DESCRIPTION AND OPERATION

Self Levelling Suspension (SLS) warning lamp

The SLS warning lamp within the instrument pack utilises an amber LED and a clear legend. The SLABS ECU 
illuminates the LED continuously if a fault within the SLS 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, providing there is no 
fault it will remain illuminated for 3 seconds or until the ignition is switched off.

On vehicles equipped with coil springs the SLS warning lamp is extinguished after 850 milliseconds if the SLABS ECU 
configuration of the vehicle is correct.

The SLS warning lamp flashes at 2 Hz when the remote handset control is used to raise or lower the ride height.

If a new SLABS ECU is installed the SLS warning lamp will remain illuminated until the ECU has been calibrated by 
TestBook.

The warning lamp will illuminate continuously when battery voltage is less than 10 volts for greater than 1 second.

When the vehicle is in transportation mode the SLS warning lamp is illuminated continuously with ignition on, and will 
flash at 2 Hz frequency as the vehicle rises from bump stop level to transport level on engine start.

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 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 on.

l

> 7.7 volts = warning lamp off.
