Brake warning lamp

Brake warning lamp

A black/white wire connects the brake warning lamp in the instrument pack (C233-13) to the passenger compartment fuse box (C589-10). Operation of the brake warning lamp is controlled by an earth from the CCU (Australia only), the handbrake switch or the brake fluid level switch:

• When the ignition switch is set to position II (on), the CCU (C593-L) connects the warning lamp to earth (not shown) for approximately 5 seconds to perform a lamp check.
• While the handbrake is on, the warning lamp is connected to earth through the switch fixings, via the black/white wire from the passenger compartment fuse box (C580-13) to the handbrake switch (C091-1).
• If the level in the brake fluid reservoir decreases sufficient to close the brake fluid level switch, the warning lamp is connected to earth through the black/white wire from the passenger compartment fuse box (C582-8) to the switch (C026-3), and the black wire from the switch (C026-1) to earth.

Engine oil pressure warning lamp

Operation of the engine oil pressure warning lamp is controlled by an earth from the oil pressure switch. White/brown wires connect the warning lamp in the instrument pack (C233-12) to the oil pressure switch (C187-1) via the passenger compartment fuse box (C589-5/C581-2). When engine oil pressure₂ is below 0.20 to 0.58 bar (3.0 to 8.5 lbf.in ), contacts in the oil pressure switch are closed and the warning lamp is connected to earth through the switch housing.
