BRAKES

70-22

DESCRIPTION AND OPERATION

The LCM receives the message and illuminates the warning lamp and generates the low brake fluid message for the 
message centre. If the ground signal is momentary, the LCM signals the Instrument cluster of the condition. The 
instrument cluster then informs the ABS ECU over the CAN bus. If the signal is received prior to the activation of the 
pre-charge pump, the pre-charge pump activation is delayed.

If the signal is present for more then 25 seconds, the LCM issues two I BUS messages for the Instrument Cluster:

l

Post “Brake Fluid Level ”in the Message centre

l

Notify the ABS via CAN that the Fluid level has been low for more than 25 seconds.

The ABS ECU immediately switches DSC functions off and continuously illuminates the DSC indicator in the cluster.
