# Service bulletin LI80.20\-P\-078308 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 11029090 - Published by NHTSA: 2026\-02\-28 - Manufacturer's number: LI80.20\-P\-078308 - Manufacturer's date: 2026\-02\-27 - NHTSA component: STRUCTURE:BODY ## NHTSA's summary Complaint Please perform the corresponding remedy measures \(points 1\-4\) depending on the determined problem \(points 1\-4\): 1. KeylessGo sensor surfaces do not respond. Door handles can extend/retract if unlocked/locked using the key. No particular fault code. 2. Flush\-fitting door handle does not extend and/or retract. One or more of the following fault codes are current and stored: B185D96; B185E96; B186196; B186296 The following values are present in the control unit log \(A17/x\): Motor\_bridge\_connection\_fatal\_error = True OR Motor\_bridge\_wrong\_direction\_fatal\_error = True \(see attachment for example\) 3. Flush\-fitting door handle does not extend and/or retract. One or more of the following fault codes are current and stored: B185D96; B185E96; B186196; B186296 The following values are present in the control unit log \(A17/x\): Motor\_init\_error\_for\_sensors = True \(for example, see attachment\) 4. Flush\-fitting door handle does not extend and/or retract. The fault code B185911 is stored in the DCU \(N69/X\). Cause 1. Software bug. 2. Software robustness. 3. Software robustness. 4. The resistance of the motor is outside of tolerance. Remedy Please perform the corresponding remedy measures \(points 1\-4\) depending on the determined problem \(points 1\-4\): 1. Perform a reset of the corresponding 'KEYLESS GO' door handle control unit \(A17/x\) via XENTRY \(for example see attachment\) add\-on is available \(add\-on 32204 for XENTRY version 06/25\) Please use one of the following damage codes: 8213H73; 8219773; 8213K73; 8219873 2. A control unit event log for the component part concerned \(A17/x\) must be created and the following values checked in the "Component Errors" section: Motor\_bridge\_connection\_fatal\_error = True \(for example, see attachment\) OR Motor\_bridge\_wrong\_direction\_fatal\_error = True \(for example, see attachment\) If one of the values is "True": Perform an SCN coding on the corresponding 'KEYLESS GO' door handle control unit \(A17/x\) via XENTRY add\-on is available \(add\-on 32280 for XENTRY version 06/25\) The faults must be deleted after SCN coding. Please use one of the following damage codes: 8213H73; 8219773; 8213K73; 8219873 3. A control unit event log for the component part concerned \(A17/x\) must be created and the following value checked in the "Component Errors" section: Motor\_init\_error\_for\_sensors = True \(for example, see attachment\) If the value is "True": Bearing bracket must be replaced. Please use one of the following damage codes: 80A0D73; 80N0D73; 80N0E73; 80A0E73 4. The motor resistance is too low. Bearing bracket must be replaced. Please use one of the following damage codes: 80A0D73; 80N0D73; 80N0E73; 80A0E73 Please note that other published GI documents may also be valid for assessing the problem. For example: "LI72.10\-P\-074316 Flush\-Mounted Door Handle Jams When It Is Pulled Out". If after the remedy points above are performed, the problem is still present, please submit a TIPS case to the PTS\-Body/ Chassis/Entertainment inbox. → In this case, store the damaged parts for further analyses. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2026/MC-11029090-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2026/MC-11029090-9999.pdf) The document is the manufacturer's.
