DTC B1511 SEAT BELT BUCKLE SWITCH [DRIVER] OPEN OR SHORT TO BATTERY; DTC 
B1513 SEAT BELT BUCKLE SWITCH [PASSENGER] OPEN OR SHORT TO BATTERY 

DTC DESCRIPTION 

The Seat Belt Buckle Switch (BS) circuit consists of the SRSCM and two BS. The SRSCM sets above DTC (s) 
if it detects open or short to battery line on the BS circuit. This system decides whether the driver or passenger 
seat belt is buckled or not.
