6.6.6 Diagnostic Information and Procedures
6.6.6.1 Diagnosis Description
Read DTC codes through the vehicle data-link connector (DLC data-link connector). Use ABS control module data table, through
reading scan tool displayed data, to read the switches and sensors function without removing any component. Reading the data is
the first diagnostic step and is also one of the ways to reduce diagnostic time.
6.6.6.2 Visual Inspection
–
Confirm Fault Symptom
In the diagnostic process, the most difficult situation is that no symptoms appear. In this case, you must thoroughly analyze the
described malfunction. and then simulate the malfunction occurring conditions and circumstances. Even for a very experienced
technician, if carry out the diagnostic without verify the malfunctions first, it is possible to ignore a number of important things,
and make wrong judgment. This will cause the diagnostic can not continue.
–
Check the easy to access system components to identify whether there is a significant damage or a potential malfunction.
–
Connectors connection and vibration should be thoroughly examined. If possible, for vibrations caused malfunction, it is
recommended to use the vibration method.
1. With a finger, gently shake the sensor that may be faulty and check for malfunction.
2. Gently shake the sensor in the vertical and horizontal directions.
3. Gently shake the sensor wiring harness in the vertical and horizontal directions.

6.6.6.4 Scan Tool and The Vehicle Can Not Communicate
Connect scan tool to the data-link connector (DLC data-link connector), turn the ignition switch to ON, operate the scan tool, if the
display shows the communication error message, then the vehicle or the scan tool has a malfunction.
–
If the scan tool connected with another vehicle shows normal, then check the original vehicle DLC.
–
If the scan tool is still unable to establish communication, then the problem may be in the scan tool, for the specific circumstances.
Refer to
.
6.6.6.5 Fault Symptom Table
If the scan tool shows the normal codes, but the fault still exists, check the circuit whether there are various fault symptoms according
to sequence in the following table, and then refer to the appropriate maintenance program to fix the fault.
