Operation
The supply is taken from fuse 5 via the 29-pole red connector 152B and seat-belt warning lamp 72 to the driver's seat-belt switch 70. The switch connects the warning lamp to earth, and the warning lamp will thus light up. When the seat-belt buckle is inserted into the lock, the switch will open the circuit and the lamp will be extinguished.

Seat switch 69 is connected in series with seat-belt switch 71 on the co-driver's side. The seat switch will close when a load is applied to the seat. The warning lamp will thus light up only if a person is seated in the co-driver's seat and the seat belt is not fastened.

Fault-tracing hints
The seat-belt warning lamp will be operative when the ignition switch is in the drive position.

1. Check fuse 5 and check that the supply to it is live.
2. Check seat-belt warning lamp 72.
3. Check seat-belt switches 70 and 71, and seat switch 69.
4. Check the connectors, cable harnesses and earth connections.
