The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.
Condition/Concern:
Some Technicians may experience failed module programming or difficulty performing certain diagnostic procedures due to the ignition not being in the "Ignition On, Engine Off" mode. The above listed vehicles use a keyless access system with push button start.
Recommendation/Instructions:
To reach the "Ignition On, Engine Off" mode, press and hold the ACC/OFF portion of the Start/ACC/OFF mode button for 5 seconds with a valid keyless entry transmitter inside the vehicle and the transmission in park. Refer to eSI Document ID # 1430062 for STS, Document ID # 1460260 for XLR and Document ID # 1456344 for Corvette.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
