from the left side impact sensor (first) (see page
24-14).

6. Disconnect SRS unit connector C (28P) from the

SRS unit (see step 7 on page 24-26).

7. Measure the resistance between the No. 11 and

No. 12 terminals of SRS unit connector C (28P).
There should be an open circuit or at least 1 M

Go to step 8.

Short in the floor wire harness; replace the
