Service Bulletin/Repair Instructions
TITLE - Carconfig update on EmiraDS. REASON - A new Carconfig file is available on EmiraDS to support any future ECU (Electronic Control Unit) software upgrades. Because the Carconfig is a common file shared across all ECU software packages, the “New Software Available” notification will be displayed on multiple ECUs, (except for CPC, EIS, EMS, FSCM, and TCM 2L ECUs). Important - This does not necessarily indicate that a specific upgrade is required for each ECU listed, but if a software notification is also available for the DDM (Driver Door Module), upgrading the DDM first will clear the notification for all other ECUs that do not have individually applicable upgrades. ACTION - If a vehicle connected to EmiraDS is displaying the “New Software Available” notification across multiple ECUs, then check to see if software notification is also available for the DDM. Upgrade the DDM first and then check to see if the “New Software Available” notification on other ECU’s has now been deleted.

TITLE Availability of Emira service replacement lower front wishbone ball joint dust covers. REASON An unfinished rough edge, on the steering knuckle assemblies (hub carriers), can, under full suspension/steering movement, contact the lower wishbone ball joint dust cover, resulting in premature wear or damage to the dust cover. Service level dust covers are now available which prevent the replacement of complete front lower wishbones assemblies and associated labour times for suspension/steering alignment procedures because of split or damaged ball joint dust covers. ACTION If damage to the ball joint dust cover as shown above is seen during an underbody inspection (such as routine servicing etc), but the ball joint is still in a serviceable condition, then the rough edge of the steering knuckle casting should be smoothed and the ball joint dust cover replaced.

Odometer mileage adjustment implications of module substitutions on Emira vehicles. For security, necessary data collection and to ensure the correct vehicle mileage is maintained in the event of a DIM/DHU (Driver Information Module/Display Head Unit) replacement, other specific modules as well as the odometer are constantly recording information such as vehicle speed, operating hours and the total vehicle mileage at the same time. Modules Recording Mileage Data Emira DIM (Driver Information Module) SRS (Supplementary Restraint System) module CEM (Central Electronic Module) VDDM (Vehicle Dynamics Domain Module) ECM (Electronic Control Module) Sometimes components including modules are taken either from stock or substituted/swapped over from other vehicles available to aid in diagnosing the cause of a fault with an owner’s vehicle. Any of the modules listed above must NEVER be fitted from a ‘donor’ (correctly functioning vehicle) for this purpose, as once connected to the faulty vehicle, the module with the highest mileage will overwrite the current recorded mileage stored in ALL those modules to that higher mileage. Never be tempted to swap over any of the modules shown on page 1 of the bulletin for either diagnostic fault finding purposes, or in an attempt to get an Emira back on the road.

Availability of ASO exhaust muffler (rear silencer) valve actuator as service replacement part. Until recently the failure of the exhaust muffler valve actuator has required the exhaust muffler and valve to be renewed as a complete assembly. The exhaust muffler valve actuator is now available as a separate replacement part. The advantages of not having to replace the combined assembly are for a faulty actuator are: - Less labour-intensive procedure to replace. - More practical to keep an exhaust muffler valve actuator as a parts stock item. If an exhaust muffler valve actuator is diagnosed as faulty then please determine if the exhaust flow valve mechanism in the rear silencer is operating and moving correctly*, if it is then please fit a new valve actuator instead of a complete muffler assembly. *Actuator replacement is only suitable if the exhaust flow valve mechanism in the rear silencer is operating and moving correctly. If the exhaust flow valve is not operating or seized, then the exhaust silencer or actuator assembly should be replaced.

Installation of the latest DIM (Driver Information Module) software release. Following release of a previous DIM software release (IP18O.02), a false positive telematic notification is triggered in Central and South Americas vehicles which are not fitted with a Telematics Module (TEM). This generates an unnecessary warning symbol and failure message in the DIM for those market vehicles. A new global DIM software upgrade is available on EmiraDS classed as ‘Urgent’ for those market vehicles to resolve this issue. This upgrade is classed as ‘Non-urgent’ for all other market vehicles. Because this is a ‘Non-urgent’ upgrade, it is recommended to only perform this specific software upgrade in the event that the vehicle enters the workshop for any other service, repair or Class 2 action campaign work etc, allowing this upgrade to download at the same time. Any affected vehicle’s campaign status will be displayed on the Lotus Commercial Management System (LCMS). This software upgrade will not affect current vehicle functionality.

Brake pad to rotor stiction damage caused by incorrect vehicle storage maintenance. REASON - Prolonged contact between brake pads and rotors (discs) can result in them sticking to each other (also referred to as brake stiction). This could result in the brake pad material pulling away from its backing plate when the vehicle is eventually moved. Brake stiction occurs when the vehicle remains stationary for extended time periods and can also be exacerbated by: - Long term storage in a moist environment. - The presence of chemical contaminates (such as those found in some cleaning products). - Salt contaminated moisture in coastal regions. Background - Brake stiction is a known issue for sports cars such as the Emira. This is caused by several factors such as the specific chemical composition of the brake pad/rotor material as well as the brake pad, caliper and rotor geometry set up required to achieve the desired braking performance characteristics expected from a sports car. The Lotus Emira was designed and developed as a high-performance sports car and the engineering selection of a mixed metal pad material, the dimensions, and other specifications were tested and approved by the attributes team as well as tested to meet the stringent vehicle homologation targets across the regions, and durability requirements. ACTION - Due to a small number of complaints where brake pad separation has occurred caused by stiction on very low mileage cars, Lotus wishes to confirm to their importers and retail partners the importance of following the vehicle stock maintenance guidelines. Also refer to the ‘Dynamic’ section in long term storage check list attached to the end of this bulletin. As well as to stress that after any cleaning the vehicle it should be driven to dry the brakes, and vehicles should not be exposed to prolonged high humidity or stored in wet areas. To ensure ongoing enjoyment of the product, a specific recommendation was included in the customer handbook under the vehicle maintenance and care section: “NOTE: To prevent binding between the brake pads and discs as well as avoiding any potential corrosion, it is recommended to drive the vehicle for a short distance immediately after washing”.

Generation of P0507 DTC (Diagnostic Trouble Code) when selecting ‘Sport’ or ‘Track’ mode. For Emira 4-cylinder 2024/2025 model year vehicles, a fault within the EMS (Engine Management System) software can cause the unnecessary generation of DTC P0507 if ‘Sport’ or ‘Track’ mode are selected in the sequence as shown below. With the vehicle stationary and engine running, the specific steps to recreate the fault are: - The engine speed has previously exceeded 4200 rpm in the same drive cycle that you wish to select ‘Sport’ or ‘Track’. - Depressing the brake pedal when either ‘Sport’ or ‘Track’ mode is selected. - Then activating the parking brake with the brake pedal still depressed and then selecting D - Drive. - Then releasing the brake pedal with the parking brake still activated. - This will cause the engine speed will rise to 1100 rpm and approximately after 4 seconds, will result in DTC P0507 being generated. Note: This fault within the EMS software affects all market vehicles but will not be noticed except for Chinese and Federal markets, because for those markets, it will result in the MIL (Malfunction Indicator Lamp) being permanently illuminated until the fault code is cleared using EmiraDS. ACTION For Chinese and Federal Market Vehicles If you are presented with a 4-cylinder Emira where the MIL has been illuminated because of DTC P0507 generation: - Please confirm with the vehicle owner if the MIL became illuminated after selecting ‘Sport or ‘Track’ mode? If the owner is unsure, and you have checked and eliminated all other faults associated with DTC P0507 (engine idle speed higher than expected), such as an air intake leak or throttle sticking etc, then: - Clear the code and ask the owner to monitor the situation. Explain to the owner that if they wish to select ‘Sport’ or ‘Track’ mode, then ensure: - That they do not allow the car to remain stationary in D - Drive with only the parking brake activated (i.e. brake pedal should be depressed or either N - Neutral or P - Park selected). - Then, with the brake pedal still depressed and the parking brake still active, select D- Drive. - Then with the brake pedal still depressed, manually release/deactivate the parking brake Or; - Release the brake pedal and the parking brake will automatically release/deactivate. - Allow the vehicle to move forwards or depress the throttle to achieve the desired acceleration.
