DTC 15 Passenger Deployment Loop Resistance High
Step
1 Was the "SRS Diagnostic System Check" performed?
2 1. When measurements are requested in this chart use J–39200
DVM with correct terminal adapter from J–35616–A.
2. Use scan tool data list function, read and record the passenger
deployment loop resistance.
Is passenger resist more than 2.9 ohms?
3 1. Ignition switch "OFF."
2. Make sure the passenger air bag assembly yellow 2–pin
connector located behind the glove box assembly is seated
properly.
Is the yellow 2–pin connector connected properly?
4 1. Disconnect and inspect the passenger air bag assembly
yellow 2–pin connector located behind the glove box

5 1. Ignition switch "OFF."
2. Disconnect SRS coil and passenger air bag 2–pin connectors
located at the base of the steering column and behind the
glove box assembly.
3. Connect J–41433 SRS driver / passenger load tool and
appropriate adapters to SRS coil and passenger air bag
assembly harness connectors.
4. Ignition switch "ON."
Is DTC 15 current?
6 1. Ignition switch "OFF."
2. There has been an increase in the total circuit resistance of the
passenger inflator deployment loop.
3. Use the high resolution ohmmeter mode of the DVM while
checking CKTs IB07–YEL/GRN and IB08–YEL/RED, and
SDM connector terminal "15" and "16" to locate the root cause.
Was a fault found?
7 1. Reconnect all components ensure all component are properly
