No. 222 Electric mirror can’t work   

Malfunction Cause 

Solution 

Switch parts of mirror 
damaged 

Check contacts of mirror control switch and contacts of left and right adjusting 
switches for circuit break due to burn-out or too dirty; if yes, clean them or 
replace switch parts; Check left and right adjusting switches for blocking; if yes, 
switch parts should be replaced.   

Poor contact, short-circuit 
or open circuit of harness, 
connecting wire and 
connectors  

Check connector of mirror switch parts for loosing or dropping-off; Check 
connector of mirror motor for loosing or dropping-off;   

Power supply for mirror   

Disconnect connectors of mirror switch parts and measure voltage of its power 
supply; find power supply wire and measured voltage should be 12 – 14 V; if 
there is no voltage, fuse should be checked for burn-out; check if the resistance 
between bond strap at mirror switch parts and body should be zero, otherwise 
look for the line or tighten it up again; check if there is break between points of 
harness connection and measure the resistance; it should be zero as conducting 
state.  

 
Electric mirror 
can’t work 

Malfunction of mirror motor   

Check mirror motor for sign of burn-out and measure by multi-meter if the 
resistance of motor is in normal range; if the resistance is infinite, thus the motor 
is burnt or broken internally and should be replaced; check with power on: 
disconnect connector of mirror motor; connect positive and negative poles of 
external power supply to connectors of motor output and view if motor is 
actuating; if not, it shows that motor has been broken internally and the electric 
mirror should be replaced.

No. 223 Always-On or failure of water temperature alarm indicator   

Malfunction Cause 

Solution 

Malfunction of cooling system 

Check cooling system for sufficient coolant and normal recirculation of 
coolant;  

 

Malfunction of water 
temperature sensor   

The water temperature sensor is negative thermostat-type; measure its 
resistance variation under different temperature and working condition and 
compare them to standard values; check, repair or replace water 
temperature sensor;   

Malfunction of wire   

2) Check, repair or replace electric harness;   

Water temperature 

alarm indicator is 

always on or isn’t 

on 

Internal malfunction of 
combined instrument   

3) Check, repair or replace combined instrument;   

 

Water temperature alarm indicator is not on or 
always on 

Is electric fan working? 

Cooling system 

Measure with multi-meter for 
resistance variation 

Malfunction of water

No. 224 Safety & alarm indicator is always on or not on   

Malfunction Cause 

Solution 

 

Seat belt unlocked (always-on)   

Snap-on the seat belt   

Break (not on) or short-circuit (always-on) of 
internal circuit board for seat belt snap-on lock   

1) Check and repair internal circuit board for seat belt 
snap-on lock, or replace seat belt assembly   

Malfunction of loop   

3) Check if switching loop for snap-on lock of seat belt 
is broken or short-circuit;   

Safety & alarm 
indicator is always 
on or not on 

Internal fault of combined instrument   

2) Check, repair or replace instrument assembly;

No. 225 Brake fluid level alarm indicator is always on or can’t alarm   

Malfunction Cause 

Solution 

Insufficient brake fluid results in always-on of brake 
fluid level alarm indicator   

Fill sufficient brake fluid   

Short-circuit or open circuit of brake fluid level 
sensor  

Replace brake fluid level sensor   

Short-circuit or open circuit of connection between 
brake fluid level sensor and instrument results in 
always-on of brake fluid level alarm indicator   

Short-circuit of brake fluid level alarm indicator results in 
always-on of its indicator.   

Brake fluid level alarm indicator can’t alarm 

Break of circuit for brake fluid level alarm indicator or failure of 
buzzer for alarm circuit   

Internal fault of combined instrument   

Check, repair or replace combined instrument.   

Failure of brake fluid level 
alarm indicator is always 
on or can’t alarm 

Fault of ABS system (indicated together with ABS 
fault indicator)   

Repair ABS system
