B1115 SATELLITE SENS RH
Description
INFOID:0000000000959690
DTC B1115 [COMM FAIL] SATELLITE SENS RH
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.

CAUTION:
• Before servicing, turn ignition switch OFF, disconnect both battery terminals and wait at least 3 min-
utes. (To discharge backup capacitor.)
• Do not use unspecified tester or other measuring device.
DIAGNOSTIC PROCEDURE
1.
CHECK HARNESS CONNECTOR
Check the harness connector.
Are connections of harness connectors and terminals correct?
YES
>> GO TO 2.
NO
>> Repair or replace harness connectors.
2.
CHECK WIRING HARNESS
Check the wiring harness.
Is the outside of wiring harness normal, without any damage?
YES
>> GO TO 3.
NO
>> Replace wiring harness.
3.
CHECK SATELLITE SENSOR
Check the displayed on CONSULT-lll.
Is “SATELLITE SENSOR” displayed on CONSULT-lll?
YES
>> Replace satellite sensor.
NO
>> Replace diagnosis sensor unit (ACU).
