Pinpoint Test G: Unprogrammed Encoded Ignition Key (KEYCODE Format OK)
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The PCM disables the engine for 20 seconds every time DTC B1601 is set. The ignition must remain in the RUN position for at least 20 seconds before an attempt is made to start the vehicle with any encoded ignition key. Check the PCM PID ANTISCAN for this unprogrammed key timeout status.
NOTE:
Large metallic objects, electronic debit transponder devices or a second key on the same key ring as the PATS ignition key may cause vehicle starting problems and record DTCs under certain conditions. If a fault cannot be identified, examine the customer's key for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS ignition key while starting the engine. These objects and devices cannot damage the PATS ignition key, but can cause a momentary problem if they are too close to the key during engine start. If a problem occurs, turn ignition OFF and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the encoded ignition key used by the customer is an approved Ford encoded ignition key. (Encoded ignition keys from Rotunda, llco, Curtis, C.E. Marshall, or Strattec are approved Ford encoded ignition keys.)
