Ground

Is the resistance as specified?

YES -Go to step 15.

NO -Short to ground in dashboard wire harness B, floor wire harness or ODS unit harness; replace the
faulty harness.

15. Measure the resistance between the No. 14 terminal of SRS unit connector A (28P) and the No. 7 terminal

of the ODS unit harness 18P connector. There should be 0-1.0 ohms.
