Order of inspection
P0885 TCM Power Relay Control Circuit/Open High
The P0885 code means the control circuit of the transmission control module (TCM) power supply is open, so the component gets no current when it is commanded on. It can cause limp mode or erratic shifting. A disconnected connector, an open coil or a cut wire is the usual cause.
