V. Electrical check
1. Instrument cluster doesn’t work
(1) Check steps
1) Check the power (60A) fuse of driver’s cabin (located on the distribution box inside the engine
room). If it is in a normal condition, go to step 2), if not, change the fuse of instrument.
2) Check the live (10A) fuse of instrument cluster (located on the fuse box of instrument desk). If it
is in a normal condition, go to step 3), if not, change the fuse of instrument.
3) Check the ignition (5A) fuse of instrument cluster (located on the fuse box of instrument desk). If
it is in a normal condition, go to step 4), if not, change the fuse of instrument.
4) Check the instrument cluster.
Remove the instrument cluster,① ignition switch on-position, check the voltage between
connector terminals A18, A19 and A20 of instrument cluster and the body, normally around 10～
14V.
Check ② the resistance between connector terminal A9 and the body, normally less than 1Ω. If it
is in a normal condition, replace the instrument cluster, if not, repair or change the wire and
connector.
(2) Check the circuit as shown in Fig. 4-20.
2. Speedometer fault
(1) Check steps
1) Check the power input end of speed sensor.
Ignition switch ON-position, check the voltage between 1-T2 and the body, normally around 10～
14V.
