Direction indicators and hazard warning lights
First check fuse 22 (emergency alarm system) and fuse 29 (direction indicators).
If everything is OK here, check each switch to see if it is receiving power. To do this, remove the switches (chapter "Tools and instruments"). For the hazard warning switch, current should flow to terminal 6, for the turn signal switch, to terminal 4 (ignition on.).
Are the switches OK? Check: Operate the direction indicators, depending on the direction of the turn, the voltage should be at terminal 9 or 3. Operate the hazard warning switch: the voltage should be measured at terminal 11.
Check whether control and flashing pulses are coming from the multi-timer: press the emergency signal switch and take measurements on relays K122 and K123 as described below; there should be voltage on both relays between contacts 1 and 3.
Next, you need to measure the blinking frequency on contacts 4 of both relays (measurement relative to mass)
At the end, both relays remain as the cause of the malfunction. Check as described in the section "Checking the relay" in the chapter "Tools and instruments".
