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
1.CHECK IF THE DTC P0882 IS CURRENT

NOTE: This counter only applies to the last DTC set.

When Monitored:
When the ignition is turned from

Relay Output circuits prior to a request from the PCM to TIPM to energize theTransmission Output circuits.

When Monitored:
When the ignition is turned from

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.

When Monitored:
Continuously with the ignition on, engine running, with the transmissionin gear.
Set Condition:
The PCM continuously monitors Actual Line Pressure and compares it to DesiredLinePressure.IftheActual
Line Pressure reading is more than 172.4 kPa (25 psi) higher than the Desired Line Pressure, but is less than
the highest Line Pressure ever used in the current gear, the DTC sets.
Possible Causes

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
Line pressure is electronically controlled by the Transmission Control System and is measured by the Line Pressure
Sensor (LPS). The desired line pressure is continuously being compared tothe actual line pressure and is regulated
by electronically changing the dutycycle of the Pressure Control Solenoid (PCS). (5% duty cycle = solenoid off =
max line pressure, 62% duty cycle =solenoid on = min line pressure).
The Transmission Control System calculates the desired line pressure based on inputs from the transmission and
engine. A calculated torque input to the transmission is used as the primary input of the desired line pressure cal-
culation and is called Torque Based Line Pressure. In addition, the line pressure is set to a preset level 827 to 931
kPa (120 to 135 psi) during shifts and in Park and Neutral to ensure consistent shift quality.
Diagnostic Test
1.DETERMINING IF RELATED DTCS ARE PRESENT
With the scan tool, check for other transmission DTCs.
Are there any other line pressure related DTCs present?

degree of 15°.
