Whats wrong with the Smart Lock? - Ford Forums

lx^el · 09-22-2004, 17:29

Went to start up my car today and no go! :( (EF Falcon 4ltr)

When you turn the key to the "on" position, the "Smart Lock" light flashes 5 times in a row, then stops, and repeats for few times, after which it just goes balistic.

The starter motor works, but the smart lock doesn't allow for fuel or spark or something.

What do i do?

I rung up Fraud....err Ford and great help they were by saying "well it's a smart lock problem, you'll have to bring it in" :| funny that, considering I can't even start it!! and the bloke could not tell me what the 5 flashes indicate.

I've had the problem once before, but just checked all the wires leading to the smart lock unit, and it started after that, but it doesn't seem to be doing that today.

According to my workshop manual, 5 flashes indicates either:
1.Electronic lock assembly clock circuit open, or
2. Electronic lock assembly ground circuit open.

To check for either, measure continuity between the pins of the Smart Lock module and Electronic lock as below:
Lock <-> Module
1 <-----> 26
2 <-----> 17
3 <-----> 13
4 <-----> 15
If any are open circuit, repair loom and recheck system.

If no open circuit is found, check for bent or corroded pins on both module and lock (replace any damaged unit).

If no fault there, then connect a new Smart Lock module, download security codes and verify system.

If you still have the fault code (5 flashes), then replace the electronic lock assembly.

EL Fairmont starting problem - HELP!

I believe the technical name for it is "DUMB LOCK"
It's a ford problem, from the door actuators (having spasms)to the Module itself (bad solder joins)etc.
