1. Will the vehicle start (If necessary, connect a battery charger and allow the battery to charge to a level sufficient to support normal vehicle operation)?
a. YES >>> Proceed to the next step

b. NO >>>> This service bulletin does not apply. Further diagnosis may be required.
NOTE:
It is important that no vehicle controls are activated and/or that no actions are taken which could interfere with then normal vehicle sleep/wake-up process while verifying the radio behavior.
3. Verify that the radio (Telematics Gateway) will power on by itself after the vehicle goes to sleep
a. Place the ignition into off/lock.
b. Open and then close the drivers door. Do not lock the doors, this will enable VIA (if equipped) and delay the bus sleep time.
