Dodge Dakota (ND). Manual — part 923
P0562-BATTERY VOLTAGE LOW (CONTINUED)
7.
POWERTRAIN CONTROL MODULE
Using the schematics as a guide, inspect the wiring and connectors. Repair as necessary. Pay particular attention
to all power and ground circuits.
Check for any Service Bulletins and S.T.A.R. ON-LINE for any possible causes that may apply.
If there are no possible causes remaining, view repair.
Repair
Replace the Powertrain Control Module per the Service Information. With the scan tool perform QUICK
LEARN then program Pinion Factor in the Front Control Module.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.
8.
INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set the DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wiring and connectors while checking for shorts and open circuits.
With the scan tool, check the EATX DTC EVENT DATA to help identify the conditions in which the DTC was set.
Were there any problems found?
Yes
>> Repair as necessary.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.
No
>> Test Complete.

P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED
For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - SCHE-
MATICS AND DIAGRAMS)
For a complete wiring diagram Refer 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 - DIAGNOSIS AND TESTING).
Theory of Operation
The controller is programmed during manufacturing with generic software to 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 MIL will stay on even if the fault is cleared,
until the proper software is installed. Note: Transmission will be placed in 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.
Update the controller with the correct software in accordance with the Service Information.
Verify that the controller updated successfully.
Test Complete
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1.

P0604-INTERNAL CONTROL MODULE RAM
For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - SCHE-
MATICS AND DIAGRAMS)
For a complete wiring diagram Refer 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 - DIAGNOSIS AND TESTING.
Theory of Operation
After the controller is reset, the microprocessor checks the integrity of each 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.

For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - SCHE-
MATICS AND DIAGRAMS)
For a complete wiring diagram Refer 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 - DIAGNOSIS AND TESTING).
Theory of Operation
After the controller is reset, the microprocessor checks the integrity of the program memory (ROM). A checksum is
calculated by adding all used bytes in the program memory. The sum should be the same as a known constant
stored in memory. MIL on after 10 seconds of vehicle operation and transmission will be placed in limp-in.
