12. Measure the resistance between each terminal of
the SRS simulator lead and body ground. There
should be an open circuit or at least 1 M .
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

3. Turn the ignition switch to LOCK (0). Disconnect the negative cable from the battery, then wait at least 3
minutes.
4. Remove the B-pillar lower trim (see page 20-72), then disconnect the floor wire harness 4P
connector (A) from the driver’s seat belt tensioner.
5. Connect the SRS inflator simulator (2 connectors) and simulator lead K to the floor wire
harness.
