Speedometer

The handbrake/low brake fluid warning lamp receives a constant battery feed from fuse 14 of the passenger compartment fuse box (C0589) on a P wire. Illumination of the lamp is controlled by the handbrake switch (C0091) on a BW wire. When the handbrake is applied, the switch contacts close and an earth path is created, illuminating the lamp. Illumination of the lamp is also controlled by the ABS ECU (C0500 on 01MY vehicles, C0501 on 02MY vehicles) via the CAN BUS on YN (Low) and YB (High) wires. If the warning lamp is illuminated while the handbrake is released, urgent attention is required to the braking system. The low oil pressure warning lamp receives an ignition feed from fuse 8 of the passenger compartment fuse box (C0589) on a G wire. Illumination of the lamp is controlled by the oil pressure switch (C0187) on a WN wire (WN then NG on Td4 vehicles). The ignition/no charge warning lamp receives an ignition feed from fuse 8 of the passenger compartment fuse box (C0589) on a G wire. Illumination of the lamp is controlled by the ECM (C0331) on Td4 vehicles, and the alternator (C0053) on K1.8 and KV6 vehicles. The anti-theft alarm LED receives a constant battery feed from fuse 14 of the passenger compartment fuse box (C0589) on a P wire. Illumination of the lamp is controlled by the CCU (C0592) via the passenger compartment fuse box (C0589) on a UK wire. The overspeed warning lamp receives a constant battery feed from fuse 14 of the passenger compartment fuse box (C0589) on a P wire. Illumination of the lamp is controlled by the ABS ECU (C0500 on 01MY vehicles, C0501 on 02MY vehicles) via the CAN-BUS on YN (Low) and YB (High) wires.

NOTE: The overspeed warning lamp is not operational in all markets. The cruise control warning lamp receives a constant battery feed from fuse 14 of the passenger compartment fuse box (C0589) on a P wire. On KV6 vehicles, illumination of the warning lamp is controlled by the cruise control ECU (C0239) on a WU wire. On Td4 vehicles, illumination of the warning lamp is controlled by the cruise control interface unit (C1959) via the CAN-BUS on YN (Low) and YB (High) wires.

NOTE: The list of CAN-BUS connections is by no means exhaustive. For more details, refer to the 'Communication Databuses' and 'Instruments' sections of the System Description and Operation Workshop manual.

Speedometer

The speedometer is driven by a CAN message from the Engine Control Module (ECM) on YN (Low) and YB (High) wires. For more information on speedometer operation, refer to the Instruments section of the System Description and Operation Workshop manual.

Tachometer

The tachometer is driven by a CAN message from the Engine Control Module (ECM) on YN (Low) and YB (High) wires. For more information on tachometer operation, refer to the Instruments section of the System Description and Operation Workshop manual.
