Opening the SRS Unit Shorting Connectors for Diagnosis

Special Tools Required 

SRS Short Canceller 070AZ-SAA0100 

NOTE:
  • To prevent damage to the connector cavity, insert an SRS short canceller straight into the cavity from the terminal side.
  • Before installing an SRS short canceller, wash it with electrical contact cleaner, then dry it with compressed air.
  • Do not use an SRS short canceller if it is damaged.
  • Make sure to remove an SRS short canceller before reconnecting the SRS unit connector.
  • Some systems store data in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection .

When SRS unit connectors A (39P) and B (39P) are disconnected, short circuits are automatically created in the connector to prevent accidental deployment of an airbag or tensioner. The circuit may need to be opened sometimes when diagnosing the system. Insert an SRS short canceller in the specified cavities when necessary to keep the circuit open for diagnosis.
