDSTAR P50 along with the MP001 and RH850/V850 adapter kits.

What You Will Need:
OBDSTAR P50 (or KeyMaster G3)
High-power DC regulated power supply
Main cable
Jumper wires
MP001 Multifunctional Programmer

Step 1 — Update Software and Enter Crash Reset Menu

Before starting, ensure that the OBDSTAR P50 software is fully updated.
Navigate to:
[Crash Reset] ’ [AIRBAG RESET]
Use the search icon (top-right) to quickly locate the correct airbag control module number.

Step 2 — Select Boot Mode and Check Wiring Guide

Tap Start, then choose Boot Mode and the correct adapter (MP001).
This function requires an online server connection—make sure your internet is stable.

Tap [Guide] to view detailed information about the function background, menu descriptions, operation introduction, notes, and connection methods.

Step 4 — Read All Data (Crash Records)

Since crash data cannot be cleared directly, you must first read all module data.

Go to: [Erase Crash (MP001)] ’ [Read All Data (R7F7010643)]

Select the PCB wiring diagram and disconnect the power before changing the adapter.
Replace the MP001 with the RH850/V850 Adapter.
Open the airbag module casing and solder the wires according to the PCB diagram.

Tap [Read All Data (R7F7010643)] ’ [Start]
Wait for communication to complete, then save the backup file.
Operation successful.

Step 5 — Erase Crash Data

Choose [Erase Crash], then follow the prompts to select the correct data file.
The tool will erase crash information from the file.
Crash record cleared successfully.

Step 6 — Reassemble and Clear DTCs

Reconnect everything and switch the device back to Diagnostic Mode.
Select [Erase DTC] again.
This time, the DTC clears successfully.
A final [Read DTC] confirms that the previous crash record is gone.

P50 or Keymaster G3
High-power DC regulated power supply
MP001 multi-function programmer
RH850/V850 adapter kit
Main cable and jumper
SGMW R7F701A033 airbag module

Pre-Operation Preparation
1. Software Upgrade: Ensure your diagnostic tool's software is updated to the latest version.
2. Navigation: From the main menu, select [Crash Reset] and then [AIRBAG RESET].
3. Model Selection: You can quickly locate the correct option by searching for the airbag ECU part number in the upper-right corner search bar.
4. Initial Setup: Select the correct Boot Mode and the corresponding RH850 adapter.

Critical Preliminary Step: Review the Guide
Before any physical work, carefully review the built-in instructions.
Tap the [Guide] button.
Thoroughly read all sections: Background, Menu Description, Operation Description, Notes, and Connection Method.

This information is crucial for a successful and safe reset.

Hardware Connection & Wiring

8. Create Backup: The tool will read the ECU's memory. It is critical to save the backup file when prompted. Wait for the "Operation success" message.

Phase 3: Erasing the Crash Record
1. Execute Erase: Click the [Erase Crash] button.
2. Confirmation Prompt: The device will ask, "Has the [Read All Data] function been executed?" Since you have already done this, select OK.
3. Select Backup File: When prompted, select the data file you saved in the previous step.
4. Completion: The process will complete with a "Crash record erased successfully" message.

Phase 4: Final Verification
1. Reconnect: Reconnect the device to the vehicle and switch the software back to standard diagnostic mode.
2. Clear DTCs: Select [Erase DTC] again. The DTCs will now be erased successfully.
3. Final Check: Perform a final [Read DTC] to confirm. The previous crash record and all related fault codes will be gone.

OBDSTAR P50 vs. SMOK vs. SMARTOBD vs. GromCalc SRS Tool

What's the most recommended airbag reset tool in 2022? Here Obd2shop.co.uk have picked out 4 brands for comparison, to help customers make a reasonable choice.

OBDSTAR vs. SMOK vs. SMARTOBD vs. GromCalc

Difference
1. Price
OBDSTAR P50 < SMARTOBD < SMOK < GromCalcTool
Among them, OBDSTAR P50 is the cheapest, SMARTOBD is little difference, SMOK is higher, GromCalcTool is the most expensive.

2. Coverage
OBDSTAR P50 = SMARTOBD > GromCalcTool > SMOK
Functionally, they're pretty much the same, but the supported vehicle coverage varies. OBDSTAR & SMARTOBD support more than 4300 models, GromCalcTool takes second place, SMOK supports the least.

3. Convenience
OBDSTAR P50 > SMOK = SMARTOBD = GromCalcTool
Only P50 airbag reset tool is a portable Android tablet while the others should connect to a PC. That means Windows system tool depends on computers, which is better to work in shop. In contrast, OBDSTAR P50 can be used anywhere, easy to take along.

4. Accessory
Only OBDSTAR P50 & GromCalcTool are equipped with a high quality universal jumper. SMARTOBD has a general jumper while SMOK does not provide.

5. Update Frequency
OBDSTAR & SMARTOBD are fast while SMOK & GromCalcTool are slower.

Conclusion
To sum up, OBDSTAR P50 is the most cost-efficient SRS tool. As P50 is newly released, it's more intelligent to have wider vehicle range in functions, supports all OBD or Bench methods to reset airbag. Plus steady updates & reasonable price, P50 wins on cost performance.

SMARTOBD CAN Tool is similar to OBDSTAR P50 in function and price, but differs in operating system. Thus, it's less convenient than P50. Also, it needs to pay for annual subscription fee for use. Otherwise, it won't work. View from this aspect, it's less good-value.
