8.2.7 Diagnostic information and procedures
8.2.7.1 Diagnosis descriptions
Refer to 8.2.2 Description and operation, get familiar with the system functions and operation before starting
system diagnosis, so that it will help to determine the correct diagnostic steps, more importantly, it will also help
to determine whether the situation described by the customer is normal.
8.2.7.2 Visual inspection
Inspect the after-sales optional device which may affect the performance of A/C system.
Inspect the parts and circuits of A/C system which are accessible and easy to be seen, to find out whether there is
any damage or possible cause to fault.
Inspect the pipelines which are accessible and easy to be seen, to find out whether there is any leakage of A/C
system.
