S2 Wont Start. Starter/immobiliser Advice Needed Please!

[prayforsnow]

Hi,

 

I need some advice please. My s2 111s won't start. I have tried replacing the starter motor but now I think it is the immobiliser but I'm not sure.

 

If I try to arm the car with the fob, the lights will flash twice and the siren will instantly sound. If I leave the car alone it will automatically arm after 45 secs and then I can press button A on the fob and dearm. Usually after a few minutes the alarm will beep 5 times - I can't find anywhere on the web that tells me what 5 beeps is!

 

A few weeks ago tried to diagnose problem with a friend. We thought it must be the starter motor, as when I turned the ignition, you could hear a click and the fuel pump primed and we managed to bump start it - which I thought if the immobiliser issue was a real problem, it wouldn't have let us do

 

So this week I replaced the starter motor but now when I turn ignition I get the click but the fuel pump does not prime. Checked the fuses also and there was a blown one for the start immobiliser which I've replaced.

 

Have tried all this with a known good battery and also checked fuel inertia switch.

 

I'm desperate, so any advice appreciated or if anyone knows of an alarm/electrical specialist that can come to your home please let me know

 

Thanks

 

Greg

I Imagine a Lotus Dealer will supply pin if you have proof of ownership.

 

I seem to recall its best not to use the manual. I have some instructions somewhere, will look.

 

How to program a key fob

 

 

 

OK, I had some trouble with this recently and two dealers told me it was "very hard" and even the Lotus Rep had trouble. Once I figured out that Lotus had left out a step or two in the owners manual it was not so bad. I thought I would post this for those of you who may have to replace your batteries or just want to program a new fob:

 

What Lotus left out, I found in the Alarm manual, and added some from experience:

 

Start procedure with ignition on and the alarm DISARMED.

 

Follow owners manual instructions:

 

Press and hold both buttons on fob until FOB light stops flashing (about 10 seconds). Do this for all remotes to be programmed (Yes even the one that works because this will reset all to a new code). After this the light of the fob should stay on until after programming. This is the last step where the fob light matters, all else concerns the TACH light.

 

Turn ignition off and on three times fast (within a few seconds) stop in the off position

 

The TACH light will illuminate for 3 seconds then go out.

 

Enter your alarm code as per the book. Basically turn on the ignition, count the number of flashes to correspond with the first number of the code and turn off the ignition. Do this for each number of the code. (I would suggest doing this first with the alarm ARMED to see if it DISARMS, that way you at least know you have the correct code and you are able to enter it correctly).

 

My technique for this that worked well was turn on ignition as fast as possible, wait for the light count, turn off ignition when light illuminated on the count of your number (don't wait for the light to go out-for some reason mine would disarm the alarm either way but worked better this way to program a new fob). Between code number entries turn ignition off and wait about a second (you can hear a click from the engine bay about a second after turning off the ignition). Then repeat above for each number of your code.

 

(Manual says if wrong number is entered wait 10 seconds then resume with 1st number of code but I would recommend starting over, unless you really feel lucky)

 

After the last number is entered and you turn off the ignition you have to turn the ignition back on and if all goes well (say a prayer to Colin if you made it this far) you should have a STEADY illuminated TACH light.

 

Press and hold the #1 (large) key fob button on one of the remotes until the TACH light goes out then comes back on.

 

Do this for each remaining fob, should be able to do a total of 4 per the book.

 

Each one should give the same indication as above.

 

Turn off the ignition and check each fob for function.

 

That should do it and by the way if it does not work don't fear I found that even after many unsuccessful, incorrect attempts, my original fob never lost its program and would still work.

 

Good luck and I hope this helped.

 

 

Programming Additional Transmitter Fobs

Two transmitter fobs are provided with the new car. If one transmitter is lost or damaged, a replacement should be obtained immediately from your dealer, and programmed to the car alarm controller using a functioning transmitter fob and the system owner’s unique Personal Identification Number (PIN).

Up to 4 transmitter fobs can be matched with the alarm system, but all fobs must collectively undergo the single programming operation:

 

a). Before programming the transmitters, the PIN should first be verified. If the PIN is incorrect and a working fob is prepared for reprogramming, all fobs may be disabled. To verify the PIN;

With the car immobilised (tell tale flashing), follow steps (3i) to (3iii) below (ie. do not prepare any fobs). If the PIN is correct, the tell tale should be extinguished, and the system mobilised. If not, the PIN is incorrect.

. Having verified the PIN as above, proceed as follows:

 

1. Press, simultaneously, both buttons on a transmitter fob until the fob tell tale stops flashing (approx. 10 seconds). On release of the buttons, the fob tell tale will light.

2. Repeat operation (1) for ALL the transmitter fobs required to operate the system.

3. If the system is immobilised (security tell tale flashing):

(i) Turn the ignition on and off 3 times within 7 seconds; the security tell tale in the tachometer will light for 3 seconds.

(ii) Enter the PIN: Immediately the tell tale goes out, switch ON the ignition and count the number of security tell tale flashes until equal to the first number of the PIN, then turn the ignition OFF, then back ON again.

(iii) Repeat operation (ii) for the remaining 3 digits of the PIN, remembering to tum the ignition OFF and back ON after each code number.

Note: If at any time a mistake is made when entering the PIN, turn the ignition OFF for 10 seconds and recommence entering the PIN.

(iv). If the PIN is correct, the security tell tale will be out. Carry on with step 4.

4. With the system mobilised (security tell tale out):

(i) Turn the ignition on and off 3 times within 7 seconds; the security tell tale in the tachometer will light for 3 seconds.

(ii) Enter the PIN: Immediately the tell tale goes out, switch ON the ignition and count the number of security tell tale flashes until equal to the first number of the PIN, then turn the ignition OFF, then back ON again.

(iii) Repeat operation (ii) for the remaining 3 digits of the PIN, remembering to turn the ignition OFF and back ON after each code number.

Note: If at any time a mistake is made when entering the PIN, turn the ignition OFF for 10 seconds and recommence entering the PIN.

5. After finishing step (4) with the ignition on, within 7 seconds, press once the large button of each transmitter fob.

6. Turn off the ignition.

7. Test operation of each transmitter fob.
