DODGE RAM SRT-10 2006 Service Repair Manual When Monitored:
Initially at ignition on, then every 10 seconds thereafter. The solenoidswill also be tested immediately after a
gear ratio error or pressure switch error is detected.
Set Condition:
T

When Monitored:
Initially at ignition on, then every 10 seconds thereafter. The solenoidswill also be tested immediately after a
gear ratio error or pressure switch error is detected.
Set Condition:
Three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio or
pressure switch error.
Possible Causes
RELATED TIPM TCM POWER CONTROL CIRCUIT DTCS PRESENT
(T19) 2/4 SOLENOID CONTROL CIRCUIT OPEN
(T19) 2/4 SOLENOID CONTROL CIRCUIT SHORT TO GROUND
(T19) 2/4 SOLENOID CONTROL CIRCUIT SHORT TO VOLTAGE
TRANSMISSION SOLENOID/PRESSURE SWITCH ASSEMBLY
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
Four solenoids are used to control the friction elements (clutches). The continuity of the solenoids circuits are peri-
odically tested. Each solenoid is turned on or off depending on its currentstate. An inductive spike should be
detected by the PCM during this test. If no spike is detected, the circuit istested again to verify the failure. In
addition to the periodic testing, the solenoid circuits are tested if a gear ratio or pressure switch error occurs. In this
case, one failure will result in the appropriate DTC being set. The MIL willilluminate and the transmission goes into
neutral, if the DTC is set above 35 Kmh (22 mph), Limp-in mode when vehicle speed is below 35 Kmh (22 mph).
Diagnostic Test
1.DETERMINING IF RELATED TIPM TCM POWER CONTROL CIRCUIT DTCS PRESENT
With the scan tool, read TIPM DTCs.
Are there any TIPM TCM Power Control Circuit DTCs present also?
Ye s>>
Refer to the Transmission category and perform the appropriate diagnostic procedure.
No>>
Go To 2
2.CHECK TO SEE IF P0755 IS CURRENT
With the scan tool, view DTCs.
Is the status Active or is the STARTS SINCE SET counter set at 0 for this DTC?
Ye s>>
Go To 3
No>>
Go To 7
3.CHECK THE PCM AND WIRING USING THE TRANSMISSION SIMULATOR
Turn the ignition off to the lock position.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install the Transmission Simulator,Miller tool #8333 and the ElectronicTransmission Adapter kit.
Ignition on, engine not running.
With the scan tool, actuate the 2/4 Solenoid.
