DTC B1395 SQUIB INTERCONNECTION FAULT 

DTC DESCRIPTION 

While start up phase, SRSCM will measure cross link of squibs. If one of them is failed during interconnection 
test, then SRSCM will store interconnection fault. Once the interconnection fault is detected, it remains active 
continuously till the fault is erased. Only one fault code is assigned for all interconnection fault. 

TERMINAL & CONNECTOR INSPECTION 

Refer to TERMINAL & CONNECTOR INSPECTION. 

INSPECTION PROCEDURE 

1. PREPARATION 

Refer to PREPARATION OF INSPECTION. 

2. CHECK SHORT CIRCUIT 

1. Measure resistance between following squibs. (DAB - PAB, DAB - SAB, DAB - CAB, DAB - 

BPT, PAB - SAB, PAB - CAB, PAB - BPT, SAB - PAB, SAB - CAB, SAB - BPT, CAB - BPT) 

Specification (resistance): infinite 

2. Is the measured resistance within specification? 

YES  



Go to next step.  

NO  



Repair or replace the wiring harness between two squibs.  

3. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN 

Refer to CLEAR THE DTC AND CHECK THE VEHICLE AGAIN.

DTC B1400 SIDE IMPACT SENSOR [FRONT-DRIVER] DEFECT; DTC B1403 SIDE IMPACT 
SENSOR [FRONT-PASSENGER] DEFECT; DTC B1409 SIDE IMPACT SENSOR [FRONT-DRIVER] 
COMMUNICATION ERROR; DTC B1410 SIDE IMPACT SENSOR [FRONT-PASSENGER] 
COMMUNICATION ERROR 

DTC DESCRIPTION 

The detecting system for side crash consists of the SRSCM and four Side Impact Sensors (SIS). The SRSCM 
sets above DTC (s) if it detects that any SIS is defective or there is communication error between any SIS and 
the SRSCM.

3. Is the measured resistance within specification? 

YES  



Check Side Impact Sensor.  

NO  



Repair or replace the wiring harness between the SIS and the SRSCM.  

4. CHECK THE SIDE IMPACT SENSOR  

1. Replace the Side Impact Sensor (SIS) with a new one. 



Refer to "SIDE IMPACT SENSOR (SIS) ".  

2. Install the DAB module and connect the DAB connector.  

3. Connect the connectors of the PAB, SAB, CAB, BPT, FIS and SIS.  

4. Connect the SRSCM connector.  

5. Connect the battery negative cable to the battery.  

6. Connect a Hi-Scan (Pro) to the data link connector.  

7. Turn the ignition switch to ON and check the vehicle again.
