B1026, B1027, B1028, B1029, B1030, B1031 DIAGNOSIS SENSOR UNIT
DescriptionINFOID:0000000003813945
Check the whole SRS and displays the malfunction either by illuminating or blinking the air bag warning lamp
in the combination meter. Malfunctioning part can be detected by on board self-diagnosis system and CON-
SULT-III.
OPERATION
It detects a shock that exceeds a specified level and monitors whether the driver and passenger air bags, front
side air bag, side curtain air bag and pre-tensioner seat belts operate normally.
STRUCTURE
It contains the “G” sensors for both frontal and side collisions and spare battery function in case of main bat-
tery damage in collision.
INSTALLATION
Air bag diagnosis sensor unit is installed under the center console with fixed bolts.
DTC LogicINFOID:0000000003813946
DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAG RESULT
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “AIR BAG” Self Diagnostic Result.
Without CONSULT-III
1. Turn ignition switch ON.
2. Check the air bag warning lamp status. Refer to SRC-10, "
Air Bag Warning Lamp Diagnosis".
NOTE:
SRS does not enter Diagnosis mode if no malfunction is detected in User mode.
Is malfunctioning part detected?
YES >> Refer to SRC-22, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003813947
WARNING:
 Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes. (To discharge backup capacitor.)
 Never use unspecified tester or other measuring device.
1.CHECK HARNESS CONNECTOR
Check the harness connector.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace harness connectors.
2.CHECK WIRING HARNESS
Check the wiring harness externals.

B1033, B1034 CRASH ZONE SEN
DescriptionINFOID:0000000003813948
Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level caused by
vehicle frontal collision.
OPERATION
When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor and the safing algorithm to
be that of collision which exceeds specified level, the driving circuit switches on and feeds the electric ignitor of
both driver and passenger air bags and pre-tensioner seat belts.
STRUCTURE
Integrated type of the “G” sensor element for frontal collision with output terminals for signal voltage.
INSTALLATION
Crash zone sensor is installed on the radiator core support assembly with fixed nuts.
