When Monitored:
Whenever the engine is running.
Set Condition:
The DTC is set if one of the pressure switches are open or closed at the wrong time in a given gear. If the
problem is identified for 3 successive key starts, the transmission will go into Limp-in mode and the MIL will
turn on after 10 seconds of vehicle operation.

Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The Transmission system uses three pressure switches to monitor the fluidpressure in the LR, 2/4, and OD ele-
ments. The pressure switches are continuously monitored for the correct states in each gear. Normal operation will
be experienced if no other codes are present. Transmission Control Systemwill ignore the code. Limp-in condition
will only occur if DTC P0871 is present with a DTC P0706.

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 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - 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, or P0871 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:

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

One time after a reset (ignition key turned to the RUN position or after cranking engine).
Set Condition:
A fault is set if voltage greater than 4.5 volts is detected for 7 msec on any of the pressure switch circuits
before the relay is energized. The transmission is placed in Limp-In. The MIL is on after 10 seconds. of vehicle
operation.

Theory of Operation
The transmission relay is used to supply power to the solenoid pack when in normal operating mode and to turn off
power to produce transmission
limp-inmode. The relay output (which supplies power to the solenoid pack) is fed
back to the controller. It is referred to as SWITCHED BATTERY. After a controller reset (ignition key turned to the
RUN position or after cranking engine), the controller verifies that the relay contacts are open by checking for no
voltage on Switched battery line (transmission control relay output) before the relay is energized. After switched
battery is verified for no voltage, the voltage of each of the solenoid packpressure switches is also checked. Since
the solenoid pack is not powered up, there should be no voltage on any of the pressure switches.
