DESCRIPTION
The front airbag sensor LH circuit consists of the center airbag sensor assembly and front airbag sensor LH.
The front airbag sensor LH 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 LH 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 LH. 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 LH. Also disconnect the connectors that link the engine room main wire and instrument panel wire.
(e) Check that the terminals of connectors are not damaged.
OK:
The terminals are not deformed or damaged.
