Iveco Daily Immobiliser Problems & Solutions

Iveco Daily often have the immobiliser system go down with little or no warning resulting in no start or intermittent start & a code  / key icon warning lamp flashing in the dash.. .Vantuner can  delete  / bypass the factory immobiliser completely by simply reprogramming the engine ECU at a fraction of the cost of any alternative.. Models covered all & any 2.8/2.3/3.0 from about 2002 up to about 2011 & beyond. When the immobiliser is working OK, the code lamp, with its key icon, will light for 3 seconds then go off. You will hear the fuel primer  / lift pump wiring for 4 -10 seconds each time you turn the ignition on. Checking there is voltage to the primer/lift pump is a good idea to help establish the actual fault, particularly if you have more than just the immo light flashing. Its located on the passenger side chassis leg.( RHD van’s)  There is a fuse & a relay that feeds this pump:

The LIft Pump

On euro 3 , up to 2006 ish, rectangle headlamps versions, right hand drive ,  the fuse relay board is in the passenger side dash , behind a pull off panel. The pump relay #25837 is at the bottom of the fuse board. From the fuses go towards  the steering wheel & its the 3rd relay along the bottom.
With an active & working (or fully disabled immobiliser), assuming ECU & wiring are okay, the pump will run until for a few seconds each time ignition is turned on, until enough pressure is created. Power the pump with 12v, check power to fuse & correct relay function, also , if its getting 12v but not working , if you give it a couple of taps it may work. There is a bleed valve on the filter head in the engine bay you can open to clear trapped air.

 

The pump’s fuse is number 47 & has  rating of 10A. Along the bottom of the fuse board, the bottom row it is the 4th fuse along in the direction of steering wheel.

1st Fuse 34 20A. nearest passenger door.
2nd Fuse 11 15A.
3rd Fuse 24 10A.
4th Fuse 47 10A.
5th Fuse 18 10A

To work on the immobiliser the engine ECU must be removed & posted in, once you get it back , disconnect the immobiliser box (pre ’07’s)  , reinstall the engine ECU & you’re good to go. The immobiliser’s / key  code lmap in the dash should now be off ( if Euro 2 or 3 type ) & the van will start. Usual turnaround is 1 to 2 days or you can book in for it to be done while you wait if you bring it here by car etc. Euro 4 2007 onwards will still have the immo lamp lit.

There is a small filter positioned just after the lift pump, rarely blocked but worth ruling  out.

A common failure on no start iveco daily is an  earth problem & also power to ECU problem. Check or redo engine to chassis earth & check you have 12v feed to the engine ECU. With the protective cap removed from the larger of the 2 ECU connector plugs you will see larger pins on one side of the ECU , pin 1 is +12v & pin 3 is Ground. There are others but start with those.  The 12v feed  issue is usually a faulty relay, see guides linked to below.. Often with an ECU power problem, the dash looks like a christmas tree as in many lamps lit not just immo lamp.

More detailed  fuse & relay Info

This fuse & relay guide page is for Euro 4 ( 2006-2011) Iveco Daily, look for “EDC16” items as well as fuel pump, “EDC16” being the Bosch model designation for the engine ECU used on Euro 4 Dailies..

This fuse & relay guide is for Iveco Daily 2000-2006.

The ECU on RHD vehicles , is located under bonnet, on the right hand side , further right than the battery so remove the battery to get access,  & remove any bracketry prior to posting. Its easy to short connections on these van’s so one tip is to remove the positive terminal cable from the battery & put it straight into to a glove or 2 then stuff it out of the way.

The postal remaps page here has details of where to send & how to pay etc, & although you can drop it in by appointment if you prefer, don’t be shy about posting it, the units are shockproof & I’ve never lost one in 8 years of doing this via Royal Mail Special Delivery  – You can just use a size H Jiffy bag on all but the earliest type in the 1st picture  & a small section of cardboard to protect the connector end.

You’ll find your engine ECU is made by Bosch & has one of the following part numbers  :

0281001537, 0281011228, 0281012193 – all of these can have the immobiliser deleted /bypassed.

Here is the earliest type ( 0281001537)

Iveco Daily EUro 2 Engine ECU Bosch 0281001537

Here is the one that most commonly fitted to vans that get problems – part number 0281011228, the Euro 4 van’s with ECU part number 0281012193, have an almost identical look.

Below is the immobiliser box you have to permanently disconnect if your van is a Euro 2 or 3 , (produced from roughly 2001-2006)., The box, if fitted, is located just forward of the steering column , under the dash, Its tricky to see & even harder to remove but you can unplug its two plugs  in situ or undo the 2 Torx bolts holding it in & you ‘ll then find unplugging much easier.You can locate the immo box by tracing the wiring down from the receiver ring that surrounds the ignition barrel.

This is a picture of the ignition & key, receiver ring that picks up a signal from the key, & wiring to the immobiliser box, to give an idea of the offending systems components size & look.

Whilst the ECU is here , speed limiter removal or tuning for economy  / power , torque can also be carried out.

 

Emails /Feedback

Just an update on my van having now driven some of my usual routes.  Feel free to publish this on your website if you’d like.
My 2005 Iveco Daily 35s12 does a lot of fully laden towing with a box trailer, weighing in at over 6000kg.
As a standard 2.3l engine with 116bhp it would struggle on hills, and cruising at 56mph would normally need 4th as i could not maintain speed on any hint of an incline or headwind in top.
After your postal remap the van is transformed, it comfortably holds 5th with power in reserve, Falmer Hill on the A27 nr Brighton can be topped in 4th at over 50mph (previously with a run up and changing down to 3rd we would struggle to maintain 40mph) and Handcross Hill on the A23 maintaining 56mph in 4th. And yes, this is whilst towing the fully laden box trailer.
And its silly quick when driven solo!  I can’t remember how much extra torque you dialed in but feel free to add it.
Thanks very much Martyn, a happy customer 🙂 ( Olly, Chief of UK’s only Iveco Forum)
