Yeah probably time to cave and buy a Gap tool... then a new compressor [bawl]

Hi All,
Ive encountered an unusual problem. I recently had my car at an auto elec to wire in a compressor for offload driving (tire inflation), when I got car back, dash warnings indicated suspension fault. I had initially though they had bumped something under the dash.
The and suspension dropped. I restarted the car and this went away, temporarily. SO I managed to get home, only to plug in scanner to read for faults.
Fault indicated that the Front Left ride height sensor was not responding. SO I plugged in my X Lifter, this confirmed the front left corner wasn’t reading a ride height sensor. (See photo)
Naturally I replaced this sensor with a tested 2nd hand one. and Suspension continues to fault. SO assuming id been sold a dodgy sensor, i replaced it with a new one. Still same issue.
Suspension fault, Initially the HDC light in dash was red, and the illumination under the console switches was non existent. Now, im back to Yellow HDC dash light, and the console lights, until the ECU realises their still is an issue, and they turn off. The car is still sitting down and won’t raise.

Has anyone encountered this issue before? if so, how do i fix this?

Grab a wiring diagram.. Check the sensor for a power supply and earth return first. Check for blown fuses. Maybe the auto elec made a whoppsy on the install. Or hasn't plugged something back in

I reckon they've grabbed the nearest live wire and spliced into it, now the EAS thinks one of the sensors is faulty. Undo the wiring that the leccy has done and see if the problem persists.

So after some fault finding ... I found this issue.. Bloody 2nd hand ride height sensor was dodgy. I replaced this with a new one, reset codes, and boom.... car is back to life.... did momentarily flash a code of ride height module, but cleared that, and no dramas. Went for a drive and checked codes again.... all clear so far...
Thanks for the help guys..
