11.14.3 System operating principle 

11.14.3.1 Warning lamp control 

When starting the ignition switch in position ON at every turn, the multifunctional instrument 
inspects the warning lamp by itself, and the self-check process lasts for 3s; and when the warning 
lamp circuit faults or receives a signal of compelling to turn on the fault warning lamp, turn on the 
fault lamp to remind the driver. 

The following warning lamps in the multifunctional instrument are directly controlled by 
hardware as follows: 

– 

Sub-safety belt unsecured warning lamp 

– Tire-pressure 

warning lamp

11.14.7 Diagnostic information and procedures 

11.14.7.1 Diagnostic Information and procedures 

After being familiar with the system function and the operation content and then start the system 
diagnosis, so that it is conducive to the determination of the correct steps of fault diagnosis in the 
event of a failure; what's more, it is further conducive to determining whether the condition 
described by the customer belongs to the normal operation. 

11.14.7.1 Diagnostic information and steps 

– 

Inspect the after-sales optional device which may affect the normal operation of 
multi-functional instrument. 

– 

Inspect components easy to access system to identify whether there is a significant damage 
that may lead to the fault. 

– 

Inspect whether the system of each instrument displaying information is in normal condition.
