Hi,
I spend some time searching for pictures/description of ABC front valve connections.
Which hydraulic line goes where (there are 6 in/outs) ?
There are also 3 electrical connectors - need to know proper fitting.
I have few pictures from WIS, but there is like overview - no detailed picture telling that e.g. front left strut is connected to A connector at valve block

If you have your own photos please share.

Year ago indy repaired broken ABC pipe from tandem pump to front valve and after that I don't like ABC in my car. Is very hard on small stones on the road etc. I feel like struts in normal mode are over pressured.
I want to check/compare if mechanic connected proper lines to front valve block.

Hi/Lo works with no issues.
No any oil leaks.
Rodeo passed with no errors.
New pulsation dumper on tandem pump, new front and rear pressure accumulators.

Dealer after DAS tests had no clue. One idea (but no any errors) are high sensors ?

Thank you,
Mariusz

abc shocks with age get their oil orifices plugged a bit resulting in stiffer ride. this is common abc "trait".
