It sounds like you’re dealing with a frustrating hardware sync issue. When an iProg+ programmer shows "Not Connected" or fails to communicate while powered up, it’s usually a breakdown between the driver, the USB port, or the internal firmware.
). If you see "FAULT - EXTERNAL POWER IS NOT CONNECTED," it often indicates a need for hardware modification. Resistor Replacement:
Quick Summary Checklist:
: The programmer has no power supply or is severely damaged. Light On, No Connection
External Power Supply: Avoid using external power adapters unless specifically required by the script you are running. Drawing power from both the USB port and a 12V DC jack simultaneously can overheat the voltage regulators. 2. Solving the "Not Connected" Software Error iprog programmer not connected hot
For detailed teardowns and specific resistor values, community guides on OBDII365 provide visual walkthroughs for hardware repairs. Programmer is not connected (V1.9.0) - REVELTRONICS
Verify USB Connection: Ensure the cable is directly connected to a PC port, not a hub. Many iProg+ clones draw near the 500mA USB limit, causing voltage drops that trigger connection errors. It sounds like you’re dealing with a frustrating
Run the test to check the health of the internal relays and voltage outputs.
