2003 FORD MUSTANG key

PINPOINT TEST G: THE ANTI - THEFT SYSTEM DOES NOT OPERATE Test Step Result / Action to Take
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 ensure the encoded ignition key used
by the customer is an approved Ford encoded ignition key (encoded ignition keys from Rotunda,
Ilco, Curtis, or Strattec are approved Ford encoded ignition keys). F1 USE THE DTCS FROM THE INSTRUMENT
CLUSTER SELF- TESTS z
