64Chapter 9 General Engine Troubles and Their
TroubleshootingSection 1 Overview The wide application of the electronic technologies to the vehicles brings innovation on diagnosis of the
vehicle, many varieties of diagnosis instruments that are very effective and efficient for the vehicle diagnosis
are innovated. Once the fault occurs, the best choice is to go to service station for help. However, even the
most advanced instrument has its limit. For some faults, manual diagnosis is far more convenient and easier
than that of instrument. In case of the crack, distortion and leakage of the components, the manual diagnosis
is even superior to the instrument diagnosis. The faults occurred shall be carefully analyzed and troubleshot
in accordance with the repair manual for normal usage.Section 2 General Engine Fault and TroubleshootingI. Fuel pipeline and circuit fault causing the engine starting failureengine starting failure normally include: starter does not run or starter runs but fails to crank the engine, or
cranks the engine but cranks slowly; starter can crank but fail to start the engine. There are many causes that
result in starting failure, such as failures in starting system, ignition system, fuel injection system and engine
mechanical failure.
1. starter does not run or fails to crank the engine or cranks slowly
(1) Symptom: starter does not run or spongy rotation
(2) Causes:
b. Low battery voltage, excessive battery discharge, damaged generator or failure in charging circuit;
c. Battery terminal rust and backed out;
d. Failure in starting circuit, ECU can not receive STA signal;
e. Damaged starter.
2. engine can not start and crank
(1) Symptom
With the start switch on, starter can crank but fail to start the engine.
(2) Causes
a. Empty fuel tank;
b. Electrical fuel pump inoperative;
c. Injector inoperative;
d. Low fuel pressure;
e. Unreasonable starting operation;
f. Damaged throttle position sensor or no signal is sent to ECU due to the open in throttle position
sensor circuit;

(MR479Q MR479QA MR481QA)I. STARTER INSPECTIONNOTICE:
These tests must be done within 5 seconds to avoid burning out the coil.
1. INSPECT MAGNETIC SWITCH
(a) Use wire to connect the starter as shown.
(b) Connect the magnetic switch and the battery as
shown.
(c) Disconnect the magnet exciting coil from the
terminal A.

166II. CHARGING SYSTEM INSPECTION1. CHECK BATTERY WORKING VOLTAGE
(a) After having driven the vehicle and in the case that 20 minutes have not passed after having stopped the
engine, turn the ignition switch ON and turn on the electrical system (headlight, blower motor) for 60
seconds to remove the surface charge.
(b) Turn the ignition switch OFF and
turn off the electrical systems. Then
measure the battery voltage
between the negative and positive
terminals of the battery.
Standard voltage: 12.5-12.9V at
20°C
HINT:
If the voltage is less than specification, charge the battery.
2. CHECK BATTERY TERMINALS, FUSE BOX AND FUSE
(a) Check that the battery terminals are not loose or corroded.
(b) Check if fuse box and fuse for continuity.

1687. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a battery/starter tester is
available, connect the tester to the
charging circuit as per instructions.
(b) If a tester is not available, connect
an ammeter and voltmeter to the
charging circuit as follows.
1Disconnect to the wire from
terminal B of the alternator and
connect it to the negative (-) pole
of the ammeter.
2Connect the positive (+) pole of the
ammeter to terminal B of the
alternator.
3Connect the positive (+) pole of the voltmeter to terminal B of the alternator.
4Ground the negative (-) pole of the voltmeter.
(c) Check the charging circuit
yWith the engine running from idle to 2,000 rpm, check the reading on the ammeter.
Standard amperage: 10A or less
Standard voltage: 13.2V---14.8V
8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high beam headlights and place the blower switch at "4".
Check the reading on the ammeter.
Standard amperage: 20A or more
(b) HINT:
yIf the ammeter reading is less than standard amperage, repair the alternator.
yIf the battery is fully charged, the indication value will sometimes be less than standard amperage.Ammeter

1Turn the ignition switch to LOCK.
2Disconnect the negative (-) terminal cable from the battery.
3Disconnect the connector of instrument cluster.
4Check if the related circuits of the warning light are connected or not.
Yes: continue with next step.
No: replace the wire harness, and then continue with step 5.
2. SRS warning light remains on.DIAGNOSTIC PROCEDURESTo begin the check, first use special diagnostic instruments and ECU to perform communication diagnosis
and find out the causes of the trouble. If the communication fails, continue with the following procedures:
(1) Check battery
1Check battery voltage.
2Is voltage higher than 9V?
Yes: continue with next step.
No: Insufficient battery supply. Check the charging/discharging system, and then continue with step (5).
(2) Check the continuity of the wire harness between ECU and instrument cluster
1Turn the ignition switch to LOCK.

304Section 4 Service Caution & NoticeI. Service CautionRefrigerant Treatment
•During the treatment, the operator shall be careful not to inhale A/C refrigerant or lubricant vapor. Long-
term exposure to the A/C environment will cause the operator's eye, nose and throat liable to stimulation.
In addition, based on the consideration on the environment influence, when discharging the HFC-134a
from the A/C system, we suggest using the recyclable and rechargeable devices. If sudden system fault
occurs, it is recommended to place the device on a ventilated place before starting service.
•For HFC-134a service equipment, it is recommended not to perform the pressurization check or leakage
inspection. If these mixture combust, it may result in severe human injury or property loss.
•Please be noticed not to let the refrigerant leak near the spark or other hot objects. If the refrigerant gas
contacts the spark or similar heat source (e.g. cigarette or heater), it may generate poisonous gas. The
refrigerant is extremely liable to leakage during the transportation. In this case, please eliminate or remove
the heat source mentioned above and keep good ventilation.
•It is very dangerous to handle the liquid refrigerant. Only a drop of refrigerant can result in local frostbite
on skin if dropped on the skin of the operator. Therefore, it is specified that the operator shall always
wear glove and eye protection during the handling of the liquid refrigerant. If liquid refrigerant gets in
your eyes or on your skin, Wash the area with much cool water. Go immediately to hospital for professional
treatment.
Refrigerant Preservation
• Refrigerant preservation container is a high pressure resistant equipment. If it is put in hot treatment, the
explosion may arise, and the resulting metal fragments and the splashed liquid refrigerant will result in
severe human injury. It is recommended to preserve the refrigerant below 40°C.II. Service NoticeInsufficient Refrigerant Handling
•If the refrigerant is founded to be insufficient during the fault diagnosis, it is recommended not to add
refrigerant because of the following facts: the pressure readings indicated by different pressure gauge
are different, thus you will be unable to determine the exact amount of the refrigerant to be added, and
excessive or insufficient refrigerant may cause a series of chained negative effects such as damaged
refrigerant circulation parts or deteriorated refrigeration effect. Therefore, if the refrigerant is found to
be insufficient, it is recommended to drain the refrigerant from the refrigerant circulation pipeline and fill
specified amount of the refrigerant.
Compressor Oil Handling
•For this type of vehicle, it is recommended to use SW-100 type compressor oil. Use of PAG compressor
oil other than the SW-100 type may cause the A/C compressor to be damaged.
•During the operation, please be noticed not to splash the SW-100 type compressor oil onto the vehicle
surface. Therefore, if this happens, please wipe it off immediately, otherwise the compressor oil will
damage the paint on the vehicle surface.
