158III. CUSTOMER FAULT ANALYSISNOTES:
1. When the troubleshooting analysis is underway, make sure to confirm the fault symptom correctly. Re-
move kinds of suppositions in order to make an exact judgment. In order to find out what on earth the fault is,
it is extremely important to ask customers about the fault symptoms and the conditions when faults occurred.
2. The 5 items below are the key points to analyze. Those faults that were considered irrelevant and the
repair history, etc are sometimes helpful. Therefore, try your best to collect relevant information, and find out
the relationship between the information you collected and the present information, in order to make refer-
ence in troubleshooting.
Key points of the Customer fault analysis:
1Vehicle model, system name
2Date, time, frequency fault occurs
3 Pavement conditions
4Running performance, driving and weather conditions
5Fault symptomIV. FAULT SYMPTOM AND DTCSNOTES:
1. The diagnosis system of the Free Cruiser possesses many features. The first important feature is the DTC
Checking. Input a fault from the ECU signal circuit in the form of code, and store it into the ECU memory.
The other feature is Input Signal Inspection. Inspect if the signals from different switches are correctly
inputted into the ECU. These features can quickly narrow the range of troubleshooting, to make an efficient
troubleshooting analysis. In the model of Free Cruiser, the systems below all possess the diagnosis feature.
1EFI system
2 ABS system
3Supplemental Restraint System (SRS)
2. When a DTC is checked, the very important point is: make sure if the fault shown by a DTC still exists, but
is normal now. In addition, when checking the fault symptom, you must check if there is direct relationship
between the fault shown by the DTC and the fault symptom. Therefore, the DTC should be checked before
and after confirming the fault symptom in order to confirm the present conditions. If you do not do so, it is
possible to make some unnecessary troubleshooting analysis on normal systems in some certain circumstances,
thus making it more difficult to locate the fault or repair according to the fault. So, a DTC check should be
done by a normal procedure.
3. The procedure below shows how to make a troubleshooting analysis by checking a DTC and how to make
efficient use of DTC check. Then carefully check the result, make a troubleshooting analysis of the DTC and
a troubleshooting analysis of the symptom.
1Inspect DTC
2Record and clear all DTCs
3Confirm fault symptom
1594Make a simulation test in a way of symptom simulation
5Inspect DTC
6Confirm symptomV. SYMPTOM SIMULATIONNOTES:
The most difficult conditions to handle in the fault troubleshooting are that the fault symptom dose not appear.
Under the circumstances, make sure first to make a comprehensive analysis to the fault described by the
customer, then to simulate an environment that is similar or the same with the conditions when the fault of the
customer's vehicle occurred. No matter how rich the experience of the technician is and how skillful he is, if
he make a fault troubleshooting analysis without confirm the fault symptom, it is inevitable for him to neglect
some important factors and incorrectly guess, which may cause barriers to repair. For example, if a fault
occurs only when the engine is cool or if a fault occurs only caused by a vibration from pavement and so on,
when the engine is checked in the hot or static state, it is no way to confirm. Because of vibration, high-
temperature or seeping water (Vapor) often causes some faults that are difficult to reappear. So, here are
some effective symptom simulation tests.
KEY POINTS OF SYMPTOM SIMULATION TEST:
In the symptom simulation test, no doubt it is important to confirm the fault symptom, but the fault position or
fault components must be also found out. So, before the test and the pre-inspection of connection, narrow the
range of the circuit where faults may occur according to the fault symptom. Then make a symptom simula-
tion test to see if the circuit measured is normal; the fault symptom is also verified at the same time.
1. Way of Vibration: When vibration may be the major cause of the fault.
For example:
(a) Use your hand to gently vibrate the sensor that is considered the cause of the fault, in order to check if it
is ineffective.
(b) Softly rock the connector and harness in horizontal and vertical direction.
Notes: Hard rock may cause the relay circuit open.
2. Way of Spraying Water: When rainy weather or wet environment may be the major cause of the fault.
(a) Spray water on the vehicle to check if the fault occurs.
NOTES:
yBe sure not to directly spray water into the engine compartment. Spray the water on the face of the
radiator to change the temperature and humidity indirectly.
yBe sure not to spray water onto electronic devices and controllers.
