DESCRIPTION
The front airbag sensor RH consists of parts such as the diagnostic circuit and the frontal detection sensor.
When the airbag sensor assembly receives signals from the frontal deceleration sensor, it determines whether or not the SRS should be activated.
DTC B1610/13 is set when a malfunction is detected in the front airbag sensor RH circuit.

CAUTION / NOTICE / HINT
NOTICE:
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work (See page ).
PROCEDURE
1. |
CHECK CONNECTION OF CONNECTORS |
(a) Turn the ignition switch off.
(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
(c) Check that the connectors are properly connected to the airbag sensor assembly and the front airbag sensor RH.
OK:
The connectors are properly connected.
