Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
We just eliminated the electronic shocks on a Cadillac escalade the other day. We ended up having to wire in a 4 ohm resistor in the place of the harness on each shock that monitors the electric suspension. You would also have to find the suspension leveling sensor and disconnect or bypass it. Let me see if I can find some diagrams for the DTS.
This type of resistor should work on your system:
You will need 2 PER STRUT/SHOCK wire them together and 1 end to the 2 wire factory car wiring and the other to the other wire.
According to the GM schematic that should send a 1-3 ohm resistance signal to the BCM and turn off the warning indicator. It looks like the leveling sensor might not need to be messed with at all, but you would have to try and and find out.
It's popular to do this on the escalade, but it's not a very commonly performed swap on the DTS.
