Warning lights: ABS, T/C & ESP/BAS spontaneously flashed up?

Like any other computer, "Have you tried turning it off & on again?"

If they stay on after that & a short drive, there is something else.

Installing a main battery isolator makes this such an easy task.
Make sure it is a quality HD one for the job though.
It's a very good safety initiative as well.

ABS Codes will not automatically clear themselves when you disconnect the battery.

Most ABS Systems will require a specific distance / time / starts etc without a fault to auto reset. So an intermittent problem may well cause extended periods of deactivation. Apparently their are also faults that aren't simply auto reset but require a scan tool ( not a generic reader ) to reset.

So when its fixed,it will take some time for it to self reset and even then the error codes will still be logged in the ABS units memory.

interesting. will be in my mind when the next faults pop up!

I have this error aslight come on after driving starts. I placed on scanner and it stated error C2200 also front LH and RH wheel sensors. Changed both sensors but light came back on and error C2200 is back. What do you think, is it the ABS module as stated by this code or should I change both rear sensors even though that error is not longer up?

Had this in February

Scan came up with passenger side front sensor fault.
Disconnected it drove OK until fitted new sensor, which didnt fix it.
Fault was a worn out front Hub bearing
Appeared to drive OK without issue apart from the light 'array'.
When on the lift both front hubs were found to be on their way out after 72,000 miles
So got both replaced which came with sensors already fitted & got 6 new bolts fitted whilst they were in there.
4+ hours of work
Suppose the 315/70/17 Duratracs I've had on for the last 3 years didnt help either.
