Dodge Dakota (ND). Manual - part 1010

P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED

For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE -
SCHEMATICS 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 genic 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 - 45RFE/545RFE - 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

CONTROL MODULE PROGRAMMING ERROR

NOTE: Controller is programmed with generic software and will not allow the correct vehicle Powertrain
management.
With the scan tool.

Record the vehicles controller part number.

Select Use Controller Part Number under the Flash Tab.

Flash the controller with the correct software.

Verify the controller flashed successfully.

Test Complete

Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. Perform Quick Learn

SCHEMATICS AND DIAGRAMS).

For a complete wiring diagram Refer to Section 8W.

•

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.

Possible Causes

POWER OR GROUND CIRCUIT

POWERTRAIN CONTROL MODULE

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING).

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 should be same as value written.

Diagnostic Test

CHECK WIRING AND CONNECTORS FOR INTERMITTENT OPERATION

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?

Yes

>> Repair the power and/or ground circuits to the PCM and Transmission Control Relay as necessary.

Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1.

>> Replace the PCM per the Service Information. With the scan tool, perform QUICK LEARN.

SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING).

Theory of Operation

After the controller is reset (ignition turned to the RUN position) the microprocessor checks the integrity of the pro-
gram 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 the program memory.

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.

•

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 the too early - too late watchdog test.
2) The Transmission Control Relay remains on after the watchdog delay expired.

Possible Causes

POWER OR GROUND CIRCUIT

POWERTRAIN CONTROL MODULE

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING).

Theory of Operation

The internal Watchdog (WD) is a separate hardware circuit that continuously monitors the microprocessor. To insure
the proper operation of the EATX controller the watchdog must receive a signal from the microprocessor within a
specific time window (14ms ± 1ms) to prevent a system shutdown after a short delay (570ms). The microprocessor
periodically tests the WD’s ability to provide this shutdown function using a three phase test;

1) Send the signal too late > 15ms

2) Send the signal too early < 13ms

3) Delay test < 590ms

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 shutdown can occur.

Diagnostic Test

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.
