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 when there is less than 3.0 volts present at the transmissioncontrol output circuits located in
the Powertrain Control Module (PCM) when the Transmission Control Systemrequest the power up of those
circuits.Note: Due to the integration of the Transmission Control Module and the Powertrain Control
Module, both systems have their own power and ground circuits..
Possible Causes
RELATED TIPM DTCS
(T515) TRANSMISSION CONTROL CIRCUIT SHORT TO GROUND
(T515) TRANSMISSION CONTROL CIRCUIT OPEN
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 the Transmission Control System detects less that 3.0 volts when
the output is commanded on, the DTC will set.Note: Inadequate Transmission Control Output voltage can also
cause DTCs P0846, P0869, P0871, P0876 or P0988 to set. Repairing the P0882 fault should also eliminate the
related DTCs.
Diagnostic Test

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.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

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 voltage on any of thepressure switch inputs prior to
the Transmission Control Output circuit being energized.
Possible Causes
PRESSURE SWITCH SENSE CIRCUITS SHORT TO 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 Totally Integrated Control Module (TIPM) replaces the Transmission control relay. The Transmission Control
Output circuit It is used to supply power to the solenoids and pressure switches (Transmission Solenoid/TRS
Assembly) when the transmission is in normal operating mode. When the Transmission Control Output circuit is off,
no power is supplied and the transmission.
Immediately after a controller reset (ignition key turned to the
runposition or after cranking engine), the TCM ver-
ifies that the Transmission Control Output circuits are open by checking for no voltage at the transmission control
output terminals at the PCM. After this is verified, the voltage at the pressure switches are checked. There should
be no voltage on the pressure switches at this time. The PCM will then activate the relay.
