Using a scantool, clear the DTC.
Every air bag module has its firing circuit to deploy air bag according to signal of SRSCM.SRSCM checks every air bag module when ignition "ON". Once any fault is detected, it is erased only by scantool.
The SRSCM sets DTC B1395 if there's any short circuit in harness of every firing circuit to one another.
Item | Detecting Condition | Possible cause | |
DTC Strategy | ● Check current(PWM type) | ● Short circuit among squib harnesses. ● SRSCM. | |
Enable Conditions | ● Ignition "ON" | ||
Threshold Value | ● Only check during start-up phase | ||
Diagnostic Time | Qualification | ● More than 1sec | |
De-Qualification | ● N/A | ||
Ignition "OFF", connect scantool.
Ignition "ON"＆ Engine "OFF", select "Diagnostic Trouble Codes(DTC)" mode.
Monitor diagnostic trouble code and present of trouble code.
Using a scantool, clear the DTC.
Is DTC present problem ?
▶ Check for short between ignition circuits of DAB,PAB,BPT,CAB,SAB. If the condition of harness and component is OK, this fault is caused by SRSCM internal error so replace a known-good SRSCM and then go to "Verification of vehicle Repair" procedure.
▶ 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.
