2004 - 2005 Cadillac XLR: Service Information: No Crank, PRNDL Inoperative
Owners of some 2005 Chevrolet Corvettes and 2004 - 05 Cadillac XLRs may experience a no-crank condition, with no codes in any module. The concern may be followed by an inoperative transmission range indicator (PRNDL). The Tech 2 will show the transmission range circuits are all reading high when any gear is selected.
Check for a loose or broken ground G402 at the right rear suspension cradle. See SI document 1495107.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
