2006 DODGE RAM SRT-10 wiring diagram

P0122-TPS/APP CIRCUIT LOW
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
This DTC will set if the monitored TPS voltage drops below .078 volts for theperiod of 0.48 seconds.
Possible Causes
RELATED TPS ENGINE DTCS PRESENT
POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The powertrain controller receives the throttle position signal from theThrottle Position Sensor (TPS). The controller
provides the TPS with a 5 volt pull up and a sensor ground. The signal is checked for being out of range as well
as for intermittent operation (excessive signal changes). The engine controller transmits the throttle value onto the
Bus. Most engine controllers will calculate the throttle value if the throttle signal is lost. If an error is detected by the
transmission controller and the throttle value is available on the Bus, the Bus value will be used, normal operation
will continue, and a TPS code will be set. If an error is detected and the throttle value is not available on the Bus,
normal operation will be discontinued, a TPS DTC will be set, and the MIL will be turned on after 5 minutes of
calculated operation.
Diagnostic Test
1.DETERMINING IF RELATED ENGINE TPS DTCS ARE PRESENT
With the scan tool, check Engine DTCs, including pending DTCs and one trip failures.
Are there any Engine TPS DTCs present?
Ye s>>
Refer to the Driveability category and perform the appropriate diagnostic procedure.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

2.CHECK IF THE DTC IS CURRENT
With the scan tool, record the DTC EVENT DATA to help identify the conditionsinwhichtheDTCwasset.
With the scan tool, erase Transmission DTCs.
NOTE: To erase EVENT DATA information, a BATTERY DISCONNECT must be performed. Performing a BAT-
TERY DISCONNECT will reset all learned Transmission values to controllerdefaults which may lead to
erratic shift schedules.
Drive the vehicle and try to duplicate the conditions in which the DTC was reported by the DTC EVENT DATA.
With the scan tool, read Transmission DTCs.
Does this DTC reset?

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.

P0218-HIGH TEMPERATURE OPERATION ACTIVATED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Whenever the engine is running.
Set Condition:
Immediately when a Overheat shift schedule is activated when the Transmission Oil Temperature reaches 155°
C or 240° F.
Possible Causes
ENGINE COOLING SYSTEM OPERATION
TRANSMISSION OIL COOLER PLUGGED
H I G H T E M P E R AT U R E O P E R AT I O N S A C T I VAT E D
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
If the transmission oil temperature rises above 115° C (240° F), the overheat shift schedule is activated refer to
Transmission Operation as a function of Transmission Oil Temperature andthe code is set. The DTC is an infor-
mational code only and is being set to aid the technician in determining root cause of a customer driveability issue.
The code is also intended to alert the technician to determine if a cooling system malfunction has occurred or if an
additional transmission air to oil cooler should be added to the vehicle ifthe customer regularly drives in a manner
that overheats the transmission. Extended operation above 115° C (240° F)will reduce the durability of the trans-
mission and should be avoided. Correcting the cooling system malfunctionor installing an additional transmission oil
cooler will improve transmission durability especially for customers who operate in city/construction stop and go traf-
fic, tow trailers regularly, drive aggressively in low gear or drive regularly in mountainous areas.
Diagnostic Test

P0562-BATTERY VOLTAGE LOW
For a complete wiring diagramRefer to Section 8W.

P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Check for generic software is made at power-up.
Set Condition:
If generic software is found, the MIL will light immediately. This DTC is designed to signal the technician that
the controller still has generic software installed.
Possible Causes
PCM - PROGRAMMING ERROR
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The controller is programmed during manufacturing with generic softwareto facilitate testing. This software does not
have the proper calibrations to control a transmission in a vehicle. The check for generic software is made at power-
up. If generic software is found, the MIL will light immediately and the MILwill stay on even if the fault is cleared,
until the proper software is installed.Note:Transmissionwillbeplacedin limp-in mode.
Diagnostic Test
1.CONTROL MODULE PROGRAMMING ERROR
NOTE: Controller is programmed with generic software and will not allow the correct vehicle Powertrain
management.
Record the controller part number.

P0604-INTERNAL CONTROL MODULE RAM
For a complete wiring diagramRefer to Section 8W.
When Monitored:
One time after the ignition key is turned to the run position.
Set Condition:
The read value does not match the written value in any RAM location.
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
After the controller is reset, the microprocessor checks the integrity ofeach RAM location by writing to it and read-
ing back from it. The read value should be the same as the written value. MIL on after 10 seconds of vehicle oper-
ation and transmission will be placed in limp-in.
Diagnostic Test
1.PCM - INTERNAL ERROR
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.

TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

P0605-INTERNAL CONTROL MODULE ROM
For a complete wiring diagramRefer to Section 8W.
When Monitored:
One time after the ignition key is turned to the run position.
Set Condition:
If the ROM checksum does not match a known constant.
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
After the controller is reset, the microprocessor checksthe integrity ofthe program memory (ROM). A checksum is
calculated by adding all used bytes in the program memory. The sum should bethesameasaknownconstant
stored in memory. MIL on after 10 seconds of vehicle operation and transmission will be placed in limp-in.
