RESTRAINT CONTROL SYSTEM
DTC 17 Passenger Deployment Loop Open
D09RX002
Circuit Description:
When the ignition switch is turned “ON", the Sensing
and Diagnostic Module (SDM) will perform tests to
diagnose critical malfunctions within itself. Upon
passing these tests, “ignition 1", and deployment loop
voltages are measured to ensure they are within their
respective normal voltage ranges. During “Continuous
Monitoring" diagnostics, a fixed amount of current is
flowing in the deployment loop. This produces
proportional voltage drops in the loop. By monitoring
the voltage difference between “Passenger Bag High"
and “Passenger Bag Low", the SDM calculates the
combined resistance of the passenger air bag
assembly, harness wiring Circuits(CKTs) IB07–
YELLOW/GREEN and IB08– YELLOW/RED, and
connector terminal contact.
DTC Will Set When:
The voltage difference between “Passenger Bag High"
terminal “15" and “Passenger Bag Low" terminal “16" is
above or equal to a specified value for 500 milliseconds
during “Continuous Monitoring".
Action Taken:
SDM turns “ON" the “AIR BAG" warning lamp and sets
a diagnostic trouble code.
DTC Will Clear When:
The voltage difference between “Passenger Bag High"
terminal “15" and “Passenger Bag Low" terminal “16" is
below a specified value for 500 milliseconds during
“Continuous Monitoring".
