- Inspect the Wiring: Carefully examine the wiring leading to the OBD2 port. Look for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wires.
- Test the DLC: Using a multimeter, check for power and ground at the OBD2 port. This will confirm if the DLC is receiving power.
- Check for Communication Errors: If you have access to a working OBD2 scanner, try connecting it to another vehicle. If the scanner works on another vehicle, the problem lies within your Escalade.
Advanced Troubleshooting
If the basic steps don’t solve the problem, consider these more advanced options:
- ECU Reset: Disconnecting the battery for a few minutes can sometimes reset the ECU and resolve communication issues. However, be aware that this might erase some stored settings.
