Pinpoint Test H: Invalid Key Code Format From Encoded Ignition Key Transponder
NOTE:
Large metallic objects, electronic debit transponder devices or a second key on the same key ring as the passive anti-theft system (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.)
