ABC Issues After Replacing Struts Question
A friend with an 02 S55 had been driving w/ a leaky left rear strut & a white ABC message for a couple years. Yesterday, he finally got around & replaced both rear with pre-owned Mercedes struts & I helped him performing a rodeo to get all the trapped air out using the Foxwell NT530 scanner. After rodeo, I tried to clear all the error codes (faults in component right front, left front, right rear, left rear level sensors, calibration of the plunger travel sensors hasn't been successfully performed & critical vehicle level front left & rear right) & the white ABC message on his instrument's cluster. The scanner prompted it's cleared, however when it performed a re-scan, all these codes kept coming back. I told him to back out of the garage & drive around the neighborhood for 10, 15 minutes in hopes the ECU will reset & clear all the codes but it didn't work. One thing I want to mention is that, when he put the car in reverse, the white ABC message changed from white to red & the backend of his car raised all the way up, however when he shifted the car into drive, the car's rear end came back down to the normal ride height & the ABC message changed back to white. Now with the car in park & engine running, the ABC message changed back to red & the scanner still detected these same codes even though the car sits perfectly on all 4 corners so we don't know what to make of this.
All of these error codes are pointed to the plunger travel sensors & height level sensors so perhaps they've lost a point of reference & in need of re-calibration or may be his ABC module is bad? Any thoughts?
