Important: Either the technician or the service advisor should question the customer
about the sequence of events that led to the failure. A defining point would be if the
customer states they were unable to shut the vehicle down and that led to a dead battery.
This would more than likely point to a drifted park position. Qualifying the sequence of
events would be very helpful in the diagnostics.
Some customers may comment on one or more of the following conditions:
• Dead battery
• No Start
• Vehicle will not shut down
Technicians may find one or more of the following DTCs set:
• U0402
• U0422
• U1611
• U0101
• U0209
• U3002
• U1008
• U0073
• P07E6
• P18E7
• P17F6
• P1961
• P1964
• P0652
• P284F
• P1789
• P0562
This condition may be caused by park sensor drift or communication error, caused by
module or circuitry.

The technician is advised to start a TAC case immediately and forward the park sensor
measurement found in GDS transmission data.
Correction

The TAC agent will use this data to request that engineering verify the park position at
birth. Comparison of this data will confirm whether the transmission has park sensor drift
that will require transmission replacement, or the correct direction of vehicle repair.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
