be available. 
 
During the bulb check, if the indicator comes on for 0.5 second, then goes off for 0.5 second and is then illuminated for 
the remaining 2 seconds of the bulb check, this indicates that faults are stored in the ABS module memory. 
 
If the indicator was illuminated due to a sensor fault, the indicator will remain illuminated at the next ignition cycle, even if 
the fault is rectified. When the vehicle is driven above a speed of 20 km/h (12.5 mph) the indicator will be extinguished. 
This allows the ABS module to perform a thorough check of the system and to establish that the output from the replaced 
sensor is correct. 
 
17. Cruise Control Indicator  
 
The cruise control indicator is controlled by the ECM and the instrument cluster on receipt of CAN signals from the ECM. 
When the cruise control is selected on, the indicator is illuminated providing that cruise has been resumed and is not 
within 8 km/h (5 mph) of the set speed or cruise is on and the vehicle speed is within 8 km/h (5 mph). 
 
18. Adaptive Front Lighting System (AFS) Indicator  
 
The AFS indicator is controlled by the AFS control module and the instrument cluster software on receipt of CAN signals 
from the control module. The indicator is illuminated in an amber color for a 3 second bulb check when the ignition is 
moved to position II. 
 
The AFS indicator displays AFS system failures to the driver. If a failure occurs, the indicator will illuminate continuously 
until the fault is rectified. 
 
19 and 36. Park Brake Fault Indicator  
 
The park brake fault indicator is controlled by the instrument cluster software on receipt of CAN signals from the 
Electronic Park Brake (EPB) control module. The indicator is illuminated in an amber color for 3 second for a bulb check 
when the ignition is moved to position II. If a fault occurs in the EPB system occurs, the EPB control module requests 
illumination of the indicator which remains illuminated until the fault is rectified. 
 
20 and 37. Park Brake Warning Indicator  
 
The park brake warning indicator is controlled by the instrument cluster software on receipt of CAN signals from the 
Electronic Park Brake (EPB) control module. The indicator is illuminated in a red color when the park brake is applied. If 
the ignition is moved to the off position, the indicator remains illuminated for 3 minutes. If a fault occurs which prevents 
park brake application the indicator flashes and the park brake fault indicator is also illuminated. 
 
21. Front Fog Lamps Indicator  
 
The front fog lamp indicator is controlled by the CJB which illuminates the indicator via a hardwired connection to the 
instrument cluster. The indicator is illuminated in a green color at all times when the front fog lamps are selected on and 
the ignition is in position II. 
 
22. Rear Fog Lamps Indicator  
 
The rear fog lamp indicator is controlled by the CJB which illuminates the indicator via a hardwired connection to the 
instrument cluster. The indicator is illuminated in an amber color at all times when the rear fog lamps are selected on and 
the ignition is in position II. 
 
23. Trailer Indicator  
 
The trailer indicator is controlled by the instrument cluster software on receipt of CAN signals on the medium speed CAN 
bus from the Central Junction Box (CJB). When a trailer is connected to the vehicle electrical system and the turn signal 
indicator switch is operated, the CJB transmits a signal to the instrument cluster to operate the trailer indicator. The 
instrument cluster software controls the flash rate of the indicator which flashes in a green color. The trailer indicator 
flashes slowly, accompanied simultaneously by a sound from the instrument cluster sounder, at the same rate as the turn 
signal indicators. 
 
24. Auxiliary Heating Indicator  
 
The auxiliary heater indicator is only illuminated for a bulb check for 3 seconds when the ignition is moved to position II.  
 
25. Engine Management System (EMS) Fault Indicator  
 
The EMS fault indicator is only available on low line instrument clusters. The indicator is controlled by the ECM and the 
instrument cluster software on receipt of CAN signals from the ECM. The indicator is illuminated in an amber color for
