# Service bulletin 2070998/1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- NHTSA id: 10240268
- Published by NHTSA: 2023\-08\-03

- NHTSA component: SEAT BELTS; ELECTRICAL SYSTEM

## NHTSA's summary

Rear seatbelt \- Incorrect buckle status within the DIP \- Bentayga Series. Customer statement: Incorrect rear seatbelt buckle status shown within the DIP Workshop findings: Although there is no occupant evident within the rear seats \(2nd row\) the rear seat is shown as occupied \(Figure 1\). Technical background: There is no specific DTC evident for the scenario described. The issue described is evident as the rear seat belt buckles are not resistor coded The system uses a non\-resistor coded buckle strategy \(zero\-infinity or open\-closed buckle\) for the rear seats. In correct operation, a fastened seatbelt is open circuit and an un\-fastened seatbelt is closed circuit If harness damage is present or an electrical connector joint is not properly engaged, an unintended open circuit occurs. This will give an incorrect buckle status reading within the DIP The advice within this TPI should be referred to first before conducting any further diagnosis or disassembly of the vehicles interior Previous assembly/disassembly may have caused an unintentional open circuit when operatives have been working on or around the rear seat belt assemblies
