Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 2029

•

When Monitored:
Every 7 msec with:
1) Engine speed greater than 500 RPM.
2) Battery voltage between 10 and 16 volts.

•

Set Condition:
CAN C bus messages are not received for 10 seconds.

Theory of Operation

The NGC controller communicates over the CAN C bus. The transmission controller continuously monitors bus
activity. The CAN C bus is also used to communicate transmission MIL status to the Engine Controller. If the Engine
Controller is unable to communicate with the Transmission Controller, a DTC will set and the Engine Controller will
illuminate the MIL.

Refer to 8-ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING for diagnostic pro-
cedures and for further possible causes.

42RLE - PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE

For a complete wiring diagram Refer to Section 8W.

Perform the following steps prior to any diagnostic procedure(s).

1. Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any

leaks and fill the transmission to the proper fluid level. Refer to the Service Information for the proper repair and
fluid fill procedures.

2. Testing should only be performed with the battery fully charged to avoid false diagnosis.

3. With the scan tool, read Engine (PCM) DTCs. If Engine DTCs are present, refer to the Driveability Category and

perform to the appropriate diagnostic procedure(s) before proceeding.

4. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information.

Diagnose any Pending DTC as a matured DTC.

5. With the scan tool, read DTC EVENT DATA. Use this data to identify the conditions in which the DTC was set.

Note: Performing a Battery Disconnect will clear all DTC EVENT DATA and reset all learned Transmission
values to the controllers default values which may temporarily result in erratic shift schedules.

6. With the scan tool, perform the Shift Lever Position Test. If the test does not pass, refer to the diagnostic pro-

cedure for P0706-TRANSMISSION RANGE SENSOR RATIONALITY.

7. For Gear Ratio Error DTCs, use the scan tool to read and record the Clutch Volume Index (CVI) information.

8. Use the wiring diagram as a guide, inspect the wiring and connectors related to this circuit and repair as nec-

essary.

9. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving

under specific conditions, and after controller diagnostic monitors have run.

10. Refer to applicable Technical Service Bulletins (TSBs) for controller software update information. Some condi-

tions can be corrected by upgrading the Engine (PCM) or Transmission (TCM) controller software.

11. Check for any Service Information Tune-ups or Service Bulletins for any possible causes that may apply.

1.

Did any of the above procedures repair the vehicle?

Yes

>> Testing is complete.

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

No

>> Refer to the transmission category and perform the appropriate diagnostic procedure(s).

(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - DIAGNOSIS AND TESTING)

42RLE TRANSMISSION VERIFICATION TEST - VER 1

Perform the following after completion of a diagnostic repair:

NOTE: After completion of the Transmission Verification Test, the Powertrain Verification Test must be per-
formed. Refer to the Engine Category.

1. Reconnect any disconnected components.

2. With the scan tool, erase all Transmission and Engine DTCs.

3. Erase DTC P0700 under engine to turn off the MIL off after completion of transmission repairs.

4. Perform *PRNDL FAULT CLEARING PROCEDURE after completion of repairs for P0706-TRANSMISSION

RANGE SENSOR RATIONALITY.

5. If the Powertrain Control Module or the Transmission has been repaired or replaced, it is necessary to perform

the scan tool Quick Learn Procedure.

6. If the Torque converter has been replaced, with the scan tool perform TCC BREAK-IN.

7. If the Powertrain Control Module or Front Control Module has been replaced you must reset the Pinion Factor in

the Front Control Module.

8. With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temper-

ature is HOT, above 43° C or 110° F.

9. Check the transmission fluid and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure.

10. Road test the vehicle. With the scan tool, monitor the engine RPM. Make 15 to 20 1-2, 2-3, 3-4 upshifts. Per-

form these shifts from a standing start to 45 mph with a constant throttle opening of 20 to 25 degrees.

11. With speeds below 25 MPH, make 5 to 8 wide open throttle kickdowns to 1st gear. Allow at least 5 seconds

each in 2nd and 3rd gear between each kickdown.

12. For a specific DTC, drive the vehicle to the Symptom’s When Monitored/When Set conditions to verify the DTC

is repaired.

13. If equipped with AutoStick

T

, upshift and downshift several times using the AutoStick

T

feature during the road

test.

NOTE: Use the OBDII task manager to run a Good Trip in each gear, this will confirm the repair and to
ensure that the DTC has not re-matured.

14. Check for any Diagnostic Trouble Codes (DTCs) during and after the road test.

1.

Did any Diagnostic Trouble Codes set during the road test?

Yes

>> Repair is not complete. Refer to the Transmission category and perform the appropriate symptom(s).

(Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - DIAGNOSIS AND TESTING)

No

>> Repair is complete.
