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.

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

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.

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.

Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

When Monitored:
Continuously with the ignition on.
Set Condition:
The DTC will set if the controller detects an invalid PRNDL code which lastsfor more than 0.042 seconds.
Possible Causes
SHIFTER OUT OF ADJUSTMENT
TRS SENSE CIRCUIT OPEN
TRS SENSE CIRCUIT SHORT TO GROUND
TRS SENSE CIRCUIT SHORT TO VOLTAGE
METAL DEBRIS IN OIL PAN
TRANSMISSION RANGE SENSOR
POWERTRAIN CONTROL MODULE
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The C1 through C4 (T1, T3, T41, and T42) sense circuits communicate the shift lever position to the PCM. Each
circuit is terminated at the transmission with a switch. Each switch can beeither 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 a certain combination of switches, which will be open and closed, this is called a PRNDL code. There
are 4 switches, therefore: there are many possible combinations of open and closed switches (codes). However,
there are only 9 valid codes (8 for AutoStick), one for each gear position and three recognized between gear codes.
The remainder of the codes should never occur, these are called invalid codes. The following chart shows the nor-
mal switch states for each shift lever position.
