2.11.7 Diagnostic Information and Procedures
2.11.7.1 Diagnosis Description
Refer to
Starting System Description and Operation
get familiar with the system functions and operation before start system
diagnostics, so that it will help to determine the correct diagnostic steps, more importantly, it will also help to determine whether the
customer described situation is normal.
2.11.7.2 Visual Inspection
1. Check whether there are after market equipment that may affect the starting, charging or ignition system operations.
2. Check the easy to access system components to identify whether there is obviously damage or potential fault.
3. Check whether the battery is installed correctly.
4. Test battery status. Battery voltage is not less than 11 V.
5. Check whether there is wire damage. check starter motor, starter solenoid switches, ignition switches and the battery. Check
whether all ground connections are reliable.
6. If the battery, wires and switches are normal, and motor functions are normal, remove and test the starter motor.
7. When the charging system works properly, turn the ignition switch to "ON" position, the charge indicator lamp will be on. The
lamp will be off after the engine starts running.
8. Check whether the generator is loose or improperly installed, as well as the drive belt tension is normal, whether there is the
possibility of slipping.
2.11.7.3 Starter Can Not Stop

Step 5
Ignition switch is at "ON" position, does relay 85 terminal have 12V voltage?
No
Replace the starter. Confirm whether the fault
has been fixed.
Yes
Step 6
Check starter relay terminal No.85 voltage
(a)
Turn the ignition switch to "OFF" position.
(b)
Disconnect the ignition switch wiring harness connector IP23.
(c)
Measure starter relay terminal No.85 voltage, whether there
is 12V voltage?
No
Replace the ignition switch.
Yes
Step 7
Circuit between the ignition switch wiring harness connector IP23 and starter relay terminal No.85 is short
to power supply. Repair the faulty part.
Next
Step 8
Diagnostic completed.
2.11.7.4 Engine Can Not Start
Prior to the implementation of this test procedure, it is necessary to check all the starting system fuses, so that it will help with quick
Diagnostic.
Step 1
Verify the fault.
Next
Step 2
Does the engine run?
No
Yes
Step 3
Does the engine run properly?
No
Yes
Step 4
Check ignition / fuel system. Refer to
Crankshaft rotates, but the engine can not start.
.
Step 5
Check the starter motor power supply.
Check the following:
(a)
Whether the battery capacity is normal, whether the starting
voltage is lower than 10.5V, otherwise recharge the battery.

Engine
(b)
Check the battery terminal connections for existence of loose
and corrosion.
(c)
Check the engine mechanical system for existence of
unusual noise. Check whether the cylinder compression
pressure is normal.
All normal?
No
Repair the faulty part.
Yes
Step 6
Replace the starter motor.
Step 7
Does the starter rotate?
Yes
Replace the starter motor.
No
Step 8
Does the starter motor electromagnetic switch work?
No
Yes
Step 9
Check whether the engine and drive belt system catching (engine catching, generator catching)?
Yes
Repair the catching parts.
No
Step 10
Check whether the resistance between the battery and the starter solenoid switch is too high?
Standard Resistance:<0.3 Ω
Is the resistance specified value?
No
Check and repair the cable, if necessary,
replace the cable.
Yes
Step 11
Check whether the resistance between the battery and the starter ground circuit is too high.
Standard Resistance:<1 Ω
Is the resistance specified value?
No
Check and repair the cable, if necessary,
replace the cable.
Yes
Step 12
Check whether the starter solenoid switch wiring harness connections is normal.
