Measure the resistance between the No. 1 terminal of SRS unit connector B (39P) and the No. 7 terminal of the OPDS unit harness 18P connector. There should be 0−1.0 Ω.
Open between the No. 1 terminal of the SRS unit connector B (39P) and the No. 7 terminal of the OPDS unit harness 18P connector (dashboard wire harness, right side wire harness, SRS floor wire harness, or OPDS unit harness); replace the faulty harness.■
