Wiggle the Caddy Connection

This bulletin applies to 2010-2013 Cadillac SRX and 2013 ATS models. Multiple DTCs may be set and instrument panel Self-Test/WOW occurs when the MDI is plugged into the vehicle’s DLC (diagnostic link connector).

The condition may be aggravated by slightly wiggling the connection at the DLC. This can be caused by a poor electrical connection to the MDI caused by spread terminals in the DLC. Most frequently, DLC ground terminals 4 and 5 are the culprit, but it could be the positive connections as well.

Use diagnostic test probe J-35616-2A (GY) to test for spread terminals. If replacement terminals are required, they are part number 50420-8000 and are located in tray 15 of the terminal repair kit.
