B1455

General Description

Rear Side Impact Sensor(RSIS) is located in both side of rear seat back panel detects rear side collision. When RSIS delivers collision signal to SRSCM, SRSCM checks whether safing sensor located in SRSCM detects collusion. And if both RSIS and safing sensor detects collision simultaneously, SRSCM operates rear side air bag.

DTC Description

The SRSCM sets DTC B1452/B1455 if there is short to power harness in RDSIS/RPSIS harness.

SCHEMATIC DIAGRAM





Monitor Scantool Data

1. Ignition "OFF", connect scantool.
2. Ignition "ON"& Engine "OFF", select "Diagnostic Trouble Codes(DTC)" mode.
3. Monitor diagnostic trouble code and present of trouble code.
4. Using a scantool, clear the DTC.




5. Is DTC present problem ?
YES
> Go to "W/Harness Inspection" procedure.
NO
> Displaying nothing(no DTC) or DTC with label "H"(historical) shows that Fault is intermittent caused by poor contact in the part's and/or SRSCM connector or was repaired and SRSCM memory was not cleared.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
> Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
YES
> Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
> Go to "Main harness circuit inspection" procedure.

Main harness Circuit Inspection

1. Ignition "OFF".
2. Disconnect the battery (-) terminal cable from the battery, and wait at least one minutes.
3. Disconnect RSIS connector and SRSCM main harness connector.
4. Ignition "ON" & Engine "OFF".
5. Measure voltage between terminal "1" or "2" of the RSIS harness connector and chassis ground.

Specification : 0V





6. Is the measured voltage within specifications?
YES
> Go to "Component Inspection" procedure.
NO
> Substitute the SRS main harness and check for proper operation.
If the problem is corrected, replace SRS main harness and then go to "Verification of Vehicle Repair" procedure.

Component Inspection

1. Ignition "ON" & Engine "OFF" and Using a scantool, clear the DTC.
2. Ignition "OFF".
3. Disconnect the battery (-) terminal cable from the battery, and wait at least one minutes.
4. Disconnect RSIS connector.
5. Substitute the RSIS and check for proper operation.
6. Is DTC present problem ?
YES
> Substitute a known-good SRSCM, and check for proper operation.
If the problem is corrected, replace SRSCM and then go to "Verification of Vehicle Repair" procedure.
NO
> Substitute a known-good RSIS, and check for proper operation.
If the problem is corrected, replace RSIS and then go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.
1. Connect scan tool and select "Diagnostic Trouble Codes(DTC)" mode.
2. Using a scan tool, clear the DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are any DTC present ?
YES
> Go to the applicable troubleshooting procedure.
NO
> System is performing to specification at this time.
