U1410-IMPLAUSIBLE FCM VARIANT DATA

For a complete wiring diagram Refer to Section 8W.

Theory of Operation

The Transmission Control Module receives vehicle information over the CAN Bus from the FCM/TIPM and stores this information in the EEPROM of the controller. This information is compared information received over the CAN Bus. If the information does not match, the DTC will set.

• When Monitored:

  Ignition on with system voltage between 9.0 and 16.0 volts.

  FCM/TIPM variant data received more than twice in a row over the CAN Bus.

• Set Condition:

  One or more FCM/TIPM variant data received over the CAN Bus is not in a valid range for the period of 5.0 seconds.

Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD PROCEDURE)

• This DTC is an indication of either the FCM/TIPM was replaced with the wrong configuration (improper tire size), or the TCM was replaced with the wrong configuration. If either controller was replaced, confirm the part numbers to the Vehicle Identification Number (VIN) and program or replace as necessary. With the scan tool perform a TCM relearn procedure.
• Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD PROCEDURE)
