Circuit Description
When the ignition switch is turned “ON”, the SRS
control unit will perform tests to diagnose critical
malfunctions within itself. Upon passing these tests,
“Ignition 1”, and pretensioner loop voltages are
measured to ensure they are within their respective
normal voltage ranges.
The SRS control unit monitors the voltages at “Driver
Pretensioner Low” terminal “7” and “Passenger
Pretensioner Low” terminal “10” to detect short to
ground/+B in the pretensioner assembly circuits.
DTC Will Set When
“Ignition 1" is in the normal operating voltage range.
The voltage at “Passenger Pretensioner Low " is below
a specified value,
DTC B0033 will set.
