Description of a chain

Work (inclusion/switching off) of an alarm lamp of ABS the module of management of ABS via ABS lamp drive module in the combined counter operates.

If the anti-blocking brake system in good shape, the module of management of ABS includes an alarm lamp of ABS at turning on of the ignition switch, only 2 seconds allow a lamp to burn and disconnects it. If in system malfunction is found, the module of management of ABS includes a lamp. The lamp also joins the ABS driver module in the combined counter when the socket of the module of management of ABS is disconnected.
