Warning Lamp, Handbrake

Warning lamp, handbrake

P:

Schematic:

The handbrake warning lamp is situated on the RH side of the main instrument unit and informs the driver if the handbrake is applied.

If the oil pressure falls below 0.3-0.5 bar, the oil pressure sensor makes contact, pin 15 in the main instrument unit is grounded and the control module turns on the lamp.

When the handbrake is applied, pin 14 on MIU is grounded by the contact on the brake lever handbrake lever, which means that the control module turns on the lamp.

If the speed exceeds 5 km/h from a speed lower than 5 km/h when the handbrake is applied, the central warning lamp comes on and MIU sends a request to SID to activate the acoustic signal.
