Normal Operation
The safety belt warning indicator is controlled by the instrument cluster based upon the safety belt status received from the restraint control module (RCM). When the driver safety belt is unbuckled, the safety belt switch closes, providing a ground signal to the RCM through circuit 85 (BN/LB). When the driver safety belt is buckled, the safety belt switch opens, removing the ground path to the RCM. The RCM provides a ground to the instrument cluster through circuit 1390 (DB) when the safety belt switch is closed (unbuckled).

Possible Causes
- circuit 1390 (DB) open, short to ground or short to voltage
- RCM
- instrument cluster
