retrieved, replace clockspring. Go to step 8 .
6. Disconnect SRS ECU connector C-26 and clockspring connector C-307. Insert
a cable tie or similar insulator between terminals No. 11 (Yellow/Black wire)
and No. 12 (Yellow wire) of SRS ECU connector to release shorting bar. See
Fig. 21
. Check for continuity between terminals No. 11 and 12. If continuity
exists, go to next step. If continuity does not exist, erase, then retrieve DTCs
using scan tool. If DTC 21 is retrieved, replace SRS ECU. Go to step 8 .
7. Check wire harness between SRS ECU connector C-26 and lower clockspring
connector C-307 for a short circuit. If wire harness is okay, go to next step. If
wire harness has a short circuit, replace wire harness. Go to next step
