Vehicle inspection
1. inspect speed counter
(1) Use speedometer tester to inspect allowed error of speedometer and action of speedometer
Reference: Km/h
speed indicated by speedometer actual speed
20km/h17-23km/h
40km/h35-40km/h
60km/h55-60km/h
80km/h75-80km/h
100km/h95-100km/h
120km/h 114-120km/h
140km/h133-140km/h
160km/h152-160km/h
Notes: tyre wear or tyre pressure too high or too low will increase error.
(2) Inspect speedometer needle offset
Reference: below 0.5km/h
