right rear line had a small leak at inlet line repaired, still not working. I jump relay at 87 to get pump to work then with my snap on scanner get right front left front or left rear to open and allow air in and raise vehicle but nothing on rear right. I back prob voltages and all six wires leading to rear valves have full twelve volts, when I turn left rear valve unit on voltage on the yel/grn wire drops to 5v which I believ to be normal when I do same to right rear yel/gry wire its drops to .03 volts ? fyi that's back probed at 6way connector under car as well as on unit control under passenger floor plate. I'm wondering is the valve unit on right rear bag faulty and drawing the xtra volts or is it simply the control unit

I can jump pin 87 for power and pump runs fine,i can get each corner to function but only with hand held scanner, now right rear makes louder tyen other 3 corners when activated and still wont allow air in, if one corner malfunctions is it possible it will feed back and turn system off?

finally received parts and got this baby working. at end of day this is the series of what happened with this cls.....a little over a year ago right rear bag got punctured and failed, another shop decide to put an aftermarket one on that side only even though manufacture clearly states re4place in pairs, a leak developed in right rear line causing pump to over run and loose strength, I replaced as a pair on rear bags and replaced faulty pump, returned oem bag to customer that sold it on eBay .
my customer is now happy and is spreading the news which is great for my shop.
