reset DODGE RAM SRT-10 2006 Service Service Manual

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

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:
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.
Possible Causes
(T47) 2/4 PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE
(T50) L/R PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE
(T9) OD PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE
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 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.
Diagnostic Test

P0897-TRANSMISSION FLUID DETERIORATED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Each transition from full EMCC to partial EMCC for A/C bump prevention.
Set Condition:
DTC set if 20 occurrences of a turbine acceleration sum. Fault Set Time: 20 transitions from full EMCC to
partial EMCC. Transmission will not use partial EMCC. Established for A/Cbump prevention.
Possible Causes
WORN OUT/ BURNT TRANSAXLE FLUID
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
To prevent a bump due to A/C clutch engagement, a temporary torque converter partial EMCC condition is estab-
lished prior to A/C clutch engagement. A message is received over the bus indicating that A/C clutch engagement
is imminent. Partial EMCC is then established and a reply message,
OK to engage A/C clutchis sent via the bus.
Partial EMCC will be held for 450 ms before returning to full EMCC. During the transition from full to partial EMCC,
a turbine acceleration sum is calculated, if this value exceeds a threshold value for several transitions, degraded
transmission fluid is indicated.
Diagnostic Test
1.WORN OUT/ BURNT TRANSMISSION FLUID
Turn the ignition off to the lock position.
Flush the Transmission Oil Cooler and lines, replace the Transmission OilFilter, refill with new Transmission Fluid,
start the engine, and adjust the fluid per the Service Information.
NOTE: The Transmission Cooler must be flushed before proceeding.
Allow the engine to idle for 10 minutes, in Park.
Turn the ignition off to the lock position.
Again, flush the Transmission Oil Cooler and lines, replace the Transmission Oil Filter, refill with new Transmission
Fluid, start the engine, and adjust the fluid per the Service Information.
With the scan tool, perform a Battery Disconnect.
NOTE: The Battery Disconnect must be done to re-enable EMCC during an A/C Clutch engagement.
NOTE: The vehicle may exhibit intermittent shudder during the first few hundred miles. The new Transmis-
sion Fluid will gradually penetrate the Torque Convertor Clutch frictionmaterial and the shudder should
disappear.
Erase the DTC and return the vehicle to the customer.
Did the DTC reset and/or does the vehicle still shudder after a few thousandmiles?

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

LINE PRESSURE CONNECTOR AND WIRING
INTERNAL TRANSMISSION
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
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
