Powertrain Control Module: Testing and Inspection
ECM Backprobing
If the inspection for a particular code requires voltage or resistance checks at the ECM connectors, remove the right door sill molding. Pull the
carpet back to expose the ECM. Unbolt the ECM cover, and connect the backprobe sets and a digital multimeter as described below. Check the
system according to the procedure described for the appropriate code(s).
How to Use the Backprobe Sets
Connect the backprobe adapters to the stacking patch cords, and connect the cords to a multimeter. Using the wire insulation as a guide for the
contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire side until it comes in contact with terminal end of the
wire.
