Hello all,

One morning, I tried to start my E84; it cranked but did not start. I ran a diagnostic with ISTA and found no communication with the DDE. I tested both relays under the hood, and they are okay.

Next, I measured the voltage on the DDE connectors, but I never got 12V. Consequently, I checked the terminal 30 of the blue relay coil (K2003A) and found no 12V at any time.

The next step I want to take is to try running a manual 12V cable to my coil to close the contact and see if this allows me to power my DDE.

Do you have any suggestions for me?
