2006 DODGE RAM SRT-10 automatic transmission

P0613-INTERNAL TRANSMISSION PROCESSOR
For a complete wiring diagramRefer to Section 8W.
When Monitored:
After the ignition key is turned to the run position and 60 seconds thereafter.
Set Condition:
Either of the following conditions occur 3 times in less than 590 milliseconds: The watchdog line remains high
after the watchdog test or the transmission relay coil is energized and remains on after the watchdog delay
expires.
Possible Causes
PCM - INTERNAL ERROR
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The internal watchdog is a separate hardware circuit which continuously monitors the microprocessor. To make sure
the transmission is operating properly, the watchdog must receive a signal from the microprocessor within a specific
time window. MIL on after 10 seconds of vehicle operation and transmissionwill be placed in limp-in.
Diagnostic Test
1.PCM - INTERNAL ERROR
Using the schematics as a guide, inspect the wiring and connectors. Repairas necessary. Pay particular attention
to all power and ground circuits.
If there are no possible causes remaining, view repair.
Repair
Using the schematics as a guide, check the Powertrain Control Module (PCM)terminals for corrosion,
damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Ser-
vice Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems
are found, replace the PCM per the Service Information. With the scan tool,perform QUICK LEARN.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

When Monitored:
Continuously with the ignition on.
Set Condition:
The DTC will set if the controller detects an invalid PRNDL code which lastsfor more than 0.042 seconds.
Possible Causes
SHIFTER OUT OF ADJUSTMENT
TRS SENSE CIRCUIT OPEN
TRS SENSE CIRCUIT SHORT TO GROUND
TRS SENSE CIRCUIT SHORT TO VOLTAGE
METAL DEBRIS IN OIL PAN
TRANSMISSION RANGE SENSOR
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 C1 through C4 (T1, T3, T41, and T42) sense circuits communicate the shift lever position to the PCM. Each
circuit is terminated at the transmission with a switch. Each switch can beeither open or closed, depending on the
shift lever position. The PCM can decode this information and determine the shift lever position. Each shift lever
position has a certain combination of switches, which will be open and closed, this is called a PRNDL code. There
are 4 switches, therefore: there are many possible combinations of open and closed switches (codes). However,
there are only 9 valid codes (8 for AutoStick), one for each gear position and three recognized between gear codes.
The remainder of the codes should never occur, these are called invalid codes. The following chart shows the nor-
mal switch states for each shift lever position.

When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
DTC will set when the transmission temperature does not reach a normal operating temperature within a given
time frame. Time is variable due to ambient temperature. Approximate DTC set time is 10 to 35 minutes. The
following are starting temperature to warm up times to set this DTC: starting temperature -40° C (-40° F) warm
up time 35 minutes, starting temperature -28° C ( -20° F) 25 minutes, starting temperature -6.6° C (20° F) 20
minutes, starting temperature 15.5 ° C (60° F) 10 minutes. When the fault isset, calculated temperature is
substituted for measured temperature, however the DTC is stored only after three consecutive occurrences.

TRANSMISSION TEMPERATURE SENSOR
POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
