Iprog Programmer Not Connected New [patched] May 2026
Troubleshooting Guide: Fixing "iProg Programmer Not Connected" Errors
The iProg programmer is a popular tool among automotive technicians and electronics enthusiasts for odometer correction, airbag reset, and IMMO programming. However, one of the most frustrating hurdles users face—especially when setting up a unit for the first time—is the dreaded "Device Not Connected" or "Hardware Not Found" error.
If you are staring at a red light or an unresponsive software interface, do not panic. This guide outlines the most common reasons why your iProg is failing to connect and provides step-by-step solutions to get you up and running.
Issue: iPROG Programmer Not Connected / “New” Device Not Recognized
2. Software & Driver Layer Analysis
Conclusion
The "iprog programmer not connected new" error is rarely a death sentence for your device. In most cases, it is a Windows driver signature conflict or a COM port mismatch. By disabling signature enforcement, manually assigning COM1, and using the correct software version for your clone, you will resolve the issue within minutes.
If all else fails, your iProg’s physical PIC chip needs re-flashing. Remember: The "(New)" tag is simply the software telling you, "I see a stranger—give me the right keys (drivers/firmware)."
Final Checklist:
- [ ] Test Mode active on Windows.
- [ ] COM port set to 1,2,3, or 4.
- [ ] Correct software version for your hardware.
- [ ] FTDI drivers are legacy (v2.8.30 or older).
By following this guide, your iProg will transition from "Not Connected (New)" to "Device Ready" in no time.

If your iProg+ programmer shows a "Not Connected" status during a new setup, it
usually indicates a driver conflict, a power supply issue, or a hardware-software mismatch often found with clone devices Quick Hardware Diagnostics
Check the LED indicator light on your programmer to identify the problem state: LED is OFF:
The programmer has no power supply or is physically damaged. LED is BLINKING: The programmer is working, but the driver is not installed correctly LED is ON (Solid): iprog programmer not connected new
The programmer is working and the driver is correctly recognized. REVELTRONICS - Forum Common Fixes for New Setups Reinstall USB Drivers
: This is the most common cause. You may need to manually uninstall the current driver from the Device Manager (where it might appear as an "Other Device" or have a yellow exclamation mark) and reinstall the specific driver provided with your software. Use USB 2.0 Ports : Some iProg+ clones have compatibility issues with
(blue ports). Try connecting to a standard USB 2.0 port or using a USB hub. Check the USB Cable
: Faulty or low-quality USB cables can cause intermittent connection errors. Test with a known working high-quality cable to see if the status changes. Serial Number Mismatch
: If you are using specific scripts, the software may require the programmer to have a matching serial number. Some versions allow you to change the serial number via the software to enable compatibility with different script packs. Disable Driver Signature Enforcement
: On Windows 10 and 11, the OS may block the iProg driver because it isn't digitally signed (Error Code 52). You may need to restart Windows in "Disable Driver Signature Enforcement" mode to complete the installation. REVELTRONICS - Forum Software Configuration Ensure the software's iProgPro.ini

It sounds like you’re encountering an “iPROG programmer not connected” error, possibly with the word “new” appearing in the message. This is common when using iPROG (a PIC microcontroller programmer, often a clone of the K150 or similar JDM/ProgPic type programmers) with software like iPROG Programmer Software, WinPIC, PICPGM, or IC-Prog.
Below is a helpful troubleshooting report to resolve this. Issue: iPROG Programmer Not Connected / “New” Device
Step 3: COM Port Assignment
Once the driver is installed and the device appears as USB-SERIAL CH340 (COMx):
- Right-click the device > Properties.
- Go to Port Settings tab > Click Advanced.
- Change the COM Port Number to COM1, COM2, COM3, or COM4.
- Click OK.
Conclusion
The "iProg programmer not connected" error is rarely a fatal device failure. In 90% of cases involving new units, the culprit is a missing CH340 driver, an incorrect COM port number assignment, or a low-quality USB cable. Addressing the USB-to-Serial bridge configuration typically resolves the issue immediately.
When your new iProg+ programmer displays a "Programmer not connected" error, it typically stems from driver installation issues, hardware power failures, or software configuration mismatches. Immediate Troubleshooting Steps
If you are seeing this error on a new device, check these basics first: LED Status Check:
No Lights: Indicates the programmer has no power supply or is physically damaged.
Blinking Red LED: Usually means the hardware is functional, but the driver is not installed or recognized correctly.
Solid Green/Blue: Typically indicates a successful connection.
USB Connection: Connect the device directly to your PC's motherboard ports (on the back for desktops) rather than a USB hub, as hubs often provide insufficient power.
Cable Swap: Faulty USB cables are a common cause of "Not Connected" errors; try a known working cable. Step-by-Step Driver Installation
Most connection errors are resolved by manually installing the specific iProg+ drivers, especially on Windows 10 and 11. Fix Unrecognized USB Device? 12 Solutions (2025) - HP [ ] Test Mode active on Windows
The "Programmer is not connected" error with iProg+ devices typically stems from driver installation failures, power supply issues, or hardware component defects common in clone units. Core Troubleshooting Steps
Driver Verification: This is the most common cause. If the red LED on the device is blinking, it indicates the hardware is receiving power but cannot communicate with the PC.
Action: Manually uninstall the current driver from the Windows Device Manager and reinstall the specific driver version provided with your software. Check the Reveltronics Forum for official driver installation guides. LED Status Indicators: No LED: Programmer is damaged or has no power supply. Blinking Red: Driver is missing or incorrectly installed.
Solid Green/Blue: Programmer is working and correctly connected. Hardware Fixes for Clone Units
Many new iProg+ clone units have "Port Errors" due to incorrect internal components. Common hardware modifications include:
Resistor Replacement: Some units require changing pull-up resistors on the mainboard or adjusting the ADC voltage divider to resolve 10V/12V power errors. MC3406 Resistors: Replacing current sense resistors with variants is often necessary for stable operation.
External Power: Ensure external power is connected when using specific adapters like RFID or UART, as some functions cannot run on USB power alone. Software & System Configuration
OS Compatibility: While newer software versions attempt to support Windows 11, users frequently report "not connected" errors on this OS. Running the software in Compatibility Mode for Windows 7 or 10 is often recommended.
USB Port Power: High-power devices like the iProg+ may struggle with USB 3.0 ports on some laptops (e.g., Surface Pro). Try using a USB 2.0 port or a powered USB hub if the connection is intermittent.
