Technical Imobiliser Faulty 2003 2.2 JTD

[Pat H]

Tried to start the car after a short stop last night and it wouldn't start and displayed "Immobiliser Faulty"
Tried the second spare key but no joy.
Used another car and tried the Ulysse a hour or so later and it worked fine.
And has been fine since.

Was this just a one off?

Or a symptom of something more serious?
Any clues as to how to resolve it a short notice if it happened somewhere inconvenient?

Thanks

I had the same thing last week. I had disconnected my battery to reset ECU for central locking. When I connected the battery, the central locking worked fine, but the first 5 attempts to start, the car gave the same message. Waited for 5 minutes and message disappeared and didn't come back... Don't know what could have caused it on your car.

battery/charging ok? dont forget to check for water in engine bay fusebox.

If it keeps happening have the fuse box under the bonnet out and check for water ingress. Quick reset is to disconnect the battery for a bit then try again If display shows engine imob fault re-marry key to ignition (press hold lock button on key while you turn on to off three times ) And try again.

Well been fine since. So maybe just a fluke. But thanks for the advice.
