Hill Descent Control (HDC) fault warning lamp
The HDC fault warning lamp within the instrument pack utilises an amber LED and a clear legend. On vehicles fitted
with hill descent control the SLABS ECU illuminates the LED if a fault within the HDC system is detected, providing
the driver with a visible warning.
When the ignition is switched on, the SLABS ECU illuminates the LED to provide a self-check, it will remain illuminated
for 3 seconds or until the ignition is switched off, providing there is no fault.
The power input for the LED is supplied by the instrument pack via fuse 27. The SLABS ECU provides the earth path
to illuminate the HDC fault warning lamp
The voltage on the earth path from the SLABS ECU to the instrument pack has the following functions:
l

< 1.8 volts = warning lamp is switched on.
> 7.7 volts = warning lamp is switched off.
