Icarsoft i980
Expert:  Kevin replied 8 months ago.

Ok these codes dont exsist on my system il opt out see if another tech can help

Expert:  sprinkles08 replied 8 months ago.

Hello and welcome to JustAnswer!

Depending on the actual code setting there could be a sensor, wiring, ABS module, tone wheel or tire circumference issue, but if the sensor signal is now present and seems to match the rest then I'm not sure that a code for the right front is still setting.

Do you have the actual C code numbers that are setting? They will start with a C and have at least four digits.

Customer: replied 8 months ago.
No I do not have a C code. The previous codes from the icarsoft i980 is all I have.
Expert:  sprinkles08 replied 8 months ago.

Can you double check to see what is actually setting? It may show proprietary codes but the standardized C codes should be there. It's required to report in that form.

Customer: replied 8 months ago.
Does the code p2004 or u140a00 help any?
Customer: replied 8 months ago.
Or p313731 or 124000
Expert:  sprinkles08 replied 8 months ago.

Nothing related there I'm afraid.
