Unsuccessful Programming Recovery

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

In the event of an interrupted or unsuccessful programming event, perform the following steps:

  1. DO NOT turn the ignition OFF. Ensure that all ECU, DLC and programming tool connections are secure and the TIS terminal operating software is up to date.
  2. Attempt to reprogram the ECU.
  3. If the ECU can still not be programmed, turn the ignition OFF for at least one minute.
  4. Turn the ignition ON and attempt to reprogram the ECU. The ECU should program.
    • If the ECU still cannot be programmed, replace the ECU.
