General Description

BCM (PAS) is a parking assistant system. It has a supersonic sensor which radiates supersonic to front and rear side of the vehicle to detect supersonic reflected from an obstacle. It calculates distances between vehicle and obstacle if it detects reflected supersonic. It warns being obstacle to drivers through buzzer or displaying on cluster according to distance from obstacle. Warning level is divided into 3 step (warning level rises progressively according to distance from obstacle)

DTC Description

This code reports an error in LIN line. The purpose is to verify the status of BCM (PAS), Sensor and Wire when error is detected at PAS of Front Left Side Sensor.

BCM (PAS) is a parking assistant system. It has a supersonic sensor which radiates supersonic to front and rear side of the vehicle to detect supersonic reflected from an obstacle. It calculates distances between vehicle and obstacle if it detects reflected supersonic. It warns being obstacle to drivers through buzzer or displaying on cluster according to distance from obstacle. Warning level is divided into 3 step (warning level rises progressively according to distance from obstacle)

This code reports an error in LIN line. The purpose is to verify the status of BCM (PAS), Sensor and Wire when error is detected at PAS of Rear Right Side Sensor.

Repair or replace as necessary and then go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure.

1. Many malfunctions in the electrical system are caused by poor harness (es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found? YES Repair as necessary and go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure. NO Go to " «SMK SIGNAL CIRCUIT INSPECTION»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis__smk-signal-circuit-inspection) " procedure.

SMK Signal Circuit Inspection

1. Check CAN High Line IG "ON" & ENG "OFF". After connect GDS, select "Oscilloscope" mode. Measure the signal waveform on SMK CAN High line. Specification : Refer to " «SIGNAL WAVEFORM»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " Does the measured signal waveform follow the specification? YES Go to " 2 CAN Low Line Inspection" procedure. NO Check short to battery or ground. Repair as necessary and go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure.
2. Check CAN Low Line IG "ON" & ENG "OFF". After connect GDS, select "Oscilloscope" mode. Measure the signal waveform on SMK CAN Low line. Specification : Refer to " «SIGNAL WAVEFORM»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " Does the measured signal waveform follow the specification? YES Go to " «COMPONENT INSPECTION»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure. NO Check short to battery or ground. Repair as necessary and go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure.

1. Check internal errors of CAN communication units. Connect GDS. IG "ON" and engine "OFF". Select "DTC Analysis" mode. Replace SMK with the new one and check DTC again. Is the code erased? YES Substitute with a known - good unit and check for proper operation. If the problem is corrected, replace the unit and go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure. NO Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to " «VERIFICATION OF VEHICLE REPAIR»(/hyundai/santa-fe/iii-2012-2016/remont/communication-devices/#body-control-module-bcm-diagnosis) " procedure.

After a repair, it is essential to verify that the fault has been corrected.

1. Connect scantool and select "DTC Analysis" mode.
2. Clear the DTCs and Operate the vehicle within DTC Enable conditions in General information.
3. Is any DTC outputted again? YES Go to the applicable troubleshooting procedure. NO System performing to specification at this time.
