WARNING: This page is about a different car, the 2013 Land Rover LR4, 2012 Land Rover LR4, 2011 Land Rover LR4, and 2010 Land Rover LR4. However, it is still accessible from the selected car via links, so may be relevant.

On the low line instrument cluster, the HDC warning indicator is an amber colored indicator located between the tachometer and the speedometer. On vehicles with the high line instrument cluster, the HDC warning indicator consists of a message in the message center.

On the low line instrument cluster the HDC warning indicator is continuously illuminated if there is a fault that affects the HDC function, and flashed at 2 Hz if the HDC function is temporarily unavailable because of brake overheat.

On the high line instrument cluster, appropriate messages are displayed in the message center if there is a fault that affects the HDC function, or if the HDC function is temporarily unavailable because of brake overheat. Refer to Information and Message Center article.

Operation of the HDC warning indicator is controlled by a high speed controller area network (CAN) bus message from the anti-lock brake system (ABS) module to the instrument cluster.

On the low line instrument cluster, when the ignition switch is first turned to position II, the HDC warning indicator illuminates for approximately 3 seconds as a bulb check.
