P128E-TCM POWER CONTROL CIRCUIT 2 OVERCURRENT - TIPM
For a complete wiring diagramRefer to Section 8W.

When Monitored:
With the ignition on. Battery voltage greater than 10 volts.
Set Condition:
An overcurrent condition is detected in the Transmission Control Output circuit. One Trip Fault. Three good
trips to turn off the MIL.
Possible Causes
SOLENOID/PRESSURE SWITCH ASSEMBLY
ENGINE CONTROL MODULE (ECM)
TOTALLY INTEGRATED POWER MODULE (TIPM)
Diagnostic Test

Ignition on, engine not running.
With a scan tool, read TIPM DTCs.
Is the DTC active at this time?
Ye s>>
Go To 2

Go To 5
2.CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT
Turn the ignition off.
Disconnect the TIPM C10 harness connector.
Connect the positive probe of an ammeter to battery positive and con-
nect the negative probe to the (T16) Transmission Control Output circuit
in the TIPM C10 harness connector.
Read the amperage on the ammeter.
Does the amperage read below 2.0 amps?

P1740-TCC O/D SOL PERFORMANCE (DIESEL)
For a complete wiring diagramRefer to Section 8W
Theory of Operation
The Torque Converter Clutch (TCC) Solenoid is used to engage the TCC which improves fuel economy.
When Monitored:
The Torque Convertor Clutch (TCC) and Overdrive Clutch (O/D) will be tested each time the ECM requests
TCC engagement in 3rd gear and O/D.
Set Condition:
The DTC will set if the expected RPM drop is not achieved while attempting toengage TCC or O/D. This
indicates a malfunctioning torqueconvertor or overdrive clutch.
Possible Causes
ENGINE DTCS PRESENT
TRANSMISSION DTCS PRESENT
TRANSMISSION TEMPERATURE TOO COLD
OIL PAN CONTAINS EXCESSIVE DEBRIS
3-4 SHIFT SOLENOID
SHAFT OR SEAL DAMAGE
TCC SOLENOID
TORQUE CONVERTER
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)
