* Check Engine light illuminates when fault is present. On California and all Econoline, CHECK ENGINE light will turn off if no fault is detected for four consecutive drive cycles.

** Transmission Control Indicator Light (TCIL) flashes when fault is present.

*** Refer to the Powertrain/Transmission Group in the Service Manual for diagnostic procedures.


Note: Speed control DTCs will be set during KOER Switch Test if the vehicle is not equipped with speed control. This is a normal condition. On these vehicles ignore the following DTCs P0565-P0566-P0567-P0568-P0569.
