413-01 Instrument Cluster: Description And Operation (page 5 of 17)

 

WARNING INDICATORS 

The warning indicators are located in various positions in the instrument cluster. The warning indicators can be split into 
two groups; self controlled and externally controlled. 
 
Self controlled warning indicators are dependent on software logic within the instrument pack for activation. The pack 
software controls the indicator check illumination at ignition on and all indicators whose operation is controlled by the 
instrument cluster, the low fuel level warning indicator for example. 
 
Externally controlled indicators are supplied with current from another system controlling module or illuminated by the 
instrument cluster on receipt of a bus message from another subsystem module. 
 
Some indicators are activated by an external subsystem module but the instrument cluster contains the control logic. 
These indicators are shown in the following table as being both self and externally controlled. 
 
The following table shows the available indicators and indicates if they are subject to an indicator check at ignition on and 
if they are self or externally controlled.
