BRAKE WARNING LAMP (See P.B-157.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge unit resistance is small when
the fuel level is high, and the fuel gauge unit
resistance is large when the fuel level is low.
When this resistance rises above a specified
value, the fuel warning lamp illuminates to notify
the driver that the fuel level is low.

DWhen the lubrication system fails after engine
starting, resulting in the oil pressure failing to
build up, the oil pressure switch turns on
causing the oil pressure warning lamp to
illuminate.

DWhen the brake fluid level goes down below
a predetermined level with the ignition switch
in the “ON” position, the brake fluid level switch
is activated or the parking brake switch is turned
on, causing the brake warning lamp to
illuminate.TROUBLESHOOTING HINTS
1. No warning lamps illuminate.
DCheck multi-purpose fuse No.(2).
2. Some warning lamps do not illuminate.
DCheck lamp valve.
DCheck the switches and the gauge unit.
