Hi Desmond .

What code reader are you using.

Customer: replied 4 years ago.

snapon Modis global obd11

Hi Desmond .

Just reading up on this issue and the codes you have is a common issue due to hairline cracks in the catalytic converter ,hard to see and detect but check carefully if you see a crack then replace .

Get back to me with what you find .

cat s are brand new read original question.i was hoping for other suggestions.have you ever seen the need for ecm software corrections

Expert:  Greg replied 4 years ago.
Hi Desmond .

Sorry cats new ,sensors new .this leaves me to say you have to get hooked up to a dealer level scan tool to check for codes as the codes you have are global codes and not
manufactured codes as with the RR code list these codes are not listed .
Do you not have the RR software on your Snappy .or do you have the chance to use a MaxiDas 780 or a launch , these will get you the manufactured codes .

RR codes start with P1171 -72 -74 and 75.

Hi .

Yes there is a software correction for the P1171 and 72 TSB ref number LM303-11.

This is why might be a good idea to try another scan tool .
