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;

66f. The idle control valve is faulty;
g. The water temperature sensor is damaged;
h. The vacuum pressure sensor is damaged;
i. The air filter is blocked;
j. The injector leaks;
k. The compression pressure in the cylinder is too low;
l. The intake temperature sensor is damaged.
(3) Diagnosis and Troubleshooting
a. Check high pressure spark, check whether the high pressure spark on the ignition coil high pressure
bus and extension are OK, if the bus spark is week, replace the ignition coil, if the bus spark is OK
while the extension spark is too week, replace the ignition coil also; In addition, excessive spark
plug clearance will influence the starting feature, the clearance of the spark plug shall be adjusted
to normal value (0.8±0.1mm);
b. If there is low fuel pressure, check whether the battery voltage is OK, otherwise it shall be
troubleshot or replaced; check fuel pump check valve for leakage, check fuel filter and fuel pipe for
block, if there are leakage or block, replace or troubleshoot them;
c. If there is leakage for fuel pressure regulator, intake manifold is likely to be mixed with gasoline and
it is hard to start, troubleshoot or replace them;
d. Idle control valve can not be opened to maximum position due to mechanical wear, aging or control
circuit failure, the idle control valve shall be replaced and the control circuit failure shall be troubleshot;
e. If the water temperature sensor data is not accurate, it may cause small injection, check the water
temperature sensor based on the standard data and calibrate the data;
f. There is big time lag for intake pressure temperature sensor that makes it somewhat insensitive at
low speed and result in inaccurate injection, adjustment or replacement shall be made;
g. If the air cleaner filter is too dirty, the air flow resistance is excessively big, resulting in hard start,
as a result of it, the filter shall be replaced.
In a word, there are many factors causing the starting failure of the engine, analysis shall be made based on
the severe conditions of the faults. Generally speaking, check the ignition system first, then check intake
system, fuel system, control system, at last check the cylinder pressure, check the DTC before checking the
trouble. The diagnosis and troubleshooting procedures for starting failure of the engine are shown in (Figure
148).

83ECU microcomputer consists of microprocessor, memory, clock generator, timer, I/O interface and input
level A/D converter that are integrated in a large scale integrated circuit chip, that is SCM (Single Chip
Microcomputer).
1. Input level
The input signals from the sensor are pre-processed by the input level. The input signals are sent to protected
circuit first, sometimes through the signal converter and amplifier, and then sent to microcomputer.
The sensor signal is separated into switch type and analog type. Ignition on/off signal, camshaft position
signal, vehicle speed signal and A/C signal are switch type; Signals such as battery voltage, engine temperature,
intake temperature, airflow, intake manifold absolute pressure, throttle opening, excessive air coefficient,
knock, A/C refrigerant pressure are analog type. Analogy signal can only be processed by the digital micro-
computer after being converted into digital signal by A/D converter. Hence, data collection shall be made
first for analog signal, and the sampling shall be maintained also.
Speed and crankshaft position reference signal from the sensor is processed in a dedicated circuit to restrain
the interference pulse.
2. Microcomputer
The microcomputer of the engine electronic control unit is integrated in a single chip microcomputer, consist-
ing of the following:
(1) Microprocessor, microprocessor is also called as central processing unit (CPU), consisting of the following
three parts:
Arithmetic logic unit.
Register group.
Controller.
(2) System assembly, The data transferred among the internal sections of the single chip microcomputer
(SCM) is performed on the internal bus, while that between the SCM and other components is performed
on the external bus. The external bus is also called system bus. It is separated into data bus, address bus
and control bus.
(3) Memory, the memory is designed to store the binary data. The primary components of the memory are:
Memory.
Data register.
Address register, address decoder.
a. Memory controller
(4) A/D converter
(5) I/O interface.
(6) Clock generator.
(7) Timer
(8) CAPCOM unit.
(9) Watchdog timer.
(10) Interrupt system.

157Part III Electrical EquipmentChapter 1 SurveyThis part refers to the electrical repair of the Free Cruiser, and analyzes the faults from every system. Then
some practicable diagnosis procedure and repair ways are given.I. HAND-HELD TESTER1. Before the tester is used, a through reading of the Tester Operation Manual is commended.
2. Connect the tester to the diagnosis interface with a wire. Turn the ignition switch ON. At this time, if the
tester and ECU control system cannot communicate, the vehicle or the tester may have faults.
(1) Connect the tester lead wire to another vehicle. If the communication is normal, inspect the vehicle
diagnosis Busline or power supply circuit.
(2) If it still cannot communicate when connecting to the other vehicles, it may have faults on tester itself.
Consult the self-inspecting procedure described on the Tester Operation ManualII. HOW TO PROCEED WITH TROUBLESHOOTINGThe basic operation procedure for troubleshooting is as follows.
1. Customer fault analysis
(a) Ask the customer for the conditions and environment when faults happen.
2. Confirm the fault symptoms, and check the DTCs and storage data.
(a) Check the battery positive voltage (Voltage: 10 - 14V when the engine is stopped.)
(b) Inspect the harness, connector and fuse for open and short, etc. by their appearance.
(c) Warm up the engine temperature to the normal operation temperature.
(d) Confirm the fault symptoms and check the DTCs.
(e) Confirm the test procedure for the parts or systems that need checking.
3. Circuit or part inspection
4. Repair
5. Test for checking
(a) After the repair is completed, verify if the fault has been removed.
(If the fault has not appeared yet, a verifying test should be done under the same conditions and environment
when the fault first occurred.)
