3. Disconnect the following connector.

SRS unit connector B (39P)

4. Connect the SRS short canceller to SRS unit connector B (39P) terminals No. 20 and No. 21.
5. Measure the resistance between test points 1 and 2.

Is there an open circuit, or at least 1 MΩ?

YES

The READ+ and READ- wires are OK. Faulty SRS unit or poor connection at SRS unit connector B (39P) and the SRS unit. Check the connection; if the connection is OK, replace the SRS unit. If the DTC does not clear, replace the floor wire harness.
