l Electronic Brake Distribution (EBD): This signal represents the electronic brake proportioning status. This signal is used to indicate a fault with either the brake proportioning system or low brake lamp fluid and illuminate the brake system warning lamp. The signal is originated from the ABS ECU. l ABS Lamp Status: This signal is used to illuminate the ABS warning lamp when an ABS fault occurs. The ABS system will illuminate the lamp when the engine is not running and extinguish it when the engine starts. Further illumination indicates an ABS fault. The signal is originated from the ABS ECU. l Traction Control (TC) Lamp Status: This signal is used to illuminate the TC warning lamp for a bulb check when the ignition is first switched on and also for when TC is active. The signal is also used to illuminate the TC warning lamp when the ABS ECU detects a fault in the brake system for traction control. The signals are originated from the ABS ECU. l Vehicle Speed: This signal is used to operate the speedometer and the odometer and trip functions. The signal is originated from the ABS ECU. l HDC Activity Status: This signal is used to illuminate the HDC active lamp. The signal informs the instrument pack if the HDC function is enabled or disabled. If the HDC function is disabled, the HDC lamp will flash to indicate that the incorrect gear is selected or the vehicle is travelling at excessive speed for HDC operation. The
