Thread: SLS problem doing my head in

Not to me

bridging the signal from one sensor to both inputs and leaving one sensor unplugged will keep the compressor running untill the SLABS gets the target height input so if you start with that with even level from the bumps both bags will get the air for the same time cos the height inputs for both sides are the same being from one sensor... corroborated with what i said before about voltage drop the level might be different than the normal cos one sensor's signal divided in two can be different than on one single circuit for the reasons i explained... better dont bother with this theory and fix the wiring issue somehow then calibrate it and IMO it will be good

By the way, when you jiggled the wiring did the action reached the sensor's connector too...cos most contact problems are within the connetors(as an analogy with the injector harness) that's why you can find these kits on the market: Discovery 2 SLS AIR Suspension Ride Height Sensors Harness Connector Repair KIT | eBay (read the description) so IMO better get one and hardwire the sensor to the SLABS input then IMO you'll be fixed for good

My thought is that the compressor will keep going until the height sensor says it's at the required height.
If the compressor is pumping into the left bag, the right will be going up only marginally so the compressor I think would actually end up blowing out the bag in some cases.

Example: Left bag inflates by 20mm, the right sensor might inherently go up 5mm and so it actually ends up inflating 4 times as much as it should?

Does that theory make sense?

Wont make it level, but will determine if it is the sensor or wiring that is causing grief.

Latest update.

I replaced the plug and about 100mm of wiring on the left hand sensor. Got a really good condition plug off a wreck.

So far it seems happy! Reading a lot higher than it previously was. I soldered all the connections, heatshrinked, then electrical taped the loom back up from protection.

Have since recalibrated but needs some fine tuning - it's surprisingly hard to find a flat surface around here!
