DESCRIPTION
The front airbag sensor RH circuit consists of the center airbag sensor assembly and front airbag sensor RH.
The front airbag sensor RH detects impacts to the vehicle and sends signals to the center airbag sensor assembly to determine if the airbag should be deployed.
These DTCs are stored when a malfunction is detected in the front airbag sensor RH circuit.

WIRING DIAGRAM
PROCEDURE
1. |
CHECK CONNECTORS |
(a) Turn the ignition switch off.
(b) Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
(c) Check that the connectors are properly connected to the center airbag sensor assembly and front airbag sensor RH. Also check that the connectors that link the engine room main wire and instrument panel wire are properly connected.
OK:
The connectors are properly connected.
HINT:
If the connectors are not connected securely, reconnect the connectors and proceed to the next inspection.
(d) Disconnect the connectors from the center airbag sensor assembly and front airbag sensor RH. Also disconnect the connectors that link the engine room main wire and instrument panel wire.
(e) Check that the connector terminals are not damaged.
OK:
The terminals are not deformed or damaged.
