For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on. Battery voltage greater than 10 volts.Set Condition:A shorted condition is detected in the TIPM Transmission Control Output circuit.Possible Causes(T16) TRANSMISSION CONTROL OUTPUT CIRCUIT SHORT TO VOLTAGETOTALLY INTEGRATED POWER MODULE (TIPM)1. CHECK IF THE DTC IS ACTIVEIgnition on, engine not running.With the scan tool, read TIPM DTCs.Is the status Active for this DTC?YesGo to 2 NoGo to 42. (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT SHORT TO VOLTAGE

Turn the ignition off to the lock position.Disconnect the TIPM C2 harness connector.Disconnect the PCM C4 harness connector.Ignition on, engine not running.Measure the voltage of the (T16) Transmission Control Output circuit.Is the voltage above 10.0 volts?YesRepair the (T16) Transmission Control Output circuit for a short to voltage.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoGo to 33. TOTALLY INTEGRATED POWER MODULEUsing the schematics as a guide, inspect the wire harness and connectors.Check the TIPM harness connector terminals for corrosion, damage, or terminal push outPay particular attention to all power and ground circuits.Were there any problems found?YesRepair as necessary.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoReplace the Totally Integrated Power Module per Service Information.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)4. INTERMITTENT WIRING AND CONNECTORSThe conditions necessary to set this DTC are not present at this time.Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.Look for the data to change or for the DTC to reset during the wiggle test.Were any problems found?YesRepair as necessary.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoTest complete.
