When I first got my current ride .... was damn lazy. Decided to spend some $$ and had the car inspected by a WS. WS said other than some wear and tear .... all is well. So I bought the ride.
Not long after - I had some trouble with the steering. The ride came with active front steering and it wasn't working as it should. At high speed, it would twitch at some bends.
AFS is for assisting you in turns and changes turning rate at different speeds e.g. for safety at high speeds (more direct) and so you would not work up a sweat while parking (less number of turns).
Finally this error came up .........

Decided that I am close enough to home - drove carefully back. Picked up my obd cable and laptop then went back to the car. When I restarted the ride, the DSC light came on as well. Thinking about the twitching and the DSC error coming on as well - not surprising since the DSC relies on the AFS for some of its functions. I figured that the calibration of the AFS is probably out. So I decided to re-calibrate the AFS.
With the engine running (I need the power steering) - plugged in the cable and ran the diags. Was feeling moody so decided to use the simplest tool versus ISTA etc which is a pain to load up.
- Cleared all the errors
- Parked on a "nice" level ground
- Lined the steering angle to zero guided by the angle sensor (SZL). Quite a tedious process as it keeps "running".
- Initiate the calibration. The interesting part is when you had to jiggle the steering wheel like PCC as watch the motor
positions being calculated on screen.
- Turned off then on the engine
Watched the car boot up and the DSC error showed up. Cleared that error and restarted. Both the steering and DSC stayed off, finally. Btw, this is one of the things I would check before going for an alignment. And during alignments, make sure you choose the specifications that includes AFS.
And so I thought all is well till I did something and the ABS light came on a couple of days later .........
