Control lamps (Discovery 3)

The following anti-lock braking and traction control system indicator lights are located on the instrument panel:

ABS warning light

ABS warning light (anti-lock braking system) yellow color is located between the coolant temperature gauge and the fuel gauge.

ABS warning light (anti-lock braking system) illuminates continuously in the event of a fault affecting the operation of the ABS (anti-lock braking system) or leading to the disabling of the ABS function (anti-lock braking system).

To control the ABS warning light (anti-lock braking system) signals transmitted via the high-speed CAN bus are used (controller network) from ABS module (anti-lock braking system) in the instrument panel.

When the ignition key is first turned to position II, the ABS warning lamp (anti-lock braking system) turns on for approximately 3 seconds to check. If the ABS module memory (anti-lock braking system) fault code stored, ABS warning light (anti-lock braking system) will turn off for 0.5 s 0.5 s after the start of the lamp check. If a fault during the previous ignition cycle caused the ABS warning lamp to come on (anti-lock braking system), ABS warning light (anti-lock braking system) will remain on after the next lamp check even if the fault has been corrected and the fault code has been cleared from the ABS module. (anti-lock braking system); aBS warning light (anti-lock braking system) remains on until the vehicle speed reaches 15-20 km/h.

Brake system warning light

The brake system indicator light has two colors and is located on the coolant gauge.; the lamp lights up yellow when there is a fault with the EBA (emergency braking assistance system) and red light for EBD faults (electronic Brakeforce Distribution). The brake system warning light also provides warnings for the following events:

• Low brake fluid level (glows red). For more information, please refer to Hydraulic Brake Actuation (206-06)
• Brake pad wear (glows yellow). For more information, please refer to Rear Disc Brake (206-04)

The brake system warning lamp is controlled using signals transmitted via the high-speed CAN bus. (controller network) from ABS module (anti-lock braking system) in the instrument panel.

When the ignition key is first turned to position II, the brake system indicator lamp lights up yellow for 1.5 seconds and lights up red for 1.5 seconds for checking.

DSC indicator light

The DSC indicator lamp lights up yellow and is located on the tachometer.

When the DSC or ETC function is active, the DSC indicator lamp flashes at a frequency of 2 Hz. If the DSC function is switched off, or if a fault causes the DSC or ETC function to be switched off, the DSC indicator lamp lights continuously. If the DSC function is switched off and the vehicle has a high-level instrument cluster, a message is also displayed informing you that the DSC is switched off. For more information, refer to the Information and Message Center (413-08).

The DSC control arm is controlled using signals transmitted via the high-speed CAN bus. (controller network) from ABS module (anti-lock braking system) in the instrument panel.



When the ignition key is first turned to position II, the DSC indicator lamp comes on for approximately 3 seconds for testing. If a malfunction during the previous ignition cycle caused the DSC indicator lamp to come on, the DSC indicator lamp will remain illuminated after the next bulb check, even if the malfunction has been corrected and the DTC has been cleared from the ABS module. (anti-lock braking system); the DSC indicator lamp may remain on during vehicle operation due to additional checks of the relevant signals being performed.

HDC Status Indicator Light

The green HDC status indicator light is located on the tachometer.

The HDC status indicator light illuminates continuously when the HDC function is enabled and the vehicle condition meets the HDC operating conditions.; if the vehicle status does not meet the HDC enable parameters, the HDC status indicator lamp flashes at a frequency of 2 Hz.

The HDC status indicator lamp is controlled using signals transmitted via the high-speed CAN bus. (controller network) from ABS module (anti-lock braking system) in the instrument panel.

HDC Malfunction Indicator Lamp

On the low-level instrument cluster, the HDC malfunction indicator lamp is yellow and is located between the tachometer and speedometer. On vehicles with a high-level instrument cluster, the HDC malfunction indicator lamp functions as a message displayed in the message center.

On the low-level instrument cluster, the HDC malfunction indicator lamp lights continuously if there is a malfunction affecting the HDC function, and flashes at a frequency of 2 Hz if the HDC function is temporarily unavailable due to brake overheating.



In the high-level instrument cluster, appropriate messages are displayed in the message center display in the event of a fault affecting the HDC function and if the HDC function is temporarily unavailable due to brake overheating. For further information, refer to the Information and Message Center (413-08).

The HDC malfunction indicator lamp is controlled using signals transmitted via the high-speed CAN bus. (controller network) from ABS module (anti-lock braking system) in the instrument panel.

On vehicles with a low level instrument cluster, when the ignition key is first turned to position II, the HDC malfunction indicator lamp comes on for approximately 3 seconds for verification.
