Condition DTC P0747 may set in the TCM during engine shut-down when the transmission is in Park/Neutral without any hydraulic/mechanical concerns with the transmission. This DTC will be current at time of engine start-up and DTC will transition to History only after 6-7 upshift. Cause The concern may be that the BCM is not continuing to supply ignition voltage (within 4.0 volts of B+) to the TCM/ECM after engine running shut down to allow the modules to perform the power-down self test. If ignition voltage (within 4.0 volts of B+) is not present from the BCM connector X4, terminal 22, for a minimum of 15 seconds after the ignition is cycled o , the TCM/ECM modules will not complete the power down self test, and then during the next engine cranking (start-up) will see data from wherever the self test stopped, typically will see engine RPMs during cranking, and may set DTC P0747 in the TCM. Correction: With the Key On Engine OFF, disconnect the Keyless Entry Control Module (KECM) and verify ignition voltage is within 4.0 volts of B+ at the BCM connector X4, terminal 22. ** Note ** Use the VIN of the vehicle to locate the BCM schematic for circuit 5985 in SI : Power and Signal Distribution / Data Communications / Schematic and Routing Diagrams / Data Communication Schematics / High Speed GMLAN Communication Enable -- (May read Accessory Wake up). Inspect the TCM and ECM connector for possible terminal connection concern, and/or for possible open in circuit 5985 to the TCM and ECM. If no fault is found with circuit 5985, and/or no fault is found for a terminal connection concern at the BCM/ECM/TCM connectors, then replace and re-program the BCM. ** Note ** B+ voltage minus 4 volts variation. Example : if battery voltage is 12 volts then the circuit should never be below 8 volts. * This P/I will be updated or advanced to a TSB, if needed.
