TCM P1781 code?

[Biodiesel6.6]

I used EFILive and scanned for DTC and came up with a P1781 code which listed it as Engine Torque signal circuit. Any idea what this could be from or upcomming problems? :confused:

DTC P1781 indicates that the ECM is detecting an incorrect voltage level on the TCM MIL (Malfunction Indicator Lamp) request circuit.

The TCM MIL request circuit path is between TCM connector-C1 pin-25 (DK BLU wire) and ECM connector-C2 pin-53.

May need to spend some time with a DVM if it repeats after clearing DTC's. smile.gif
