Hello,
I haven't actually checked this. now that you write it has received some other error codes. I'll check the battery and ground

Don't forget to check and whilst you're at them, clean, the ground points at various location here and there too. WIS will tell you where they are and how you can check them.

I have checked the battery. It looks good, clean. I also measured it and got 70%. it is 756a out of 900a, according to the test is ok. after I just started the car. minus cable is very thin. is it original I tried putting an extra 25 cable there. warmed up the car, swerved and gassed 2 times. it went well. turned off anti-spin. gassed a little more and swung with a cable. ABC red light immediately. turned the car off and on again. the warning disappeared and it was possible to drive as usual raising and lowering. I have to keep checking ground and 30 feed someone wrote above.

I have checked all the sensors I can access and can see. checked battery, ground and abc module after ergat and bad connection. I plugging in an extra battery. after that the car went smoother in the chassis. no error codes when i went full throttle and turned right. Then went full throttle and turned left. then the codes came back. think about whether the abc module could be bad. before they were enough to barely touch the gas and turn a little, I got the error code. something current related they seem to be.
however, after I drive a lot and rodeo mode. then I have probably stressed the system too much. now the car sinks down after a while when I park the car. I changed the gaskets a few months ago in the valve block. could they be something else causing the car to sink?

Update?

Have y'all figured this out?? Having the same issue with my CL65 to a tee it seems. At this point even turning the ignition on it immediately gets all the codes, all the values for the level sensors and pressure sensor are at their max/min possible values which obviously isn't true. She's slammed :")
