# Service bulletin tsb18\-2185

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: 10144182
- Published by NHTSA: 2018\-09\-10
- Manufacturer's number: tsb18\-2185
- Manufacturer's date: 2018\-07\-03
- NHTSA component: ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER; ENGINE AND ENGINE COOLING

## NHTSA's summary

This article supersedes TSB 18\-2024 to update the model years. Some 2011\-2018 Fiesta vehicles may exhibit a lack of heat resulting from a frozen blower motor. This may be caused by snow entering through the cowl panel grille and screen assemblies. Snow may melt in the heating, ventilation and air conditioning \(HVAC\) case allowing water to enter the blower motor and freeze during a below freezing overnight soak. Blower motor fuse F4 in the battery junction box \(BJB\) may also be open and the cabin air filter may be saturated. Follow the Service Procedure steps to correct the condition.

Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module \(BCM\). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab \> Accessories \> Installation \> Wireless RF Keypad Diagnosis Guide \> PPT C \> Step C2.\<br /\>\<br /\> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad.

- [TSB 25\-2570](/bulletins/11025837.md), 2025-12-01, Service bulletin: ELECTRICAL SYSTEM. This article supersedes TSB 24\-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to: Display operation concerns Navigation inoperative Voice recognition concerns Phone connection issues Dropped phone connections Applink related performance Travel Link not present or showing incorrect traffic Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement.

The SYNC 3 universal thumb drive will be able to update the APIM software without the use of a scan tool and does not require the process to be monitored. Ford will be monitoring APIM replacements to confirm TSB directed software updates have been performed.

- [SSM 52335](/bulletins/10251952.md), 2024-03-20, Service bulletin: ENGINE AND ENGINE COOLING. For 2015\-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual \(WSM\), Section 303\-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.

Certain 2011\-2013 Model Year Fiesta Vehicles Operated in the USA Corrosion States Battery Junction Box Clean and Seal In some of the affected vehicles, the position of the Battery Junction Box \(BJB\) in the engine compartment is subject to unanticipated direct road water splash while driving. When vehicles are operated in high contamination/corrosion environments associated with road salt use, moisture and debris can enter through the BJB cover and base, potentially leading to corrosion of the relay and fuse terminals, especially at the front of the box. Corrosion in the battery junction box may result in a variety of symptoms, including a loss of certain vehicle functions, such as the loss of low beam headlamps, loss of high beam headlamps, or vehicle no start.
