Land Rover Defender: Seatbelt System - Operation

SEATBELT REMINDER

NOTE: The warning indicator is displayed each time there is a status change. For example, a seatbelt is unfastened or a door is opened and then closed.

The seatbelt warning indicator and a warning chime come on when the driver seatbelt, or the seatbelt of an occupied passenger seat, is not fastened. The indicator goes off when the unfastened seatbelt is fastened.

The RCM provides driver and passenger buckle status signals on FlexRay which are provided to the IPC through the BCM/ GWM. The BCM/ GWM provides the first row middle seat buckle status (If equipped) on HS CAN body system bus which are provided to the IPC through the BCM/ GWM.

NOTE: For front row middle seat provides the BCM/ GWM with the occupancy using an Occupant Detection Sensor .

The front outer passenger seat occupancy status is provide by:

• A hardwired input from the occupant detection sensor, except NAS vehicles.
• A Local Interconnect Network (LIN) systems bus message from the OCS to the RCM on NAS vehicles only.

BELTMINDER SYSTEM

NOTES:

• Although not advisable, it is possible to disable the beltminder system using Jaguar Land Rover (JLR) approved diagnostic equipment.
• When a heavy object is placed on a passenger seat, it may activates the beltminder feature. The feature recommends that any objects placed on that seat are secured using the seatbelt.

Where equipped, the beltminder system augments the seatbelt reminder. At vehicle speeds above 20 km/h (12 mph), if the seatbelt has not been fastened, the beltminder system activates an intermittent warning chime. At the same time the beltminder system flashes the seatbelt warning indicator and displays a warning message indicating which second row seatbelt triggered the warning.

When the beltminder is triggered, the IPC generates the following warnings repeated for 10 seconds:

• Flashes the seatbelt warning indicator at 2 Hz
• Triggers the audible chime.

After 10 seconds the seatbelt warning indicator changes from flashing to continuously illuminated for 10 seconds.

While the trigger conditions still exist, the warnings are repeated every 20 seconds until one of the following occurs:

• 190 seconds has elapsed from when the warnings were first triggered.
• The seatbelt of each occupied front row seat is fastened.
• In Power Mode 0 (ignition OFF)
• In REVERSE.

NOTE: On NAS market vehicles when the driver seatbelt is not fastened, the warning indicator and audible chime triggers for 6 seconds. After the 6 seconds, the warning indicator remains visible for 60 seconds.

When stationary a single audible warning indicates that the second row seatbelt is not fastened.

Above 20 km/h (12 mph) the audible warning is triggered for 10 seconds, then switches off for 10 seconds. This cycle is repeated for 60 seconds. The audible warning will cease when a rear door is opened when stationary (or front door in 3 seat vehicle) if:

• The vehicle is put in REVERSE
• A rear belt is buckled
• In Power Mode 0 (ignition OFF).

VISUAL BELTMINDER

1. Indicator - Second row
2. Indicator - Third row

A graphic in the IPC indicates which of the second row and third row seatbelts are fastened at the start of a journey.

The graphic indicates when a seatbelt is fastened or unfastened during a journey. Each seating position is represented by a passenger icon.

The color of passenger icon indicates the seatbelt status:

• No color - Seatbelt not fastened.
• Green - Seatbelt fastened.
• Red - Seatbelt status changed from fastened to unfastened.

When the seatbelt of an occupied seat is not fastened or is unfastened during a trip, an audible warning sounds.

DIAGNOSTICS

The RCM records any Diagnostic Trouble Code (DTC)s and related data. Read the DTCs and related data with the JLR approved diagnostic equipment.

The JLR approved diagnostic equipment enables certain components to be activated and also live data to be read.
