Try disconnecting the battery and holding the cables together for a while. This will discharge the capacitors that hold power and memory even when the battery in not connected.


The engine does not start and LED remains off.
1. Check PATS system fuses
2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED)
3. If not go to main dealer

Engine does not start: LED flashes rapidly Leave ignition on until the LED starts to flash a 2 digit code: (sequence- pause-sequence)
Check the following codes:
Code flashes:
1:3 Key code not received. Is key screened by other keys or objects? Try different key: if okay then first key is faulty. If not go to main dealer
1:4 Partial code only received. Try again. If not okay use different key. If not go to main dealer
1:5 Key not programmed into PATS. Program key as above using master
1:6 Faulty link between PATS module and EECV Go to dealer .

You may need to tow to dealer, or you may be able to call a mobile locksmith who has the correct Ford software. You will need to get the code, this will be needed to diagnose any farther. You need a dealer scan tool, or high end snap on or similar.
