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

Internal malfunction of
combined instrument

3) Check, repair or replace combined instrument;

Water temperature alarm indicator is not on or
always on

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;

Safety & alarm indicator is not on or always on

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

Brake fluid level alarm indicator is always on
or can’t alarm

Check if oil is sufficient and fill sufficient brake fluid

Insufficient brake fluid

Short-circuit or open circuit of brake fluid
level sensor
