2.5.7 Diagnostic Information and Procedures
2.5.7.1 Diagnosis Description
Refer to
2.5.2.1
Description and Operation
get familiar with the system functions and operations then start system diagnostics, so
that it will help with the correct diagnostic steps, more importantly, it will also help to determine whether the customer described the
situation is normal.
2.5.7.2 Visual Inspection
–
Check installed after market equipment that may affect the engine anti-theft system operation.
–
Check the easy to access system components to identify whether there is a significant damage that may lead to the fault.
–
If the system shows the engine is locked, prior to the fault diagnostic check and confirm whether the ignition key completed self
learn, otherwise carry out the ignition key learn process. Refer to the
2.5.7.7
