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
