The vehicle relays information to the driver via the instrument pack. The instrument pack contains lamps and analogue gauges. The colour of the lamp denotes the severity of the information. Warning lamps are red, caution lamps are orange, green and blue lamps indicate a system is operating.
The analogue gauges relay information to the driver such as engine speed, and engine temperature.
Operation
Feed from the battery positive terminal is connected to fusible link 5 of the engine compartment fuse box (C0632-1) by a brown wire. Fusible link 5 (C0570-2) supplies a feed to the ignition switch (C0028-1) on a brown/white wire. With the ignition switch in position ’II’, current flows across the switch (C0094-1) to fuse 3 of the passenger compartment fuse box (C0580-1) on a white wire.
Fuse 3 (C0580-6) supplies a feed to the instrument pack on white green wires to the following gauges;
- The speedometer (C1060-10), which is also fed a signal (C1060-2) from the speed transducer (C0195-1) on a black/red wire. The speedometer (C1060-7) is earthed on a black wire.
- The engine coolant temperature gauge (C1052-3), which is also fed a signal (C1052-2) from the engine coolant temperature sensor via the ECM (C0658-7) on a green/blue then light green/blue wire. The engine coolant temperature sensor is earthed (C1052-1) on a black wire.
- The fuel gauge (C1054-3), which is also fed a signal (C1054-2) from the fuel tank unit (C0114-2) on a green/black then light green/black wire. The fuel gauge earthed (C1054-1) on a black wire.
