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.

2Record and clear all DTCs

272Chapter 8 MK-20 ABS SystemSection 1 ABS DiagnosisI. Check the ABS Warning Light1. Check the ABS Warning Light goes on as the following:
1Turn the ignition switch to ON, the ABS Warning Light goes on for about 1.7 seconds and then goes off.
2If the above condition is not satisfied, it indicates that there is a fault, please check the DTC.
3If the warning light does not light up at all, refer to the Non-DTC fault inspection table.II. The Reading of the information statusAfter connecting the scan meter, turn the ignition switch to¡°ON¡±, select the function menu item 01, press
OK to confirm, the screen will display the following information:
1. ECU drawing number and its version:
ABS MK20 IE
2. Code 01901III. Read and Clear the DTC1. After selecting the "02 Read DTC" in the function menu, it displays the total amount of the fault, if there
is no DTC, then it displays no DTC. Then, press OK button to proceed to next page to review the DTC
and its description. Generally, there is a P or O before the DTC, indicating that it is a Persistent fault or
Occasional fault. Persistent fault remains existing all the time, while the Occasional fault can be cleared
and is only able to reoccur during the driving.
Note:
The reading of the DTC can not be quitted middle way, you can return to the function menu only
after reading all the DTC.
Clear DTC
2. Select function menu item 05, press OK button to clear the DTC, if the DTC can not be cleared, it
indicates that the DTC represent exist all the time, if the saved DTC can be cleared, it indicates that it is
occasional fault can only be detected during the driving.

273IV. DTC Display Method
V. HCU DiagnosisUse the scan meter to diagnose the Hydraulic Control Unit (HCU), select the "3 HCU diagnosis" in the
options and perform the following procedures.
* Perform the above step 2 - 8 test for each wheel in the following order LF RF LR RR.
* If the result of some one of the above steps is different from the normal result, it indicates that the
corresponding element fails the normal operation, please check the corresponding element.
* You can use “ESC” button to end the test to return the function menu in any place in the screen where
there is “return” displayed to return to the function menu.Code Displa ye d
