If there’s short circuit, broken circuit or poor contact of couplers, replace them with the same-type one.

Check the water temperature alarm indicator to see if it lights after it is connected to ECU (it will light when green/blue wire connected to green wire)
ECU receives the signal and it controls the fan through EFI main relay (the fan runs when ECU is connected with brown and green wire of EFI main relay). If
the water temperature on the outlet of cylinder head is above 92
℃
, the fan runs; if it is below 89
℃
, the fan stops to run.

Remove the front axle to check or replace the speed sensor
Speed sensor is with electronic type and meter is full-electronic meter.
Speedometer and odometer indicate vehicle current speed and accumulative
mileage separately. They are driven by front wheel. Check the speed sensor.
Replace it if necessary.
If there’s fault about speedometer, odometer, tachometer or meter
indicating, it needs to disassemble the meter to check. If the circuit is normal
(no short circuit, broken circuit, poor contact), it needs to replace the meter.
