TECHNICAL

Subject: Engine Air Filter Life Shows 0% After Battery Disconnect

Attention: This bulletin replaces PIP5605 and PIP5636. Please discard all copies of PIP5605 and PIP5636

Service Procedure

Note: This procedure only applies if the condition occurred after a battery disconnect. Vehicles beyond 6 months in service and greater than 10,000 mi/16,000 km may have a true need for air filter maintenance that is NOT related to this bulletin procedure.

Note: It is possible that the OnStar OTA update has been pushed to the vehicle and that the customer has missed or ignored on-screen prompts to install it. A typical symptom of any pending OTA update is that the radio will remain on for 30 seconds after the ignition has been turned off and the driver door opened. Do NOT decline the OnStar update. OnStar firmware CANNOT be installed via TIS2Web due to cyber-security policy.

1. Inspect the engine air filter.

1.1. If the engine air filter requires service, advise the customer of the needed maintenance. Air filter maintenance is not a warrantable service.

1.2. If clean (not restricted), proceed to steps 2-4.

2. Reset the DIC message.

2.1. In the DIC scroll to Air Filter Life > select Menu > Reset > Yes.
