IWE System
WARNING: This page is about a different car, the 2023 Ford F-150 Lightning and 2023 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The IWE system consists of the following:
| 1 | IWE s (spring-loaded Electric hubs) |
|---|---|
The IWE system uses electronically actuated hubs to engage or disengage the front wheel hubs from the front half shafts.
When the 4WD system is in 2WD (2H) mode, the TCCM energizes the IWE s thus disengaging the front hubs from the front half shafts.
When operating in any 4WD mode, the TCCM deenergizes the IWE. An internal spring keeps the IWE clutch ring engaging the front hub and the front half shaft.
The TCCM has one startup strategy that affects IWE operation after initial key cycle:
- When ambient temperature is below 32 F (0 C), IWE s engage after initial key cycle and a driven gear is selected. The hubs stay engaged regardless of a 4x4 mode change for approximately 2 miles (3km). Once the set distance has been achieved, IWE s disengage (if the vehicle is in 2WD (2H)). Distance traveled resets only if the temperature is below calibrated threshold and another key cycle occurs or if customer shifts to Park (P) and back to a driven gear within the same key cycle. The TCCM uses this strategy to warm up the front axle in cold temperatures to improve driveline synchronization.
