Volvo: check engine light on & ABS light on,srs light, volvo 850 t5, srs system

Question
MY 1996 VOLVO 850 T5 HAS A SMELL COMING THROUGH THE VENTS INTO THE CABIN.OUTSIDE THE CAR WHEN IDLING IT GIVES OFF THESE SMELLY FUMES,I WAS TOLD MY CATALYTIC CONVERTER IS BLOWN IS THAT POSSIBLE OR CAN IT BE SOMETHING ELSE. MY CHECK ENGINE LIGHT IS ON AND ABS LIGHT GOES ON AND OFF WHEN DRIVING BUT WHEN I HAD AN ELECTRONIC SCAN DONE EVERYTHING CHECKED OUT OKAY BUT I CANNOT CLEAR THE LIGHTS, WHAT CAN THE PROBLEM BE… A COUPLE OF MONTHS AGO I HAD MY HEAD DONE OVER CAN THIS BE A CONTRIBUTING FACTOR. THE CAR I BOUGHT WAS IN AN ACCIDENT AND I HAD IT FIXED.I REPLACED THE POPPED AIRBAG BUT THE TENSIONER MUST ALSO BE REPLACE IN ORDER TO CANCEL THE SRS LIGHT,CAN I BYPASS THE TENSIONER WITH A RESISTOR TO CANCEL THE SRS LIGHT BECAUSE I WAS TOLD THIS WILL.

Answer
Hello! I would suggest you have the car checked by A VOLVO technician with the proper diagnostic tools. If all of those light are on, a scan should show a fault. The ABS problem is most likely an ABS module. It is very common. The check engine light can be caused by a number of things. Only a proper scan tool from Volvo will diagnose it right. I would not suggest by-passing anything in the SRS system. That could be dangerous!
