CIRCUIT DIAGRAMS - Tension-reducer Type Seat Belt Circuit
OPERATION
If the driver fastens the seat belt with the ignition switch placed in the "ON" position, the seat belt
switch in the seat belt buckle is turned "ON" to operate the seat belt solenoid in the retractor.
This will reduce the seat belt rewinding torqe to minimize a sense of oppression given by the belt.
Owing to the timer function of the ETACS unit, the seat belt solenoid is kept in operation for 30 seconds
l
after turning off the ignition switch, with due consideration to elimination of the sudden rise in a sense
of oppression caused by the belt immediately after the ignition switch is turned off.
