Freightliner WABCO ECAS retrofiting

Hi.

Today I started ECAS on my Century Class retrofiting.

I installed ECAS solenoid valve on rear crossmember, wired level sensor and valve, put ECAS unit on data logger place and tested all system.

I did level calibration and did to errands.

I cant understand how are this things related, but truck runs much smoother, especially bobtailig.

The project is not done, becouse no ECAS warning lamps and no ECAS diagnostic link (I connected interface directly to ECAS unit).

 

ECAS - electronically controlled air suspention.

There is control unit in cabine, level sensor and solenoid valve.

I got all parts from MAN and DAF trucks (used of course)

Now I got the simplest ECAS configuration and later I wanna add load indicator and convert system to 2 sensor system, left and right to reduce roll risk.

I got no used 12V control units so I put 12-24V converter.

 

yeah, some European things in US truck now
