Notes on HHT advanced information, direction indicator/hazard flasher signal devices diagnosis - AD82.25-P-2000-02A

The driver-side signal-acquisition and actuation module (SAM) (N10/1) and the electronic ignition switch control module (electronic ignition key, N73) plays a part in the direction indicator function.

The direction indicator/hazard flasher function can be checked using the HHT, both  control modules having to be taken into consideration.
