Strange Ticking

[wadaman]

So it happened again this AM. As I was driving, I started to hear a strange ticking that sounded just like a turn signal or emergency flasher ticking. But neither set of lights were in use.

I had just turned off my intermittent wipers. Could this be the culprit? This is the second time it's happened in two months. Cured if I turn off the ignition and restart the truck.

Anyone have similar issues / help diagnose?

Mine has done that. It just goes away on its own. It is a stuck relay or something.

I did a search and found this after I had the same thing a few weeks back. there are several threads about this.
also thanks for the belts they are in great condition, so much better than mine were.



If it is coming from the dashboard area it could be the following.....has something to do with the anti-theft device.


Clicking in 10AS Control Unit

AFFECTED VEHICLE RANGE:

DEFENDER (LD) VA992105 to VA999484

VA100300 to VA126471

SITUATION:

INTERMITTENT CLICKING NOISE FROM DASHBOARD

An intermittent clicking noise may be heard coming from the dashboard on some '97 model year Defenders. The clicking noise sounds very similar to a turn signal flasher in frequency and loudness. Once the clicking noise begins, it will continue until the ignition switch is cycled off and then on again. The source of the clicking noise is a relay within the immobilization control unit (10AS unit). A revised unit is now available to address this symptom.

RESOLUTION:

REPLACE IMMOBILIZATION UNIT

To address a customer complaint matching the above description, verify that the source of the clicking noise is the alarm ECU and replace the unit with the latest type.

PARTS INFORMATION:

AMR6430A Immobilization Unit
