Hello! My name is***** am so sorry you have not been helped yet. Would you still like some assistance?
Do you have a scan tool?
looks like either the ECM went out or the TCM went out
I will give you to test procedure but may require scan tool
also, do you see the check engine light come on when you put key on engine off bulb test?
1. Install a scan tool and check for communication with as many modules as the scan tool will support and note what trouble code is stored in what control module.2. If the communication is isolated to the Transmission Control Module (TCM), turn the key off and disconnect. Using an ohm meter, measure across terminals.3. At the TCM, measure across terminals 37 and 38 and expect 120 ohms. Measure across terminals 6 and 7 and expect 120 ohms.4. Verify power and grounds are adequate at the TCM. If the tests pass, replace the TCM.
1. Remove the glove box and the right side close out panel under the Instrument Panel (IP).2. Locate the Vehicle Communications Interface Module (VCIM) right of the glove box.3. Verify all the connectors at the module.4. Place an ohmmeter between pins 14 and 6 of the DLC. A correct resistance value will be 60 ohms +/- 10%.5. Pull, tug and wiggle all harnesses and connectors at each of the modules on the High Speed LAN Network.
