- How the car detects it
- C00A6 is the general code for the transfer case actuator, the motor unit that presses the transfer case clutch or moves its shift mechanism. Ford uses it with many failure-type suffixes. SSM 49669 covers 2020–2021 Explorer and Aviator AWD with C00A6:07, :18, :19, :4B, :66, :71, :74 or :99 and an AWD lamp, noting that the clutch actuator is not always at fault and that revised pinpoint tests should be followed. SSM 52152 links C00A6:71/:74/:99 with C00A7 and C00A8 codes on 2020–2023 Explorer/Aviator to a harness rubbing on a heat shield where it runs to the actuator motor. TSB 25-2373 ties C00A6 together with C0631 on 2020–2021 models built up to 30 August 2021 to the unit that decouples the front axle, which is swapped together with an updated intermediate shaft. Bosch describes this kind of transfer case clutch actuator in detail.
