SPEEDOMETER
An E.E.C. decree of 25 June 1976, regulates the speed displayed by the speedmeter in relation to the actual speed travelled.
This decree stipulates :
- The speed indicated by a speedometer must never be lower than the actual vehicle speed.
- Between the speed displayed «SD»and the speed travelled «ST», there must always be the following relationship :
VR < VL < 1.10 VR + 4 Km/h
Example : For an actual speed of 100 Kphthe speed displayed by the speedometer may be between 100and 114 Kph.
The speed indicated by the speedometer may be influenced by :
- The speedometer.
- The tyres fitted to the vehicle.
- The final drive ratio.
- The speedometer drive ratio.
Any of these components can be checked without removing them from the vehicle. (See information note N° 78-85 TT of 19 October 1978).
NOTE :Before replacing the speedometer, check the conformity of the following points :
- The tyres fitted to the vehicle.
- The gearbox final drive ratio.
- The speedometer drive ratio.
