After installation, Device Manager should show:
Ports (COM & LPT)
└── iPROG Virtual COM Port (COM3)
The iPROG software should now display "Connected".
iProg Pro requires external 12V DC power (not just USB).
Final Note: When dealing with a new iProg, patience is key. The relationship between the software, the drivers, and the Windows operating system is delicate. Following the driver installation process manually—rather than relying on automatic Windows updates—solves 90% of "Not Connected" errors.
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 iprog programmer not connected new
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.
For detailed teardowns and specific resistor values, refer to repair guides on OBDII365.
Does your device show any lights when plugged in, or is it completely dark? How to Repair iProg+ Clone Port Error?
If your new iProg+ programmer is showing a "Not Connected" error, it is almost always a result of driver installation issues or operating system incompatibility.
Follow this guide to troubleshoot and resolve the connection error. 1. Verify OS Compatibility
The iProg+ software is notoriously picky about operating systems.
Recommended OS: Windows 7 (32-bit) is considered the most stable and "guaranteed" environment for iProg+.
Windows 10/11: While newer versions like V89 are designed for Windows 10, stability is not guaranteed. Users often report the "Not Connected" error on Windows 10/11 even if drivers appear installed.
Pro Tip: If you must use Windows 10, try running the software in Compatibility Mode for Windows 7. 2. Proper Driver Installation After installation, Device Manager should show: Ports (COM
The device is often seen as an "Unknown Device" in Device Manager if drivers aren't manually pointed to the software folder.
Connect the iProg+ unit to a USB 2.0 port (USB 3.0 ports sometimes cause communication lag).
Open Device Manager. Look for "iProg" or "Unknown Device" under Other devices or Ports (COM & LPT).
Right-click the device and select Update Driver -> Browse my computer for drivers.
Navigate to the Drivers folder within your iProg software directory (e.g., iProg_Pro_V87\Drivers) and click OK. Restart your computer after installation. 3. Hardware Power & Connections IPROG Pro V87/V89 Universal Programmer Instruction Manual
is a multi-functional automotive tool used by technicians for tasks like mileage correction, airbag resetting, and key programming. A common technical hurdle for new users is the " Programmer not connected
" error, which typically stems from driver mismatches or power issues rather than hardware failure. Quick Fix Guide: "Programmer Not Connected"
If you see this error message, follow these troubleshooting steps in order: Check Windows Compatibility : iProg software often struggles with Windows 10/11 . It is highly recommended to use Windows 7 32-bit for the most stable connection. Driver Reinstallation
: The error is most frequently caused by an incorrectly installed driver. Device Manager devmgmt.msc ) and look for the programmer in the device tree. Uninstall any existing iProg drivers.
Reinstall the drivers provided with your software version (e.g., V87 or V89) and restart your computer. USB Port Power : iProg is sensitive to power drops. If you are using a The iPROG software should now display "Connected"
, the device may not receive enough current (500mA limit). Connect the programmer
to a different USB port on your laptop to rule out power-related disconnects. Software Version : If version fails to connect, try downgrading to
, which is widely cited as the most stable version for Windows 7 systems. At a Glance: iProg Pro Review IPROG Pro V87/V89 Universal Programmer Instruction Manual
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.
Follow these solutions in order. Do not skip steps.
If you have tried all software fixes and the device is still not detected, you may be facing a hardware fault.
New iProg units often require manual driver installation.
If the software says "(New)" specifically, the iProg might be in bootloader mode or have empty flash.
Required: A second working programmer (like a MiniPro TL866 or another iProg) to re-flash the PIC chip.
Note: If you do not have a second programmer, contact your vendor for a pre-flashed replacement chip.
