the SRS simulator lead and body ground. There
should be an open circuit or at least 1 M .

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.
