Coding c0691 damper control relay range circuit with the service active handling and traction control flashing on dash.
How do yo go about testing suspension control module? I have tested relay circuit and found no opens or shorts. The ABS module was just replaced and no longer getting code for that.

Hi,

Here is the test for this code and the description as to what is happening.

Looks like the test says the RTD relay, wiring, or the ESC module could be the issue. However, run through the test and see what you come up with.
