I disconnected the yellow connector EM02
I measured voltage on pins 6,7 and 8 under different stalk switch conditions
If you have disconnected the connector you need to be sure your measuring the voltage on the correct side. The diagram shows the power supply is on the female side of the connector. Is that the side you were probing with your meter?
Switch at left turn: pin 6 alternating 12 v, 7 & 8 0 V Fast left dash light flash
That's interesting. The turn signal circuit isn't connected to pin 6 of EM02, according to the diagram.
Hazard switch on: 0 v on all pins Fast right dash flash (no left)
Interesting too that the left tell tail (dash warning light) isn't working when the hazard lights are on.
Did you look to see if the left turn signal on the rear of the car was working? I'm guessing not since the flash rate was fast.
If the rear left turn signal isn't working when the hazard lights are on that is pointing to a fault with the hazard switch.
But that can't be the cause of the front lamps not working, which I think should be pretty clear from the diagram.
is the problem the stalk switch or the hazard switch?
The problem with the front lamps can't be caused by a fault within either switch.
But you seem to have stumbled across fault within the hazard switch that is unrelated to the problem with the front lamps.
