When Monitored:
When the ignition is turned from
OFFposition toRUNposition and/or the ignition is turned fromSTART
position toRUNposition.
Set Condition:
This DTC is set if the Powertrain Control Module senses greater than 3.0 volts on the Transmission Control
Relay Output circuits prior to a request from the PCM to TIPM to energize theTransmission Output circuits.
Possible Causes
TIPM DTCS PRESENT
(T15) TRANSMISSION CONTROL CIRCUIT SHORT TO VOLTAGE
(T16) TRANSMISSION CONTROL OUTPUT CIRCUIT SHORT VOLTAGE
TRANSMISSION SOLENOID/TRS ASSEMBLY
POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The Transmission Control Output circuit is used to supply power to the Transmission Solenoid/TRS Assembly and to
the PCM when in normal operating mode. The purpose of the Transmission Output circuit is to allow the Transmis-
sion Control System to turn off the power to the Transmission Solenoid/TRSAssembly in event that the transmission
should need to be placed into “limp-in” mode due to a DTC.
After a PCM reset, (ignition switch turned to the run position, or after cranking the engine) the Transmission Control
System verifies that the Transmission Output circuit is open by checking for voltage on the Transmission Output
circuits before the Transmission Control System request for the circuit to be powered up. The request is sent by a
direct circuit control from the PCM tothe TIPM. If voltage is detected on the Transmission Output circuits before the
request is sent, the DTC will set.
Diagnostic Test
1.CHECK FOR TCM TIPM DTCS
With the scan tool under TIPM, check for TCM Power Input DTCs.
Are there any TIPM TCM Power Input DTCS present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom.
No>>
Go To 2
2.CHECK TO SEE IF DTC P0883 IS CURRENT
With the scan tool, check the STARTS SINCE SET counter.
NOTE: This counter only applies to the last DTC set.
Is the STARTS SINCE SET counter set to 0?

3.(T16) TRANSMISSION OUTPUT CIRCUIT SHORT TO VOLTAGE
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector and connect Miller tool
#8815.
Disconnect the TIPM C10 harness connector.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller tool #8815 to per-
form diagnosis.
Ignition on, engine not running.
Measure the voltage of the (T16) Transmission Control Output circuits in
the Miller tool #8815.
Is the voltage above 0.5 volts on any (T16) Transmission Con-
trol Output circuit?

4.CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
Turn the ignition off to the lock position.
Disconnect the Transmission Solenoid/TRS Assembly harness connec-
tor.

5.CHECK THE (T515) TRANSMISSION CONTROL CIRCUIT FOR A SHORT TO VOLTAGE
Measure the voltage of the (T515) Transmission Control circuit.
Is the voltage above 0.5 volts?

When Monitored:
When Powertrain Control Module initially powers up. Due to the integration of the Powertrain and Transmission
Control Modules, the transmission part of the PCM has its own specific power and ground circuits.
Set Condition:
This DTC will set if the PCM powers up and senses the vehicle in a valid forwardgear,withnoPRNDLDTCs,
and an output speed above 800 RPM, approximately 32 Kmh or 20 mph.
Possible Causes
POWER UP AT SPEED
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
If a vehicle loses power to the Transmission Control System, the solenoids(LR, 2C, OD, UD, 4C) will go to their
respective power off state. Some solenoids are normally vented and some are normally applied in their power off
state. The transmission is designed to be in 3rd gear with all of the solenoids in this state. However, if power is
restored, the Transmission Control System will power-up and normal operation will be restored.
This code identifies that power to the Transmission Control System was restored when the gear selector was in a
Driveposition while the vehicle was moving at speeds above 32 Kmh (20 mph).This DTC does not indicate a
problem with the transmission or Transmission Control System,instead, it suggests intermittent problems in
the fused ignition switch output, fused B(+), or ground circuits to the TCM. Alternately, if a person performs a rolling
restart maneuver, the DTC can be set. Therefore it is critical that this DTCbe investigated if the vehicle is experi-
encing intermittent 3rd gear operation and a subsequent return to normal operation.
Diagnostic Test
1.CHECK THE POWER AND GROUND CIRCUITS
This DTC is set when the Transmission portion of the Powertrain Control Module is initialized while the vehicle is
movingdowntheroadinavalidforwardgear.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
NOTE: Due to the integration of the Powertrain and Transmission Control Modules, the transmission part of
the PCM has its own specific power and ground circuits.
Check all of the Fused B(+), Fused Ignition Switch Output, and ground circuits to the PCM for an intermittent open
or short to ground.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
View repair.
Repair
Check all power and ground circuits to the PCM and repair as necessary.
