Hello?
Expert:  Richard replied 1 year ago.

That is a network communication fault with the ABS module. This will not normally just turn the engine light in as you would also see a DSC, gearbox and park brake fault warnings also on.

Expert:  Richard replied 1 year ago.

I recommend we try using a different scan tool as I suspect there are other codes logged.

Expert:  Richard replied 1 year ago.

I would see if the warning goes out if you clear the code with your tool but I do not want to do that until we can confirm the codes with another tool.

Customer: replied 1 year ago.
I scanned it twice with the generic obd 2 scanner as well as the snap on verdict 7
Expert:  Richard replied 1 year ago.

No other warning lights or messages on? Did you try clearing the code?

Customer: replied 1 year ago.
With the same results
Customer: replied 1 year ago.
Haven't cleared it yet as I'm awaiting for your direction
Expert:  Richard replied 1 year ago.

Does the code return right away? Aby other warning lights or messages on?

Expert:  Richard replied 1 year ago.

Ok I really think there is another code that the tool is not reading.

Customer: replied 1 year ago.
No other codes at the moment. Shold I clear the code?
Expert:  Richard replied 1 year ago.

I would try and clear it to see if the tool will clear the code and/or the code comes right back.on and the engine light comes right back.

Customer: replied 1 year ago.
Code cleared and there were no reoccurrences of any other code for the time being
Expert:  Richard replied 1 year ago.

Ok good. Let me know if anything changes.
