Hello, as in the topic of megane III ph1 1.5 dci from 2010 there is no stop. The sensor is ok fuses all good, but which stop I do not know. maybe someone will send a stop scheme from which the pin comes out of the ear and the fuse scheme I would be very grateful thank you in advance for any help.
Diagram of stop lamps attached. 120 - engine control unit 172 - right rear light 173 - left rear light 260 - fuse box 639 - third brake light 645 - UCH 1337 - UPC Apparently the UCH cannot see the signal from the sensor - no plus on the sensor or the signal from the sensor does not reach the UCH. Connect CLIP and check if the signal is coming.
