PATS Immobiliser Fault Codes

Introduction

If a fault develops on a vehicle fitted with Ford PATS there are a series of simple checks which can be carried out before proceeding, if necessary, to the FDS2000 diagnostic programme. There are also a number of self-diagnostic two-digit codes which may be displayed by the indicator LED which indicate a specific fault and could avoid the need to proceed with the FDS2000 diagnostic programme.


Note: The indicator LED must be carefully observed and the sequence of flashes noted.


When the two-digit codes are flashed, for example 1:3, a single flash followed by a break, followed by three flashes and a break, will be repeated ten times before the LED finally goes out.


Fault Finding Procedure

Fault - Engine does not start or crank: LED does not illuminate


PATS system fuses in central electric box. Fit or renew as necessary.

If alarm is fitted check whether LED functions for alarm: If OK go to FDS2000. If not OK check cigar lighter fuse (this also supplies power to LED).

Fault - Engine does not start or crank: LED flashes rapidly. (Engine is immobilised but key will not cancel immobilisation)


Check: Leave ignition switched on for at least one minute or until LED starts to flash two-digit code. Note the code being flashed and compare with the following list:-


Code Problem Check

1 : 3 Key code not received is the key obscured, try again with different key, key may be damaged/faulty 1 : 4 Partial code only received is the key obscured, try again with different key, key may be damaged or faulty 1 : 5 Key not programmed to PATS Programme key 1 : 6 Faulty link between PATS and EEC v module check with FDS2000

Programme key


Fault: Engine does not start or crank: LED illuminates for 4 seconds and goes out: (PATS is working correctly, possible fault elsewhere in system)


Check:

Starter solenoid relay, renew if necessary.

If still no start, Go to FDS2000.


Fault: Engine cranks but does not start. LED illuminates for 4 seconds and goes out (PATS is working correctly, fault elsewhere in system)


Check:

Power supply to PCM or fuel pump (diesel), if still no start, Go to FDS2000 Check PCM fault, Go to FDS2000 (Petrol and Gas engines)

Fault: Engine starts but LED stays on.


Check:

Leave ignition on (engine running) for at least one minute or until LED starts to flash two-digit code

2 : 1 Less than three keys programmed into module: vehicle can be driven but one or two more keys should be programmed into memory.
