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.
UpdatethecontrollerwiththecorrectsoftwareinaccordancewiththeService Information.
Verify that the controller updated successfully.

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.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
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.
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.

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.
