Step-by-Step: Unlocking a Jeep/Dodge 4A Remote

We tested the tool on a locked Jeep/Dodge 4A remote. Here’s how it went:

1. Read the Transponder

Initially, the tool confirmed the remote was LOCKED.

2. Connect the Hardware

Using the Remote Renew Cable, we soldered the remote to the Key Tool Max PRO as per the on-screen diagram.

3. Select the Correct Function

Navigate to:Special Function → Remote Renew → Chrysler & JEEP & Dodge → M3M

4. Begin Unlock Process

Click “Unlock” and wait while the tool processes the remote.

5. Completion

After a short time, the tool displayed “Refresh successful”.

6. Verification

Reading the transponder again confirmed the status was now NOT LOCK.

The Xhorse VVDI Key Tool Max PRO combined with the Remote Renew Cable offers a straightforward, efficient, and reliable solution for unlocking Jeep/Dodge 4A remotes. The process is clear, the hardware is well-designed, and the results are consistent. This tool is a valuable asset for anyone involved in automotive key programming and replacement.

Failed to Adjust Xhorse Dolphin XP007 Clamp Solution

Problem:

The clamp that comes standard on the Xhorse Dolphin XP007 doesn’t work when you try to make micro-adjustments to the screws above the laterality numbers, such as 1 and 2, and the depth numbers 3 and 4. It doesn’t make the micro-adjustments, leaving the key copies defective. It’s impossible to get them adjusted.

Solution:

1. Install two identical probes

2. Install the same blank HON66

3. Adjust the left and right 1 and 2. You need to loosen both 1 and 2 first

4. If the indicator is not turn on, tighten the top screw on that side

Then try again.

How to Solve Xhorse Dolphin II Version Unchanged After Update?

 Problem:

I’ve updated the Xhorse Dolphin XP005L firmware via Xhorse app, but the version remains unchanged in the device after the upgrade. Any solution?

Solution:

Open the bottom cover of the Dolphin II, check the green connector (image below), disconnect it, and proceed with the upgrade again.

Once the upgrade is complete, reconnect the connector.

Xhorse Multi Prog Reset Honda Airbag 77960-TVA-A460-M4 Crash

 This article provides a step-by-step guide on how to reset the crash data stored in the SRS airbag control module (part #77960-TVA-A460-M4) for 2018-2021 Honda Accord vehicles using the Xhorse Multi-Prog Programmer, allowing you to clear the airbag warning light after a deployment or fault.

Disclaimer: This procedure involves sensitive safety systems. Perform at your own risk. A faulty repair can lead to airbag failure. Always verify the part number matches 77960-TVA-A460-M4.

Required Tools & Files

Tool: Xhorse Multi-Prog

Software: Multi-Prog Software (with Honda SRS support)

Files: A known-good “clean” D-Flash file (64KB) from a non-crashed module.

Equipment: Soldering iron, fine gauge wire, Torx and 10mm sockets.

Step 1: Remove the SRS Module

1. Disconnect the vehicle’s battery and wait 10+ minutes.
2. Locate the SRS module under the center console.
3. Remove the safety clip and unplug the electrical connector.
4. Unbolt the module (10mm bolts) and carefully remove it from the vehicle.

Step 2: Prepare the Module for Reading/Writing

1. Open the metal casing of the SRS module to access the main PCB.
2. Identify the correct chip and solder points. The target is the R7F701021 microchip.
3. Solder wires to the necessary points on the PCB as per the diagram below.

Wiring Diagram for Xhorse Multi-Prog:

Multi-Prog Pin	Wire Color (Example)	Function
VCC	Red	Power
GND	Black	Ground
TXD	Purple	Data Transmit
RXD	Blue	Data Receive
RST	Green	Reset
CLK	Brown	Clock

Always double-check the pinout against the chip’s datasheet and your specific board layout.

Step 3: Read & Backup Original Data (CRITICAL)

1. Connect the wires to your Xhorse Multi-Prog.
2. In the software, select: Device -> Honda(Airbag) -> Accord-SRS (2019).
3. Perform a full backup (READ) of all accessible memory areas:

C-Flash

D-Flash (Most Important for Crash Data)

C-Test

D-Test

4. SAVE these files securely. This is your backup if anything goes wrong.

Step 4: Write the Clean Data

The goal is to overwrite the crash data in the D-Flash with a clean file.

1. Source a Clean D-Flash File:

• Extract it from a known-good donor module (preferred method).
• Use a paid online reset service (e.g., carprog.online).

2. In Multi-Prog, select WRITE.
3. Load your clean D-Flash file (the 64KB .bin file).
4. Execute the write command. The process will erase and reprogram the chip.
5. Optional but Recommended: Also write the clean C-Flash file if you have it.

Note: Some memory areas (like C-Shadow) may be locked and cannot be written. This is normal. The D-Flash is the primary target for resetting crash data.

Step 5: Verify and Reinstall

1. Desolder the wires and carefully reassemble the SRS module.
2. Reinstall the module into the vehicle and reconnect the battery.
3. Turn the ignition ON. The airbag light should illuminate briefly and then turn OFF, indicating a successful reset.
4. Use a professional scanner to check for any active SRS fault codes and confirm all system checks pass.

Troubleshooting & Tips

• “Connection Fail” Error: Check your solder connections; they are the most common point of failure. Ensure wires are secure and not shorting.
• Software Detects Crash After Write: Some online file analyzers may give false positives. The true test is the airbag light behavior in the vehicle.
• File Source: Using a file from an identical part number module is crucial. Files are often VIN-specific, but a clean state can be written.
• Always work on a stable, static-free surface and handle the PCB carefully.

By following this guide, you can successfully reset the crash data on a Honda Accord SRS module, turning off the airbag light and restoring the vehicle’s safety system.
