DIAGNOSTICS SUPPLEMENTAL RESTRAINT SYSTEM
DI−271
1996 LAND CRUISER (RM451U)
DTC Normal Source Voltage Drop
CIRCUIT DESCRIPTION
The SRS is equipped with a voltage −increase circuit (DC−DC converter) in the airbag sensor assembly in
case the source voltage drops.
When the battery voltage drops, the voltage −increase circuit (DC−DC converter) functions to increase the
voltage of the SRS to normal voltage.
The diagnosis system malfunction display for this circuit is different to other circuits −when the SRS warning
light remains lit up and the DTC is a normal code, source voltage drop is ind\
icated.
Malfunction in this circuit is not recorded in the airbag sensor assembly, and the source voltage returns to
normal, the SRS warning light automatically goes off.
