Toyota Sienna Service Manual: Half Connection in Center Airbag Sensor Assembly Connectors
DTC B1135/24 Half Connection in Center Airbag Sensor Assembly Connectors
DESCRIPTION
The center airbag sensor assembly connector has a mechanism that electrically detects half connection.
The center airbag sensor assembly monitors the voltage applied to the disconnection detection pins and detects half connection.
DTC B1135/24 is recorded when the center airbag sensor assembly detects an open circuit in the electrical connection check mechanism of the airbag sensor connector or in the airbag sensor circuit.
INSPECTION PROCEDURE
1 CHECK CENTER AIRBAG SENSOR ASSEMBLY CONNECTOR
- Turn the ignition switch to the LOCK position.
- Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
- Check the connection of the center airbag sensor assembly connectors.
OK: The connectors are connected.
HINT: When the connectors are not firmly connected, disconnect them once and reconnect them securely
2 CHECK CENTER AIRBAG SENSOR ASSEMBLY
- Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
