This will result in immediate failure of the calibration operation and a message advising that error code 18 or error code 40 has been generated. This issue is discovered only when a transmission or clutch calibration is attempted after repairs such as clutch replacement, the Transmission Electronic Control Unit (TECU) software is updated, or after an Over The Air (OTA) programming event. Solution If transmission or clutch calibration fails immediately after the operation is started following a clutch replacement or programming operation with the Errors above: 1. Disconnect the TECU from the chassis wiring harness. 2. Connect directly to the transmission with PTT using the appropriate adapter. 3. Perform operation 4000-07-04-01 Transmission Calibration (Transmission Removed), located under the Calibrate tab. 4. After successful calibration, reconnect the chassis harness to the TECU. 5. Run Operation 4320-07-03-01 Transmission, Clutch Engagement Point Calibration. Select Option B. If the calibration is successful: The existing invalid X1 value has been overwritten and the remainder of the repairs (if any) can be completed. If the calibration fails again with the same error code for R1AAE routine: An eService case is required for additional assistance. • The eService case MUST include: - This Solution Number - A description of the original customer complaint. - A thorough description of all work performed up to the point of the case's creation. - A DTC Readout if codes are present, active OR inactive. - Any screenshots or photos that are relevant to this situation. Internal comments (BO) If an eService case is submitted for this issue: 1. Check that parameter P1AOB Clutch X1 Default Value is loaded to the vehicle in VDA or Configurator. If P1AOB is missing, set to 0 or set to an invalid value it must be added and/or updated with the correct value below: • AMT-D: 25.0 mm • AMT-F: 20.0 mm If P1AOB is present and set correctly: The gear selector should be checked to verify that it is reporting Neutral to the TECU.
