RESTRAINT CONTROL SYSTEM
DTC 15 Passenger Deployment Loop Resistance High
D09RW002
Circuit Description:
When the ignition switch is turned “ON”, the 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. The
SDM then proceeds with the “Resistance Measurement
Test”. “Passenger Bag Low” terminal “16” is grounded
through a resister and the passenger current source
connected to “Passenger Bag High” terminal “15” allows a
known amount of current to flow. 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 CKTs IB07–YEL/GRN and IB08–YEL/RED
connector terminal contact.
DTC Will Set When:
The combined resistance of the passenger air bag
assembly, harness wiring CKTs IB07–YEL/GRN and
IB08–YEL/RED, and connector terminal contact is above
a specified value. This test is run once each ignition cycle
during the “Resistance Measurement Test” when:
1. No “higher priority faults” are detected during
“Turn–ON.”
2. “Ignition 1” voltage is in the specified value.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets a
diagnostic trouble code.
DTC Will Clear When:
The ignition switch is turned “OFF.”
