16. Disconnect SRS unit connector A (28P) from the SRS unit. Technician Safety Information

17. Disconnect the SRS inflator simulator from the SRS simulator lead. Do not disconnect the simulator lead from the SRS main harness 4P connector.

18. Measure the resistance between the terminals of the SRS simulator leads. There should be less than 1.0 Ohms.

Is the resistance as specified?
YES - Faulty SRS unit or poor connection at SRS unit connector A (28P) and the SRS unit. Check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit. Service and Repair
