B1120 SATELLITE SENS LH
Description
INFOID:0000000001069852
DTC B1120 [COMM FAIL] SATELLITE SENS LH
Main “G” sensor generates signal voltage when it detects deceleration beyond the specified level by vehicle
side collision.
OPERATION
When ACU defines both signal voltage of the “G” sensor and the Safing sensor to be that of collision which
exceeds specified level, the driving circuit switches on and feed the electric ignitor of both the side air bag and
curtain air bag.
STRUCTURE
Integrated type of the “G” sensor element for side collision with output terminals for signal voltage.
INSTALLATION
Satellite sensor is installed at the underside of center pillar with fixed nuts.

YES
>> GO TO 2.
NO
>> Repair or replace harness connectors.
2.
CHECK WIRING HARNESS
Is the outside of wiring harness normal, without any damage?
YES
>> GO TO 3.
NO
>> Replace wiring harness.
3.
CHECK SATELLITE SENSOR
Is “SATELLITE SENSOR” displayed on CONSULT-III?
YES
>> Replace satellite sensor.
NO
