Air bag light flashing

My air bag flashing a code 34, not sure if there bad steering wheel clock-spring. Or wiring or a bad wiring. I checked online on this it tells me it a it clock-spring. Any help so I can troubleshoot this problem.
Do you
have the same problem?

SRS code 34: Driver Side Air Bag Circuit Low Resistance Or Shorted

I will include the OEM description below. Normally you see this code for a short in the wiring to the clock spring. The only way to test it is to remove the bag assembly and test the wiring for a short.

Normal Operation

The diagnostic monitor measures the resistance across pin 10 (Circuit 615, GY/W) and pin 11 (Circuit 614, GY/O) every time the ignition switch is turned to the ON position. Normal resistance across these circuits is between 1.5 and 2.0 ohms. This resistance comes from the air bag itself (approximately 1.0 ohms ) and the clock-spring winding's (0.3 to 0.4 ohms per winding, two winding's in all). If the resistance across these two circuits is less than 0.7 ohms, the diagnostic monitor will flash code 34 on the air bag lamp.

NOTE: The connectors for the air bag and the clock-spring have metal spring clips that act as shorting bars. These shorting bars are built into the plastic hard-shell connectors. The shorting bars are designed to short Circuits 614 and 615 together when the connectors are not mated. Do not attempt to remove the air bag shorting bar and measure the resistance of the air bag. The clock-spring shorting bar may be removed to measure the clock-spring resistance. Use extreme care when reinstalling the shorting bar to make sure it is installed correctly.

Possible Causes

Low resistance across pins 10 and 11 can be caused by:

A poorly mated air bag clock-spring connector may not push the shorting bars back into their fully retracted positions.
A faulty shorting bar may short Circuits 614 and 615 together.
A short in the clock-spring winding's between Circuits 614 and 615.
A short across the air bag terminals within the air bag. DO NOT attempt a direct resistance measurement of the air bag. Follow the diagnostic procedures to determine if the air bag resistance is lower than normal.
