Service bulletin TSB-131-24009
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.

NHTSA's summary
Trouble shooting flow chart to show the process of self-diagnosing tyre pressure monitoring system faults before contacting Emira Support. The descriptions of Diagnostic Trouble Codes (DTC’s), generated if a fault is detected in the TPMS, may identify the general monitoring system or circuit where a fault has been detected, but may not be able determine the specific module, component, or circuit location at fault. Therefore, DTC information can be misinterpreted by the technician resulting in excessive time, or unnecessary replacement of TPMS module components to rectify the TPMS fault.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
| 131-26004 | 2026-02-09. Service bulletin. Under certain conditions the warning message shown to the right can be activated in the driver display when both the brake lamps and a turn signal are activated at the same time. The cause of this issue has been identified as the unique Federal rear lamp combined position/brake/turn indicator configuration. Even with this message displayed, the tail lamp and turn signal should work as intended. Fit the tail lamp link harness between the connectors. Repeat the procedure on the right-hand side rear tail lamp. Put the vehicle into active or driving mode and activate the brake lamps and turn signals at the same time to ensure that the warning massage does not appear in the driver display before refitting the wheel arch liners and rear wheels. |

| 131-25011 | 2025-08-05. Service bulletin. Updating the CEM (Central Electronic Module), to the latest level software. A new CEM SW update is being installed as a production running change. This new SW update will implement the Car Configuration Logic changes to reduce the DTCs reported when cars with a non-convenience seat pack are requested, (memory seats and auto angling mirrors not fitted). - Check and identify any affected Emira vehicles from your inventory stock, dealer demonstrators and customer vehicles to ensure that this campaign action is performed at the first opportunity. Any affected vehicle’s campaign status will be displayed on the Lotus Commercial Management System (LCMS). NOTE: This CEM SW update will not affect current vehicle functionality Preparation: Using the Lotus Insight tool*, the Emira Diagnostic System will show the availability of a new software version for the CEM. *Note: This MUST be done using the Lotus Insight Tool. |
| TSB-131-24020 | 2024-09-04. Service bulletin. New operation required for Emira service schedule sheets. During normal road use, it has been identified that dirt/grease/road debris can accumulate around the WSS (Wheel Speed Sensors) and the magnetic rings located on the rear of the hub units. This accumulation may affect the signal being transmitted to the VDDM (Vehicle Dynamics Domain Master), also known as the ABS module, which can result in the generation of diagnostic trouble codes, activating the illumination of the amber colour MIL (Malfunction Indicator Lamp). ACTION To ensure continuing customer satisfaction, Lotus will update the ‘Braking’ section of the V6 and 4-Cylinder Emira service schedule sheets to include a new operation to remove any loose debris on all four WSS using a suitable airline, then inspect and clean the WSS with a clean cloth and brake cleaner to remove any dirt deposits. At the same time the corresponding magnetic rings on the rear of the hub units should also be cleaned. This new procedure should be carried out at every service interval.

| TSB-131-24017 | 2024-08-06. Service bulletin. Potential cause of dTPMS (direct Tire Pressure Monitoring System) sensor failure. Lotus has been made aware of that some Emira vehicles have been affected by inaccurate dTPMS tire pressure readings being displayed, or, in some instances, tire pressure readings not being displayed at all. One cause of this issue has been identified as the excessive water-based lubricant being applied to fit the tire valve to the wheel rim at the wheel assembly procedure. The moisture/humidity entering the tire pressure monitoring sensor, causes corrosion and damage to the internal circuits, resulting in communication failures between the sensors and the vehicle. As a production running change, from VIN SCCLEKAX3RHB13186, a smaller quantity of gel-based lubricant is now used to fit the tire valve to the wheel rim. ACTION If diagnosing a dTPMS fault on an Emira (prior to 2024 model year VIN shown above)*, because of inaccurate dTPMS tire pressure readings, or no readings displayed at all, then: - Use the diagnostic flow chart shown on Technical Service Bulletin TSB-131-24009. - If the diagnostic route taken states that the next course of action is to replace a TPMS sensor(s), then request prior authorisation to fit a vehicle set (4) dTPMS sensors. |
| TSB-131-24012 | 2024-05-07. Service bulletin. Technical Service Bulletin issued to ensure the correct use of the EmiraDS and the Lotus insight too to prevent vehicle or diagnostic issues. Bulletin contains information that has been prepared in an attempt to resolve recent issues reported to Technical Support and to prepare the global dealers for the release of the additional functions within EmiraDS to support the Emira 2L version. Information contained in the TSB must be followed to ensure optimum performance of the EmiraDS with the Lotus Insight tool. |
| TSB-131-24003 | 2024-03-20. Service bulletin. Installation of the latest ECM software for Emira vehicles in the Federal market to ensure that they meet the current CARB compliance requirements. Check and identify any affected Emira vehicles from inventory stock, dealer demonstrators to ensure that this campaign action is performed at the first opportunity. Install the new software part number V6 J1U4 as stated on Service Bulletin 131-24003 |
