5. Disconnect the rear harness 3P connector from the passenger's seat belt buckle switch 3P connector (A).
6. Buckle the passenger's seat belt.
Measure the resistance between the No. 1 and No. 3 terminals of the passenger's seat belt buckle switch 3P connector. There should be 0 - 1.0 ohms.
Measure the resistance between the No. 1 and No. 2 terminals of the same connector. There should be an open circuit or at least 1 Mohms.
Are the resistances as specified?
YES - Go to step 7.
NO - Replace the passenger's seat belt buckle assembly, then clear the DTC.
7. Unbuckle the passenger's seat belt.
Measure the resistance between the No. 1 and No. 2 terminals of the passenger's seat belt buckle switch 3P connector. There should be 0 - 1.0 ohms.
Measure the resistance between the No. 1 and No. 3 terminals of the same connector. There should be an open circuit or at least 1 Mohms.
Are the resistances as specified?
YES - Go to step 8.
NO - Replace the passenger's seat belt buckle assembly, then clear the DTC.
8. Measure the resistance between the No. 2 terminal of the passenger's seat belt buckle switch 3P connector and body ground, and between the No. 3 terminal and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Go to step 9.
NO - Replace the passenger's seat belt buckle assembly.
9. Disconnect the negative cable from the battery, then wait for 3 minutes.
10. Disconnect both seat belt tensioner 2P connectors from the SRS main harness.
11. Disconnect SRS unit connector B (28P) from the SRS unit.
12. Measure the resistance between the No. 2 terminal of the rear harness 3P connector and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Go to step 13.
NO - Short to ground in the rear harness or SRS main harness; replace the faulty harness.
13. Measure the resistance between the No. 3 terminal of the rear harness 3P connector and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Faulty SRS unit; replace the SRS unit.
NO - Short to ground in the rear harness or SRS main harness; replace the faulty harness.
