Land Rover Defender: Warning Devices - Description

SIDE OBSTACLE DETECTION CONTROL MODULE

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

1. SODR
2. SODL

There are 2 side obstacle detection control modules installed in the corner of the rear bumper, 1 on each side.

The SODR has the following connections:

• Power
• Ground
• High Speed (HS) Controller Area Network (CAN) Underbody (UN) systems bus
• Private CAN bus.

The SODL does not have a HS CAN UN systems bus connection.

The SODR and SODL exchange data on the private CAN bus. The SODR communicates the data on the HS CAN UN systems bus to the BCM/ GWM.

The following systems are hosted in SODL/ SODR:

• BSM
  • The blind spot monitoring system monitors an area adjacent to the vehicle.
• Reverse Traffic Detection
  • The rear traffic detection feature assists the driver when carrying out a reversing maneuver.
• Rear protection monitor.
  • The rear protection monitor system helps identify any potential collision risks from the rear of the vehicle.

They are incorporated in each of the SODL/ SODR and are connected by a Private CAN bus to exchange information.

Each SODL/ SODR does an auto-alignment self-check every time when in use. The auto-alignment self-check can take up to an hour in some environments. However the BSM continues to operate as normal.

The SODR receives vehicle speed on the HS CAN UN systems bus.

DRIVER ASSISTANCE DOMAIN CONTROLLER

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

The DADC 'A' is not available on L663 20MY.

1. DADC 'A'
2. DADC 'B'

The DADC is located behind the right of the instrument panel.

The following features are hosted in DADC:

• LKA
• Blind Spot Assist.
• Speed Limiter
• Adaptive Speed Limiter
• Cruise Control
• Adaptive Cruise Control
• Traffic Sign Recognition and many others.

IMAGE PROCESSING MODULE 'A'

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

The IPMA is located above the rear view mirror.

The IPMA has 1 forward facing camera. The IPMA receives an ignition supply from the Engine Junction Box (EJB).

Information can be exchanged from the IPMA through an ETHERNET connection to the GWM which then re-directs the necessary signals to each ECU. The IPMA is also connected to the HS CAN UN system from which it receives necessary information to compute object detection correctly.

NEAR FIELD SENSING MODULE AND NEAR FIELD SENSING MODULE 'B'

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

The NFSM 'B' is not available on L663 20MY.

1. NFSM
2. NFSM 'B'

The NFSM/ NFSM 'B' is located below the instrument panel. The NFSM is equipped on vehicles with a proximity camera system, the NFSM 'B' is equipped on vehicles with a rear view camera system.

REAR VIEW CAMERA

NOTE: Vehicle with 5 doors is shown, vehicle with 3 doors is similar.

The rear view camera is located in the center of the rear bumper, above the license plate.

CLEAR EXIT DETECTION SYSTEM INDICATOR

NOTE: RHD vehicle is shown, LHD vehicle is similar.

1. Traffic alert
2. Status LED

The CEDS indicator is located adjacent to the door inner handle.

The CEDS system does not inhibit the opening of the door.

The status LED illuminates when the CEDS system is active.

When a perceived threat approaches the host vehicle the amber traffic alert LED illuminates as a warning to the occupant. A perceived threat is a cyclist or other road users approaching from the rear of the vehicle.

DOOR MODULE

NOTES:

• The DDM is shown. The others are similar.
• RHD vehicle is shown, LHD vehicle is similar.

The door modules require a number of inputs to send the correct message to the CEDS:

• 'Backlight status'
• 'Child Lock Cmd (from the door latch)'
• 'Power Mode'
• 'Door Status'
• 'Alert' 'Left RED Alert/Right RED Alert'.

To assess the CEDS indicator and send the correct software message the door modules also requests the following software information from the CEDS indicator:

• 'CEDSHMIStatus'
• 'PartNo'
• 'PartNoBlkNo'.

The door modules then sends the correct software message to the CEDS indicator from the following messages:

• 'Status' ('StatusLED')
• 'Traffic' ('TrafficLED')
• 'Backlight' ('BacklightStatus').

DOOR AJAR SWITCH

The following components incorporate an ajar switch:

• Each door latch
• The left hood latch
• Tailgate latch.

The door ajar switch sends the door status message to the BCM/ GWM. The status message is then sent to the relevant door module. The each door module uses the information to either illuminate or extinguish the CEDS LEDs. If the door is still open, the LEDs remain illuminated.

TOUCHSCREEN

NOTE: RHD vehicle is shown, LHD vehicle is similar.

The TS is located in the center of the instrument panel.

The TS is controlled by the user using touch icons located in the screen image.
