BLINDSPOT Monitoring Control Module

Blindspot monitoring uses a cross over radar pattern to the rear of the vehicle and is used to determine actual moving vehicles eliminating any stationary roadside objects.

The system monitors an area extending from the exterior mirrors rearwards, to approximately 6 meters (20 feet) behind the rear wheels, and up to 2.5 meters (8.2 feet) from the side of the vehicle.

The driver will be alerted, with a solid warning light emitting diode (LED) in the relevant door mirror.

G11701828

The system will warn the driver of the presence of vehicles in a defined closing vehicle warning zone, which poses a hazard to the driver if a lane change maneuver is made.

The driver will be notified of the hazard by flashing the existing blindspot icon in the relevant door mirror.

NOTE: If an overtaking vehicle is detected on both sides of the vehicle simultaneously, the warning alert icons in both mirrors will illuminate.

The Light Emitting Diodes (LED) are located towards the outside extremity of the mirror face, within the peripheral view of the driver but not in any area of the mirror where they could obscure or distract from the image.

ITEM DESCRIPTION
1 Warning Alert Icon
2 System Status Warning Indicator

The LED lighting alerts are as follows:

The system has operating limitations and is automatically turned off under certain operating conditions. During these operating conditions the amber status LED is permanently lit.

The system operating limitations are as follows:

NOTE: If Reverse Traffic Detection (RTD) is fitted the standby dot will be off when reverse is selected indicating that the system is active. If RTD is not fitted then the standby dot will be on indicating that the system is not active.

If either of the radar signals generated by the Blindspot Monitoring Control Module (BMCM) are blocked or distorted by for example:

the system may detect this and be disabled with the amber status LED permanently lit together with a 'blindspot monitoring blocked' message displayed in the Instrument Cluster (IC) message center.

The system is disabled until the blockage is cleared.

If there is a fault in the system the amber status LED is permanently lit and a 'blindspot monitoring not available' message displayed in the IC message center. The system is disabled until the fault is rectified.

System fault and blockage warnings are as follows:

If there is a failure in the communication network and the warning LED cannot be displayed in the mirror, a failure message will be displayed in the IC message center.

When any faults are present in the system, Diagnostic Trouble Codes (DTC) are stored in both Blindspot Monitoring Control Modules (BMCM) appropriate to each module. Replacement of modules requires the modules to be configured using the Land Rover approved diagnostic equipment.

Calibration of the modules using the Land Rover approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
