Fit Verification Mechanism

The mechanism is used to electrically check the engagement of the connector between the SRS diagnosis unit and body wiring harness. The operating principle is described below.

1. Securely connect the SRS diagnosis unit and harness side connectors and press the secondary lock lever down to lock the connectors.

2. At this time, the short bar provided on the rear surface of the secondary lock lever produces a short circuit across terminals No. 7 and 8 of the SRS diagnosis unit. The SRS diagnosis unit supplies monitoring current to the circuit to electrically verify that the connectors have been locked.
