1. The direction indicators / hazard warning lamps are controlled by the electronic control unit, which is located on the left under the front panel, above the backlight connector. The location of the block can be detected by the clicks that it makes during operation.
2. During operation of a working unit, clicks should be heard. If any of the direction indicator bulbs stops turning on, the click frequency changes, indicating a problem with one of the direction indicator bulbs.
3. If both turn signal lamps stop flashing, the problem may be a blown fuse, control unit, turn signal switch, or circuit wiring. If the target fuse is blown, repair the short in the target before installing a new fuse.
4. To replace the control unit, disconnect the connector from it and remove the unit from the bracket located behind the front panel.
5. Before installing the block, make sure that the new block is completely identical to the old one.
6. Installation is made in sequence, return to removal.
