B1395 means the SRSCM found two firing circuits shorted to each other. Every airbag and pretensioner has its own pair of wires back to the module, and those pairs are supposed to stay electrically separate. When the module pulls one line down and sees another follow it, it stores B1395 and stops trusting the circuits it just tested.
Each airbag module and each belt pretensioner has a firing circuit with an initiator in it, and the SRSCM checks every one of them when the ignition goes to on. Hyundai describes the test as a current check on a pulse width modulated line: the module sinks the other lines, looks at one line at a time, and if that line reads below 0.6 volts while the rest are pulled down, it has found two loops cross coupled. The condition has to hold for more than 2 milliseconds three times over before the code qualifies.
Hyundai lists two possible causes. The first is a short circuit in the squib harness, meaning two firing loops touching somewhere in the wiring. The second is the SRSCM itself. The order matters, because the wiring is cheap to inspect and the module is not.
One detail changes how the repair goes. Hyundai's description states that once this test detects a fault, it is erased only by a scan tool. The code will not fall out of memory on its own after the wiring is fixed, so the light stays on until someone clears it and lets the module retest.
Circuit, with a real chance of ending at the module. B1395 is not a deployment record and it does not mean any airbag has fired. It is a live electrical test result. Hyundai's diagnostic path says to check for a short between the ignition circuits of the driver airbag, passenger airbag, belt pretensioners, curtain airbags, and side airbags first. If the harness and every one of those components is sound, the chart calls the fault an SRSCM internal error and moves to substituting a known good module.
Only after the circuit is right. Clearing memory while two loops are still shorted together lets the module find the same fault at the next key on. Repair the wiring, clear the code, and confirm it stays gone. If every airbag, pretensioner, and connector checks out and the code still returns, the module is the suspect, and that is our work. Send it in and we test it before anything gets spent, and a stored crash record from a collision on the same vehicle is handled by an airbag module reset.
B1395 comes from the SRSCM code map Hyundai and Kia share across most of their model lines, and Genesis vehicles on the same restraint architecture read it the same way. A useful scan tool check on these cars is the all airbag resistance parameter in current data, specified between 0.9 and 6.6 ohms on the vehicle these figures come from. An open, a short to battery, or a short to ground in any firing circuit fails that reading.
Work the harness before the parts. Start wherever the interior has been apart most recently, because cross coupled firing loops almost always follow someone routing, pinching, or re-pinning a connector. Look under both front seats, behind the instrument panel at the passenger airbag, and along the sills where curtain and side airbag wiring runs. A connector forced together at an angle can bridge two circuits with no visible damage to the wire.
Watch whether the code reads as current or historical. A historical label on these modules points at an intermittent connection rather than a hard short, and the fix is a careful connector inspection instead of a parts swap. Related codes include B1341 for cross coupled crash sensor circuits, along with B1346 and B1352 when a single loop reads out of range on its own.
