DTC 22 Driver Deployment Loop Resistance Low
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 driver
deployment loop resistance.
Is driver resist. less than 1.9 ohms?
3 1. Ignition switch "OFF."
2. Make sure the SRS coil assembly yellow 2–pin connector
located at the base of steering column is seated properly.
Is the 2–pin connector connected properly?
4 1. Disconnect and inspect the SRS coil assembly yellow 2–pin

appropriate adapter to SRS coil and passenger air bag
assembly harness connectors.
4. Ignition switch "ON."
Is DTC 22 current?
6 1. Ignition switch "OFF."
2. There has been a decrease in the total circuit resistance of the
driver deployment loop.
3. Use the high resolution ohmmeter mode of the DVM while
checking CKTs IB05–YEL and IB06–YEL/BLK, and SDM
connector terminal "3" and "4" to locate the root cause.
Was a fault found?
7 1. Ignition switch "OFF."
2. Disconnect SRS driver / passenger load tool from SRS coil
assembly harness connector.
