### DTC B1610/13 Front Airbag Sensor RH Circuit Malfunction

## for Preparation Click here

## SYSTEM DESCRIPTION

The front airbag sensor RH consists of the diagnostic circuit and front deceleration sensor. The center airbag sensor receives signals from the front deceleration sensor and determines whether or not the SRS should be activated.
DTC B1610/13 is recorded when a malfunction is detected in the front airbag sensor RH circuit.

DTC No. | DTC Detection Condition | Trouble Area

1. Turn the ignition switch OFF.

1. Turn the ignition switch ON, and wait for at least 60 seconds.

1. Check for DTCs (Click here).

   OK:
     DTC B1610/13 is not output.

   HINT:
     DTCs other than DTC B1610/13 may be output at this time, but they are not related to this check.

| NG |

Go to step 2

OK |

USE SIMULATION METHOD TO CHECK

2.CHECK CONNECTION OF CONNECTORS

1. Turn the ignition switch OFF.

1. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.

1. Check that the connectors are properly connected to the center airbag sensor and front airbag sensor RH.

   OK:
     Connectors are connected.

| NG |

CONNECT CONNECTORS, THEN GO TO STEP 1

OK |

3.CHECK FRONT AIRBAG SENSOR RH CIRCUIT (OPEN)

1. Disconnect the connectors from the center airbag sensor and front airbag sensor RH.

1. Using a service wire, connect terminals A14-27 (-SR) and A14-29 (+SR) of connector B.

   NOTICE:
     Do not forcibly insert a service wire into the terminals of the connector.

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     Tester Connection | Specified Condition
     A6-2 (+SR) - A6-1 (-SR) | Below 1 Ω

| NG |

Go to step 8

OK |

4.CHECK FRONT AIRBAG SENSOR RH CIRCUIT (SHORT)

1. Disconnect the service wire from connector B.

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     Tester Connection | Specified Condition
     A6-2 (+SR) - A6-1 (-SR) | 1 MΩ or higher

| NG |

Go to step 9

OK |

5.CHECK FRONT AIRBAG SENSOR RH CIRCUIT (TO B+)

1. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.

1. Turn the ignition switch ON.

1. Measure the voltage of the wire harness side connector.

   Standard voltage:

     Tester Connection | Specified Condition
     A6-2 (+SR) - Body ground | Below 1 V
     A6-1 (-SR) - Body ground | Below 1 V

| NG |

Go to step 10

OK |

6.CHECK FRONT AIRBAG SENSOR RH CIRCUIT (TO GROUND)

1. Turn the ignition switch OFF.

1. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     Tester Connection | Specified Condition
     A6-2 (+SR) - Body ground | 1 MΩ or higher
     A6-1 (-SR) - Body ground | 1 MΩ or higher

| NG |

Go to step 11

OK |

7.CHECK FRONT AIRBAG SENSOR RH

1. Connect the connectors to the center airbag sensor.

1. Interchange the front airbag sensor RH with the front airbag sensor LH and connect the connectors to them.

1. Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.

1. Turn the ignition switch ON, and wait for at least 60 seconds.

1. Clear the DTCs (Click here).

1. Turn the ignition switch OFF.

1. Turn the ignition switch ON, and wait for at least 60 seconds.

1. Check for DTCs (Click here).

   Result:

     Result | Proceed to
     DTC B1610/13 is output | A
     DTC B1615/14 is output | B
     DTC B1610/13 and B1615/14 are not output | C

| A |

REPLACE CENTER AIRBAG SENSOR ASSEMBLY

| B |

REPLACE FRONT AIRBAG SENSOR RH

C |

USE SIMULATION METHOD TO CHECK

8.CHECK ENGINE ROOM MAIN WIRE (OPEN)

1. Disconnect the engine room main wire connector from the instrument panel wire.

1. Using a service wire, connect terminals A6-1 (-SR) and A6-2 (+SR) of connector E.

   NOTICE:
     Do not forcibly insert a service wire into the terminals of the connector when connecting.

1. Measure the resistance of the wire harness side connector.

   Standard resistance:

     Tester Connection | Specified Condition
     IF1-1 (+SR) - IF1-2 (-SR) | Below 1 Ω

| NG |

REPAIR OR REPLACE ENGINE ROOM MAIN WIRE

OK |
