Clock spring question

Replaced clock spring cable with $210 genuine Toyota part from a Toyota dealer.
While it fixed steering wheel buttons and horn, the driver side airbag still is on. Resetting airbag by unplugging yellow cable under the seats didn't do anything
The dtc code I had received was b1801/51

What should I do next ? Thanks

 

See this post.

 

Saw the manual in SFO's posting.

Do you have part# for
REPLACE HORN BUTTON ASSY
REPLACE AIRBAG ASSY

If it's not expensive I'll replace HORN button assy and if that does not work airbag assy

 

In the procedure SFO posted, if you were looking for other things to speculatively replace, all I see are "HORN BUTTON ASSY" (that's the actual air bag), the "AIR BAG ECU ASSY" (that's the central air bag computer down on the front floor), the "INSTRUMENT PANEL WIRE" (harness), and the "SPIRAL CABLE SUB-ASSY" (that you already replaced).

None of those will be inexpensive.
