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 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:
On right hand drive van’s 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.
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 ( 0251001537)
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.
