Just joined this forum. I have found a workaround to stop the flashing indicators when switching headlamp to LED. 2 resistors need to be replaced on the ICM PCB. After that the indicators act normal again.
In the ICM module there are 2 specific resistors, measuring the current in the headlight lamp, low and high beam. These 2 resistors are located on the right side of the print. The voltage over the resistor goes into the main processor on the board. The voltage on the input pins with normal bulb is about 1.9V. With the Led lamp only 0,6V. So the input is not active. The resistors are 8k2 standard. To get the 1.9V on the inputs i had to increase the resistors to 33K.('333' in SMD). The voltage is then around 2V and the flashing stops.
Feel free to ask or comment
