OBD Port no power 98 v70xc

Post by Bdates » Mon Jan 21, 2019 5:15 pm

My OBD2 port used to work and now it doesn't. It is not my scanner because it still works on my wife's escape. Any ideas?

Head up to the sticky which helps locate wiring diagrams, find yours, and start tracing back to from the port.

On ME7 it is fused right off the main power buss, but your 1998 might be different
