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
(T515) TRANSMISSION CONTROL CIRCUIT SHORT TO VOLTAGE
(T16) TRANSMISSION CONTROL OUTPUT CIRCUIT SHORT VOLTAGE
TRANSMISSION SOLENOID/TRS ASSEMBLY
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 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 Control circuit DTCs.
Are there any TIPM TCM Power Control circuit DTCS present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom.

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?

P0884-POWER UP AT SPEED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
One time after each controller reset. Note: the Transmission Control Module is integrated with Powertrain Con-
trol Module. The Transmission Control Module has separate powers and grounds specifically to its portion of
the PCM.
Set Condition:
This DTC will set if the PCM powers up and senses the vehicle in a valid forward gear (no PRNDL DTCs) with
a output speed above 800 RPM, approximately 32 Kmh or 20 mph.
Possible Causes
INTERMITTENT POWER AND GROUND CIRCUITS
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
If a vehicle loses power to the PCM, the vehicle will go to the 2nd gear mode since there is no power available to
control the transmission solenoids. However if power is restored, the PCMwill power-up and normal operation will
be restored. This DTC identifies that power to the PCM was restored when thegear selector was in a
Driveposi-
tion while the vehicle was moving at speeds above 32 Kmh (20 mph). If a customer shifts to Neutral and cycles the
ignition key and quickly shifts to
Drivewhile moving before the PCM comes out of its START ROUTINE, the DTC
can be set. Therefore it is critical that this DTC diagnosis repair procedure should only be used if the vehicle is
experiencing intermittent 2nd gear operation and subsequently a return to normal operation during normal driving.
The transmission will not be placed in Limp-in. This is an informational DTC to be used when attempting to diag-
nose an intermittent 2nd gear operation and subsequent return to normal transmission operation.
Diagnostic Test
1.CHECK THE POWER AND GROUND CIRCUITS
This DTC is set when the PCM is initialized while the vehicle is moving in a valid forward gear. This is usually
caused by a momentary loss of power to the Transmission portion of the PCM.
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 perform diagno-
sis.
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 related to the PCM for an intermit-
tent open or short to ground.
Perform a wiggle test on all wiring and connectors pertaining to the PCM while looking for shorted or open circuits.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If there are no possible causes remaining, view repair.
Repair
