B1352 HYUNDAI, KIA: PASSENGER SIDE AIR BAG MODULE LOW FIRST STAGE RESISTANCE
When the ignition switch is turned on, the SDM (Sensing and Diagnostic Module) checks for faults within the module itself by means of ignition tests. If no problems are found in the results of these tests, the ignition and deployment loop voltages are measured to ensure that they are within the proper voltage ranges.
The deployment loop voltages are also monitored by the SDM to check the driver and passenger side for a short-to-ground or open circuit. The electrical connections to the Passenger Airbag Module are checked by allowing infinitesimal current to pass through the internal circuit and checking the resistance.
When the B1352 OBDII diagnostic code is set, it is because the passenger front deployment loop has exhibited a low resistance condition, being below 1.77 ohms.
The reasons for setting the B1352 OBD2 fault code are as follows:
The steps to troubleshoot DTC B1352 OBDII code are:
