2006 DODGE RAM SRT-10 ignition

P0123-TPS/APP CIRCUIT HIGH
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
Due to the integration of the Powertrain and Transmission Control Modulesthe New Generation Control Module III
will be referred as the Powertrain Control Module (PCM). The 4.7L V-8 Throttle Positioning Sensor (TPS) provides
the PCM with an input signal voltage that represents the throttle blade position of the throttle body. The TPS is
connected to the throttle blade shaft. As the position of the throttle blade changes, the output voltage of the TPS
changes.
The 5.7L V-8 Accelerator Pedal Position Sensor (APPS) is a linear potentiometer that provides the PCM with a
voltage signal proportional to the angle, or position of the accelerator pedal. The APPS signal along with inputs from
other sensors is used by the PCM to calculate the throttle plate position which is electronically controlled.
When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
This DTC will set if the monitored TPS voltage rises above 4.94 volts for theperiod of 0.48 seconds.

P0604-INTERNAL CONTROL MODULE RAM
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
After the controller is reset (ignition turned to the RUN position), the microprocessor checks the integrity of each
RAM location by writing to it and reading back from it. The read value shouldbe same as value written.
When Monitored:
One time after the controller is reset (ignition turned to the RUN position).
Set Condition:
Whenever the Powertrain Control Module (PCM) detects an internal controller problem.

P0613-INTERNAL TCM
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The internal Watchdog (WD) is a separate hardware circuit that continuously monitors the microprocessor. To insure
the proper operation of the Transmission controller the watchdog must receive a signal from the microprocessor
within a specific time window (14 msec ± 1 msec) to prevent a system shutdownafter a short delay (570 msec).
The microprocessor periodically tests the WD’s ability to provide this shutdown function using a three phase test;
1) Send the signal too late > 15 msec
2) Send the signal too early < 13 msec
3) Delay test < 590 msec
If the watchdog input signal arrives too early or too late, the Watchdog Fault line will go low and the watchdog delay
will start to time out. The delay will be reset by the correct timing of watchdog signal sent during subsequent oper-
ations.
The Delay Test checks the delay time out. The Delay Monitor line is pulled low, which forces the delay to start timing
out. At the end of the delay time the Transmission Relay will be turned off. The delay test, upon detection of the
relay turning off, will immediately turn the relay back on before shutdowncan occur.
When Monitored:
1) One time after the controller is reset (ignition turned to the RUN position) and every 60 seconds thereafter.
The Delay Test is executed after a reset only.
2) 2 seconds after an invalid test.
Set Condition:
If either of the following conditions occur 3 times:
1) The watchdog fault line remains high after the period has elapsed for thetoo early - too late watchdog test.
2) The Transmission Control Relay remains on after the watchdog delay expired.
