RESTRAINT CONTROL SYSTEM
9J1–20
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the malfunction is in
the SDM.
3. This test verifies proper connection of the yellow
2–pin connector.
4. This test cheeks for proper contact and/or corrosion
of the shorting clip in the yellow 2–pin connector
terminals.
5. The test checks for a malfunctioning passenger air
bag assembly.
6. This test determines whether there is an open in the
wiring.
Diagnostic Aids:
An intermittent condition is likely to be caused by a poor
connection at the passenger air bag assembly harness
connector terminals “1” and “2,” SDM terminals “15” and
“16,” or an open in CKT IB07–YEL/GRN and
IB08–YEL/RED.
DTC 17 Passenger Deployment Loop Open
Step Action Yes No
1 Was the “SRS Diagnostic System Check” performed?
Go to Step 2
Go to the “SRS
Diagnostic
System Check.”
2 1. When measurements are requested in this chart use J–39200
DVM with correct terminal adapter from J–35616–A.
2. Using scan tool data list function, read and record the
passenger differential voltage.
Is passenger differential voltage. more than 4.0 volts?
Go to Step 3 Go to Chart A .
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?
Go to Step 4
Seat passenger
air bag assembly
yellow 2–pin
connector
properly.
Go to Step 7
4 1. Disconnect and inspect the passenger air bag assembly
yellow 2–pin connector located behind the glove box
assembly.
2. If OK, reconnected the passenger air bag assembly yellow
2–pin connector.
3. Ignition switch “ON.”
Is DTC 17 current?
Go to Step 5
Ignition switch
“OFF.”
Go to Step 7
5 1. Ignition switch “OFF.”
2. Disconnect SRS coil and passenger air bag assembly yellow
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 17 current?
Go to Step 6
Ignition switch
“OFF.”
Replace the
passenger air
bag assembly.
Go to Step 7
6 1. Ignition switch “OFF.”
2. There has been an open circuit in 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?
Replace SRS
harness.
Go to Step 7
Go to Chart A .
7 1. Reconnect all components ensure all component are properly
mounted.
2. Clear diagnostic trouble codes.
Was this step finished?
Repeat the “SRS
Diagnostic
System Check.”
