My 2013 Honda Jazz/Fit has recently developed an issue where the ABS and TCS amber lights come on unexpectedly. These lights illuminate randomly while driving, but they turn off once the car is turned off. After restarting the vehicle, I can drive anywhere from a few miles to hundreds of miles before the lights come on again. I suspect there might be a faulty connection or an electrical problem causing this. Has anyone else experienced a similar problem and found a solution? Your insights would be greatly appreciated.

 

Dirty sensor and/or dented wheel could do that. Experienced it on my 00 Civic...

 

Codes should be stored in the TCS/ABS module despite the disappearances. Could be a number of issues, I'd start with a proper scan tool though, advance auto and autozone don't have proper ones. Go to a shop.

 

I did do scan and got fault code 790B "Unknown fault code". Anyone know what is that? I guess have to go to Honda official garage to get explanation for that because it seems its Honda's own fault code. Google doesn't give any answers.

Additionally got couple other fault codes: 92-20 and B1232
