How to adjust and reinstall the roll bar sensors?
Turn the mode selector to arretiert. Now loosen the switch assembly mounting bolt and position it so the tip of the switch just barely comes into contact with the covering on the control arm. Tighten the mounting bolt, return the mode selector to funktion, and lower the car. re: 1990 500SL Installed shocks & struts..Roll bar pops up now????
How do you check the roll bar on a car?
To check an axle switch, put its mode selector in the arretiert position. Drive the car to a speed of at least 6 MPH and apply the brakes fairly hard for a short stop. The roll bar should deploy. Lower the roll bar, return the mode switch to the funktion position, and repeat the preceding test for the other axle switch.
How do you test a roll bar limit switch?
The roll bar limit switches are electrically normally closed with their arms in the “funktion” position. To test a switch you unplug it and measure the resistance across the two terminals.
What should I do if my roll bar pops up?
If the roll bar pops-up, you should press the switch as if trying to raise the bar for several seconds until you hear a “click”. This re-engages the drive mechanism so that you can then lower it with the switch normally. I installed new shocks and struts yesterday.
