Indicator and warning signals | Function | ||
Yellow warning lamp | In the event of a fault in a CAN or K-line electronic system, the yellow warning lamp is actuated by the instrument according to the fault priority (0). | The warning lamp is also activated by the instrument in the event of a fault in Check Control mode. | |
Red warning lamp | In the event of a fault in a CAN or K-line electronic system, the red warning lamp is actuated by the instrument according to the fault priority (1 and 2). | The warning lamp is also activated by the instrument in the event of a fault in Check Control mode. | |
Engine oil level/engine oil pressure warning lamp (Check Control lamp under the display) | The signals are registered in the MR control module (A6) and transmitted over the engine CAN bus to the FR control module (A3). The signals are transmitted in a message over the vehicle CAN bus to the instrument. | The warning lamp is activated by the instrument. The engine oil level in liters or the engine oil pressure in bar is displayed on screen by the instrument. | |
Coolant level warning lamp (Check Control lamp under the display) | The signal is registered in the FR control module (A3) via the coolant level switch (B6) and is transmitted in a message over the vehicle CAN bus to the instrument (P2). | The warning lamp is activated by the instrument. | |
Air cleaner low pressure warning lamp (Check Control lamp under the display) | The signal is registered in the FR control module (A3) via the air cleaner low pressure switch (B7) and is transmitted in a message over the vehicle CAN bus to the instrument (P2). | The warning lamp is activated by the instrument. | |
Parking brake indicator lamp | The signal is registered in the FR control module (A3) via the parking brake switch (B5) and is transmitted in a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. | |
ASR indicator lamp | During ASR control the signal is transmitted by the ABS control module (A10, 4-channel ABS only) in a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. | |
EDC indicator lamp | 1. In the event of a fault in the engine control (MR) the MR control module (A6) transmits a message over the engine CAN bus to the FR control module (A3). The FR control module transmits this message over the vehicle CAN bus to the instrument (P2). 2. In the event of a fault in the drive control (FR) or on the engine CAN bus, the FR control module (A3) transmits a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. | |
ABS indicator lamp | In the event of a fault in the anti-lock brake system the ABS control module (A10, 4-channel ABS only) transmits a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. | |
Retarder indicator lamp | The retarder is actuated by the drive control (FR) control module (A3). When actuated, the FR control module transmits a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. | |
Charge warning lamp | The D+ control is performed by the FR control module (A3). If D+ control is not possible, the FR control module transmits a message over the vehicle CAN bus to the instrument (P2). | The warning lamp is activated by the instrument. | |
MSS (engine start/stop facility) indicator lamp | The engine start/stop facility (the engine is switched off automatically, e.g. when stopped at traffic signals, and restarted by actuation of the clutch) is activated or deactivated via the MSS switch in the FR control module (A3). When the MSS is actuated, the FR control module transmits a message over the vehicle CAN bus to the instrument (P2). | The indicator lamp is activated by the instrument. The MSS facility must be parameterized in the FR control module (A3). |
