Disconnect the TL1o and TR1o connectors (A) from the TL1i and TR1i connectors (B). Disconnect the U1o connector (A) from the SRS unit (B).

Check resistance between the No. 7 and the No. 16 terminals of the U1o connector. There should be 2.0 - 3.0 ohm. U1o CONNECTOR Wire side of female terminals Is the resistance as specified? YES - Faulty SRS unit or poor contact at the U1o connector and the SRS unit, check the connection between the U1o connector and the SRS unit. If the connection is OK, replace the SRS unit (see page 23-176). NO - Go to step 14. Disconnect the cable reel from dashboard wire harness B.
