Ignition key is ON.

The Bus OFF failure is not present, the TCM receives messages on the CAN network, the CAN communication between the TCM and PCM is not lost, there are no dual port RAM faults and the CAN message was read at least once.

A signal toggle bit and a signal parity bit are sent by the PCM within the CAN message. In order to be sure the message content is continuously updated, the value of the toggle bit changes from 0 to 1 and vice versa every two messages. In order to be sure that the message content is valid, the parity bit value is set so the sum of specific signal bits of the message content, plus the toggle bit, plus the parity bit is an even number. If the toggle bit value does not change for a calibrated amount of time or the signal parity is not verified for a calibrated amount of time then DTC U0401 is set.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to 6F24 PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE .

Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN BUS Off Performance DTC present.

When the TCM detects an incorrect CAN ID from the Anti-Lock Brake Module (ABS).

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to 6F24 PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE .

NO TITLE

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 in accordance with the Service Information.
2. Testing should only be performed with the battery fully charged to avoid false diagnosis.
3. With the scan tool, read Powertrain (PCM) DTCs. If Engine DTCs are present, and perform to the appropriate diagnostic procedure(s) before proceeding. Refer to the «DTC INDEX»(ref-646339) article .
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. Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, driving under specific conditions, or after controller diagnostic monitors have run.
6. Perform any applicable Service Bulletins for controller software update information. Some conditions can be corrected by upgrading the Powertrain (PCM) or Transmission (TCM) controller software.
7. Check for any Service Information Updates or Service Bulletins for any possible causes that may apply.

Were there any repairs made that fixed the vehicle?

Yes

1. Testing complete.
2. Perform the TRANSMISSION VERIFICATION TEST. Refer to «6F24 TRANSMISSION VERIFICATION TEST»(ref-646323-S37521357402014072800000) .

No

1. Perform the appropriate diagnostic procedure.

PROGRAMMING THE TRANSMISSION CONTROL MODULE (TCM)

Note. While performing the TCM programming procedure, the vehicle battery must be maintained between 10 and 16 volts. Ambient temperature must be between 0° C (32° F) 60° C (140° F). Vehicle must be in Park with brake pedal depressed.

1. Using the scan tool and Dealer Connect, download the appropriate TCM flash file to the scan tool.
2. Ignition on, engine not running.
3. Vehicle in park with the brake pedal depressed.
4. Following the menu on the scan tool, program the TCM.
5. Clear any stored DTCs.
6. Road test the vehicle above 40 m.p.h. for at least two minutes.
7. With the scan tool, select View DTCs in the TCM. Are there any DTCs present? Yes Perform the appropriate diagnostic procedure(s). No Test Complete Perform the TRANSMISSION VERIFICATION TEST. Refer to «6F24 TRANSMISSION VERIFICATION TEST»(ref-646323-S37521357402014072800000) .

1. Perform the following after completion of a diagnostic repair: Reconnect any disconnected components. Connect the scan tool to the Data Link Connector (DLC). With the scan tool, erase all Transmission and Engine DTCs. If the transmission or valve body has been replaced, a Clear Learned Values procedure must be performed with the scan tool. With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temperature is HOT. Check the Transmission fluid level and adjust if necessary. Refer to the «STANDARD PROCEDURES»(ref-646221-S28379567152014072800000) information for the Fluid Fill procedure. Road test the vehicle allowing the vehicle to shift through all gears. Check for DTCs during and after the road test. Were there any Diagnostic Trouble Codes (DTCs) set during the road test? Yes Refer to the «DTC INDEX»(ref-646339) article and perform the appropriate diagnostic procedure. No Repair is complete.
