15.3.1. Overview

The Turn Signals Stalk Driver component processes the signals from the turn indicator stalk and determines the requested turn indication (left, right, none). It handles both single-pin and dual-pin stalk configurations.

15.3.2. Functions

Title

Description

1

Process Single-Pin Stalk

Determines the turn indication request based on the resistance value of a single-pin turn indicator stalk. Detects stalk failures.

2

Process Dual-Pin Stalk

Determines the turn indication request based on the on/off states of the left and right switches in a dual-pin turn indicator stalk. Detects stalk failures.
