The service shifter message comes on in the cluster and the lever gets stuck in park "P" and it can be present the follwoing DTC: - U11E3 - TCM Lost communication with ESM on D-PT CAN - U0103 - Lost communication with Electric Gear Shift Module - U0101- Lost communication with DTCM - U0418 - Implausible Data Received From Brake System Control Module - U0402 - Implausible data received from TCM **NOTE: Prior any shifter replacement Refer to TSB-21-016-25 2024-2025 WS - Valve Body Replacement. Recommended Diagnosis procedure: 1. Confirm if U0101 -Lost Communication with TCM or U0418 -Implausible Data Received From Brake System Control Module are present, if so check the Valve Body CAN Terminals any corrosion. 2. Check the wiring connectors between the ESM and the TCM and check voltage. 3. Check the pin header for the ESM for any bent pins. 4. If wiring and voltage are good and the DTCs (U11E3 - TCM Lost communication with ESM on D-PT CAN & U0103 - Lost communication with Electric Gear Shift Module) are still present, erase them with the scan tool. Reset ECU. 5. if DTCs for loss communication are still active at the ESM and you are still unable to shift then replace the Shifter module.

91006412025-08-13. Service bulletin. POWER TRAIN. Symptoms/Condition: Shifter reports loss communication AND NO OTHER MODULES report the condition. Diagnostic: Please make sure ONLY shifter reports loss communication. If there are other modules reporting loss communication, then follow the existing service procedure Repair Procedure: 1. Verify Complaint - ESM reports a Loss of Communication (LOC) DTC, but no other modules do. - If multiple modules report the same LOC, the ESM is not the cause (its not a gateway module). 2. Read DTCs - Relevant codes: U0101, U0140, U0155, U0129, U11C3, U0402, U0422, U0423, U0415, U145D. - If multiple LOC DTCs are present: a. Check battery health, system voltage, and TCM (including valve body). b. If TCM goes offline, ESM may falsely report LOC DTCs. 3. Check Environmental Data - Look for voltage/system issues at the same mileage. a. If DTCs clear, do not replace ESM. b. If not, inspect: b.1 Module connectors/pins: If damaged, dont repair shifter. b.2 TCM connectors/pins: Same rule. b.3 AGSM connectors/pins: If damaged, repair shifter. b.4 AGSM wiring harness: If damaged, dont repair shifter. 4. Review Past Service - Confirm battery and TCM-related repairs are still effective. a. If not, fix and clear DTCs. b. If yes, continue. 5. Check for Other LOCs - If other modules report LOC to the same module, inspect that module. - If not, repair the AGSM. Additional Description: - The ESM only communicates with the TCM and is fully controlled by it. - In non-combustion engines, the TCM is replaced by the PCM. - If a stored DTC in the ESM disappears and doest return, do not replace the ESM.
