Handbrake Warning Lamp

Warning lamp, handbrake

( P ):

Schematic:

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

If the oil pressure drops below 0.3-0.5 bar, the oil pressure sensor will close and pin 15 on the main instrument unit will be grounded, whereby the control module will turn on the lamp.

When the handbrake is applied, the switch on the handbrake lever will ground pin 14 on MIU so that the control module will turn on the lamp.

If the road speed passes 5 km/h from a speed below 5 km/h while the handbrake is applied, the central warning lamp will also come on and MIU will send a request to SID to activate an acoustic signal.
