MAZDA RADAR CRUISE CONTROL (MRCC) WARNING LIGHT/INDICATOR LIGHT [MAZDA RADAR CRUISE CONTROL (MRCC) SYSTEM]

id0120g0000800

Purpose

MRCC indicator light (green)

•  The MRCC indicator light (green) notifies the driver as to whether the MRCC system is operating and in constant speed control mode or headway control mode.

MRCC warning light (amber)

•  The MRCC warning light (amber) warns the driver that a malfunction is occurring in the MRCC system.

Function

MRCC indicator light (green)

•  The instrument cluster turns the MRCC indicator light (green) on based on the system conditions display request signal sent via CAN communication from the vehicle control module (V/C-module).

MRCC warning light (amber)

•  The instrument cluster flashes the MRCC warning light (amber) based on the malfunction indication request signal sent via CAN communication from the vehicle control module (V/C-module).

•  The flash pattern of the MRCC warning light is as indicated in the table.

Operation

MRCC indicator light (green)

1.  The instrument cluster receives (1) the system conditions display request signal from the vehicle control module (V/C-module) via the CAN signal.

2.  The instrument cluster turns the transistor on (2) based on the system conditions display request signal.

3.  When the transistor turns on, a ground circuit with the MRCC indicator light (green) is established, and the MRCC indicator light (green) turns on (3).

MRCC warning light (amber)

1.  The instrument cluster receives (1) the system conditions display request signal from the vehicle control module (V/C-module) via the CAN signal.

2.  The instrument cluster turns the transistor on (2) intermittently based on the system malfunction indication request signal.

3.  When the transistor turns on intermittently, a ground circuit with the MRCC warning light (amber) is established intermittently, and the MRCC warning light (amber) flashes (3).
