For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on. Battery voltage greater than 10 volts.Set Condition:An overcurrent condition is detected in the TCM Power Control circuit. One Trip Fault. Three good trips to turn off the MIL.Possible CausesTRANSMISSION SOLENOID/TRS ASSEMBLYPOWERTRAIN CONTROL MODULE (PCM)TOTALLY INTEGRATED POWER MODULE (TIPM)1. CHECK IF THE DTC IS ACTIVEIgnition on, engine not running.With a scan tool, read TIPM DTCs.Is the DTC active at this time?YesGo To 2NoGo To 52. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT

Turn the ignition off to the lock position.Disconnect the TIPM C2 harness connector.Connect the positive probe of an ammeter to battery positive and connect the negative probe to the (T16) Transmission Control Output circuit in the TIPM C2 harness connector.Read the amperage on the ammeter.Does the amperage read below 2.0 amps?YesGo To 4No Go To 33. CHECK THE PCM

Disconnect the ammeter from the TIPM C2 harness connector and battery positive.Disconnect the PCM C4 harness connector.Reconnect the positive probe of an ammeter to battery positive and connect the negative probe to the (T16) Transmission Control Output circuit in the TIPM C2 harness connector.Read the amperage on the ammeter.Does the amperage read below 2.0 amps?YesUsing the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the PCM per the Service Information. With the scan tool, perform QUICK LEARNPerform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoGo To 44. CHECK THE TRANSMISSION SOLENOIDS

Disconnect the ammeter from the TIPM C2 harness connector.Disconnect the PCM C4 harness connector and install Miller tool #8815.Connect the positive probe of an ammeter to battery positive and connect the negative probe to the (T16) Transmission Control Output circuit in the TIPM C10 harness connector.While monitoring the amperage reading of the ammeter and using a jumper wire, jump each solenoid control circuit to ground one at a time in the appropriate terminals of Miller tool #8815.The amperage draw should be approximately .02 milliampere on each solenoid circuit with the PCM C4 harness connector disconnected.Does the amperage read between .05 and .015 milliampere (±.005 milliampere) on each solenoid tested?YesReplace the Totally Integrated Control Module per the Service Information.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoReplace the Transmission Solenoid/TRS per the Service Information. Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)5. INTERMITTENT WIRING AND CONNECTORSThe conditions necessary to set the DTC are not present at this time.Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.Wiggle the wires while checking for shorted and open circuits.Were there any problems found?YesRepair as necessary.Perform 545RFE TRANSMISSION VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)NoTest Complete.
