Disconnect the U2o connector (A) from the SRS unit (B). Check resistance between the No. 3 terminal of the U2o connector and body ground. There should be 1 M ohm or more. U2o CONNECTOR Wire side of female terminals Is the resistance as specified? YES - Go to step 22. NO - Short to ground in the floor wire harness or in the OPDS unit harness; replace the faulty harness.

Check resistance between the No. 3 terminal of the U2o connector and the No. 7 terminal of the O1i connector. There should be 0 - 1.0 ohm. U2o CONNECTOR Wire side of female terminals Is the resistance as specified? YES - Go to step 23. NO - Open in the floor wire harness or in the OPDS unit harness; replace the faulty harness.
