DESCRIPTION AND OPERATION

88-7

The following table shows the available warning lamps and indicates if they are subject to a bulb check illumination 
and if they are self controlled or externally controlled.

Analogue Instruments
The analogue instruments are:

l

speedometer

l

tachometer

l

fuel level gauge

l

engine coolant temperature gauge.

Speedometer
The speedometer is an electrically driven, analogue instrument for displaying the vehicle speed. The pointer needle 
is oil damped to prevent impacts on the vehicle wheels, causing deflection of the pointer needle.

The speedometer is driven by a square wave signal derived from the ABS ECU. The wheel speeds are measured by 
sensors reading rotational speed from toothed targets on the hubs. These speeds are passed to the ABS ECU in the 
form of pulsed signals. The ABS ECU is programmed that 48 pulses is equal to one revolution of the wheels and this 
equates in distance to approximately 2 metres. The actual signal that drives the speedometer is a buffered signal sent 
from the left hand rear speed sensor.
