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
Repair as necessary.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

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.

Repair
Check all power and ground circuits to the PCM and repair as necessary.

SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

P1684-BATTERY WAS DISCONNECTED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Whenever the ignition is in the Run/Start position.
Set Condition:
This DTC will set whenever Powertrain Control Module is disconnected fromFused B(+) or ground. It will also
be set using the scan tool to perform a Battery Disconnect and/or Quick Learn procedure.
Possible Causes
BATTERY WAS DISCONNECTED
SCAN TOOL BATTERY DISCONNECT PERFORMED
PCM WAS REPLACED OR DISCONNECTED
QUICK LEARN WAS PERFORMED
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 PCM uses a battery backed RAM (Random Access Memory) is used to maintainsome learned values. When
the battery B(+) is disconnected, the memory is lost. When the B(+) is restored, this memory loss is detected by the
Transmission Control System. The DTC is set and the learned values are initialized to known constants or previ-
ously learned values from EEPROM (Electronic Erasable Programmable ReadOnly Memory). This results in the
reinitialization of some parameters.
Diagnostic Test
1.POSSIBLE CAUSES
This DTC is an informational DTC only.
This DTC is set due to a momentary loss of power and/or the ground circuits tothe PCM.
Below are a list of possible causes associated with this DTC.
