Just out of interest have you tried to re sync the remotes like when you change the batteries in them?
Oh there is no eka for the transponder key Freelander.
Tried it just now and it still won't work. Will be booked into the dealers today for later this week. I have keys and a fob. Does mine have eka?
 
Hippo, there is a place near me where you can send ecu from under bonnet and ccu under dash. they did mine for 15 quid a few yrs ago. Bri

Thanks. I picked it up today. 1 hour labour at the reduced rate for older vehicles of £90 per hour + vat. They re-synchronised the immobiliser to the engine computer and it happily started. :)

I now have more time to write a fuller reply.

Cutting a long story short my Freelander needed to have his immobiliser synchronised to his engine computer as the rolling code was feked up when I tried to add another fob to my Freelander. Ma hippo started ok before trying to add fobs and stopped starting thereafter. I can only summarise something went wrong during the process. He's a 2001 v6 and I was using a Hawkeye with version 5 software. The engine would turn over but not start. My Hawkeye confirmed my hippo's immobiliser status was "mismatch" which means the code isn't synchronised to the engine computer. The engine computer had error code P1672 which confirms this. I tried using my Hawkeye to synchronise the immobiliser to the engine computer as it has a synchronise ecu option in the security \ ews3d menu but it didn't solve the problem. I have no idea if the synchronise ecu option actually did anything, tried to synchronise but failed or may be an option in the menu which doesn't do anything. I guess the way forward on this is for hawkeye users not to use the synchronise ecu option as it may fek up your immobilisers rolling code, unless we find a definitive answer to what it actually does and if it works. I tried it on my hippo as it was already feked up and therefore needed help from a more comprehensive computer like Land Rover's T4 test book. It's possible other systems may be able to perform the synchronise process but I sent my hippo to the main dealer as they have T4 and know what they're doing.

I had some initial problems with the main dealer who didn't book it in even though they knew I had organised transport to carry him there. Their service system didn't have the correct information to connect me and my hippo together. The bloke struggled to understand what the problem was, why it happened, why I hadn't broken down when my hippo was on the back of a breakdown truck and the fact that I knew what was wrong and had access to his error codes. After going round in circles for some time he then booked it in and I walked home.

The following day he phoned to advise my hippo had been fixed. After some prodding he said they did a diagnostic which advised the rolling code wasn't synchronised so they synchronised the immobiliser to the engine computer and he started first time. I guess they get all sorts turning up thinking they know what's wrong. He was suspicious of my Hawkeye and the fact I had used it to program a 3rd fob. Originally 1 fob failed for some time so I bought another and then the failed one started working again. So I used my Hawkeye to program all 3 fobs to my hippo on the basis one of the fobs may fail in the future. What could go wrong? :doh:

I had to pay the main dealer £90+vat for 1 hour labour (reduced from the usual rate of £110+vat as it's an older vehicle) and £45+vat to hire a breakdown truck to carry ma hippo to the main dealers. I lost 1 day holiday too as I took the day oft to take ma hippo to the main dealers.

During the fob programming process you have to go into the security \ ccu \ transmitter (fob) programming option and press the unlock button on each fob 8 times. If the Freelander receives the signal from the fob 8 times the horn will bleep on the 8th unlock press to acknowledge it's worked. You can then add additional fobs. Previously working fobs need to be added at this stage or they will be disabled and stop working.

The first time I tied to program my fobs my hippo didn't bleep his horn. None of the eggsisting working fobs or the new fob would program. I had a look in the live data section of the security \ ccu menu and none of the values would update real time. This sometimes happens when looking in menu's with ma Hawkeye. If I come out of the menu for that area of ma hippo and then go back in, it will then probably work ok. I would advise others who would like to use their Hawkeye to program fobs to check the security \ ccu \ live data option displays data in real time as you operate items in the list, and see a change of state to prove all is connected and working ok, before using the transmitter option to program fobs. This will ensure your Hawkeye is at least talking to your Freelander's computers correctly and hopefully reduce the risk of problems.

Both Bearmach and Omitec go out off their way to tell me they make and own the hawkeye product. The one thing they don't do is produce a manual for it. I appreciate it costs money to write manuals. I've written technical manuals at work so I know it's time consuming. I'm not after a complete guide to hippo diagnostic and repair. A simple manual on what each menu item does and what is eggspected from it would do. I give no apologies for wanting a manual. It's irresponsible not to provide one and leaves Hawkeye owners facing unknown problems when using their Hawkeye. It adds an unknown element of risk to the product which the owner shouldn't have to face. A warning that trained personal should only use a particular option isn't enough.

As my hippo was propper feked due to the mismatched rolling code I had a play with loads of different options on my Hawkeye, knowing the main dealer would correct any problems as he was going there for repair anyway. I have lots of video's of this. Black box solutions also make diagnostic kit and they put loads of information online for bbs owners and potential buyers to read. Currently the Hawkeye has a "suck it and see" philosophy of ownership. They don't pay me to put video's of my Hawkeye online while I use it on ma hippo. It's about time they got their act together or at least give me a free code to add Freelander 2's to my Hawkeye, for the free product advertising they receive. :boink:

I'm putting the problems I've had down to eggsperience. I still like the Hawkeye but feel let down as a Hawkeye owner due to the lack of information/manual. If another product were available for test or I could see it being used online then I would probably buy it if it had a manual and/or support. I'm still glad I have the Hawkeye. On this occasion I was able to see the status of my hippo after the problem occurred. I could confirm the presence of the key in the ignition and see which key number it was. I also found I could put the key with the LR logo against the ignition key hole and the key would be detected, without inserting it in the ignition. This proves the rave disk is correct in saying the field of recognition is 20mm. When doing the same thing with the other side of the key it wasn't detected. I could also use all 3 fobs to superlock/alarm/spe unlock and unlock my hippo and see his status change on ma Hawkeye. I was able to look at all his different computers (not just the engine computer which cheaper odbii readers only look at) to read and clear faults. The engine computer contained the P1672 code error which I could remove and get back after trying to start ma hippo. So all things considered I'm glad I had a diagnostic device which could help me. If it were not for that then I may have been done over for a new ignition, new keys, new fobs, new immobiliser or one or more of these item's by an unscrupulous trader who could have ripped me oft. That doesn't forgive the lack of manual issue. It's simply a case I was more informed as an individual trying to fix ma hippo with a Hawkeye, as opposed to not having it. The real gem of information was the immobiliser status reading "mismatch" to confirm the error code P1672. Also the immobilised count value increased after failed starts. The main dealer used the phrase "check and report - code P1672 immobiliser needs to be synchronised to engine [computer] customer self diagnosed..."

Ma hippo is now fixed and running ok. :)

Interresting.
I'm usually active at the Norwegian Land Rover forum.
Yesterday 18th of August, I had a customer coming to inspect (and possibly buy) my 4th rebuilt Freelander (2001MY). It's so nice New polished, new engine and.. Ok To the point:
One hour before our appointment, I realized that the FOB's didn't work. Hawkeye tried to reprogram them, but newer found the FOB's. After some investigation, we found the the connection plug to the FOB receiver located above the instrument cluster had mis-entered, and had a non-connection to the black lead. OK, staightened the pin and reconnected. VIOLÀ - FOB's alive again. YEAH! And even before the buyer shows up. Jumps in and starts the car.... 1 sec and dies again. IMMOBILIZER... On and off with alarm: one sec. of engine running. Tries to sync ECU with Hawkeye, and the same as Hippo states happens: Absolutely NOTHING. Right back to the menu. So there I am.
Waiting for someone with a T4 showing up...

The buyer? He came, inspected the nice, clean looking car. We tested everything without the engine. When the wire on the rear passenger door broke and the window was stuck -he said politely that we'll be in touch when the car was running again. I guess that he took the hint and will newer look for a Freelander again. EVER...

I have updated my post above.

Roy, do you get error code P1672 in your engines computer?

It's annoying to see someone else with the need to synchronise their immobiliser to the engine computer only to find the menu option eggsists in the hawkeye, but doesn't look like it's doing anything.

This could be deliberate so as to maintain the vehicle security? which you'll agree is important especially with the ease of acquiring modern hand held devices.
 
Hi,
I don't get an error code at all.
And for the security of the vehicle, I don't worry at all.
What kind of idiot will steel something like this?
I've rebuilt 4 Freelanders now, and 8 engines + a unnumbered amount of repairs for other people's Freelanders.
Somewhere I could read that it was quoted that the gasoline engines was designed by satan and built by monkeys.
At this stage I can't see that I find too much evidence for proving that this is wrong.

I've now read all U've written Hippo, and couldn't agree more!
My problem is that there are no error codes what so ever.
The Hawkeye says that Immibiliser is mobilised. I don't know what that means. Locked or not?

I regret to say that I'm considering to purchase a mobile T4 from China. US$ 2.850.00
I don't trust the hawkeye any longer.
A vendor that don't even know their own product enough to write a user manual...
I should have known better.

Just looked at the Lynx manual.
It's almost a blueprint from what I read in the hawkeye manual.
But there are nothing about synchronise ECU in the Lynx manual.
Also it looka as it's locket to ONE VIN??? Just as the BlackBox...
I've found something in China. a T4 diagnostics. US$ 2840 was the final offer....
But what is this? They claim it to be original.
Original fake or what?

I did wonder but if they didn't want the option to work then they would simply put a message in to say it doesn't work for security reasons or just leave the option out of the menu instead.

My hippo is a 2001 v6. Not sure what your engine is. If I go to: ems \ ems2000 \ live data and drop down the list I get the following:

vehicle state: immobilised
immob. status: ignition off

If I turn the key to from position 0 or 1 to 2 the immob. status changes to mismatch.

Does yours do this? Have you tried disconnecting the battery and reconnecting it?

It's probably fake. I think omitec make T4. There's also a lot of laptops for sale on the web with T4 software but they all say there's no cables. Another con. they buy an old laptop and install the software with no license then sell it with no cables.
 
Hi,
Mine is a 2001 1,8litre
I can't use EMS2000, only MEMS3 and there I don't have those readings that you refer to.
I hope a LR fellow are showing up with a T4 tomorrow...
 
Case solved for me too.
Haavard Guttormsen drove 100km's to come and help me with an old T4 steam powered computer.
Just as for Hippo, The ECU and Immo was out of sync.
Now the lady start as a dream.
Thanks for your kind feed back and help.

It's good to hear your Freelander is fixed.
 
Yup, so the next I found now, is ABS sensor Left Rear electrical fault.
ABS is ok, 1120ohm but when I check at the ABS unit, its 128ohm...
New cable?
Or is this related to the issue that the only door that opens when I engage the central locking is the drivers door?
The other doors clicks, but nothing else happens...

2 different faults. The locks may be faulty.

The abs should measure correctly at the yellow plug near the sensor. If resistance is out this can be a problem. I would expect the resistance to be the same at the abs unit. Check the sensor cable/connections.
 
Hi,
The ABS sensor are replaced 2 times now.
It measures 1120ohm (I'm an electrician), but if I measure the other end of the signal cable from the LHR ABS sensor, the resistance is only 128ohm...
I've started to remove the front seats to discover and examine the cable, but maybe it's less work to replace ithe entire signal cable. It's a unshielded 0,5qmm cable with 2 leads.
