B1395

DTC B1395
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
1. Visually inspect all connectors related to the affected circuit for damage and secure connection.
2. Inspect terminals for damage and corrosion.

CAUTION: Avoid damaging connectors during the inspection process.

3. Are any problems found?

NO - Go to next step (INSPECTION PROCEDURE).

YES - After repairing the trouble part, check whether DTC occurs or not.

INSPECTION PROCEDURE
1. PREPARATION
1. Turn the ignition switch to LOCK.
2. Disconnect the battery negative cable from the battery and wait for at least 3 minutes.
3. Remove the DAB module and disconnect the DAB connector.
4. Disconnect the connectors of the PAB, SAB, CAB, BPT, FIS and SIS.
5. Disconnect the SRSCM connector.

2. CHECK SHORT CIRCUIT
A. 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

B. Is the measured resistance within specification?

YES - Go to nest step.

NO - Repair or replace the wiring harness between two squibs.

3. CLEAR THE DTC AND CHECK THE VEHICLE AGAIN
1. Install the DAB module and connect the DAB connector.
2. Connect the connector of the PAB, SAB, CAB, BPT, FIS and SIS.
3. Connect the SRSCM connector.
4. Connect the battery negative cable to the battery.
5. Connect a Hi-Scan (Pro) to the data link connector.
6. Turn the ignition switch to ON.
7. Clear the DTC stored in the SRSCM memory with the Hi-Scan (Pro)
8. Turn the ignition switch to LOCK and wait for at least 30 seconds.
9. Turn the ignition switch to ON and wait for at least 30 seconds.
10. Check the vehicle again with the Hi-Scan(Pro).
Does the above DTC(s) go off?

YES - Problem is intermittent or was repaired and SRSCM memory was not cleared.

NO - Replace the SRSCM with a new one and then check the vehicle again. At this time, if the vehicle normally operates with a new one, the fault may be the SRSCM. Replace the SRSCM.
