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.

POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Diagnostic Test
1.CHECK THE WIRING AND CONNECTORS
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.
NOTE: Due to the integration of the Powertrain and Transmission Control Modules, the transmission part of
the PCM has it’s own specific power and ground circuits.
Wiggle the wires while checking for shorted and open circuits.
Check for any Service Bulletins that may apply.
Were there any problems found?
Ye s>>
Repair the power and/or ground circuits as necessary.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The T1, T2, T3, T41, or T42 (C1 - C5) Sense circuits communicate the shift lever position to the Transmission
Control System. Each circuit is terminated at the transmission by a switch(TRS). Each switch can be either 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 it own unique combination of closed and open switches. This is called a PRNDL code.
There are 5 switches, therefore: there are many possible combinations of open and closed switches (codes). There
are 12 valid codes: two for neutral, one for each other gear position (5), and five temporary (transition zone) codes.
The remainder of the codes should never occur, these are called invalid codes.
Diagnostic Test
1.CHECK TO SEE IF P0706 DTC IS CURRENT
With the scan tool, perform the Shift Lever Position Test.
Select the test outcome from the following:
Test passes:
Go To 6
Test fails with Error Code:
Go To 2
Test fails without Error Code:
Perform the Gearshift Adjustment Procedure per the Service Information.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
2.CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY
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 Transmission Simulator, Miller tool #8333.
Ignition on, engine not running.
With the scan tool, perform the Shift Lever Position Test.
