HISS programming

[Sprint]

If you find yourself needing to program a new key... Haynes workshop manuals have the relevant information for the HISS registration process.

Only the ignition pulse generator wiring loom plug position changes from model to model, the programming routine is common AFAIK.

You will need one original key... lose that and you're up for an ECU and key set. If you're down to one key - do something about it!

Care to share the procedure with us?

1. Obtain a new transponder key.
2. Grind the key in accordance with the shape of the original key (no shit!).
3. Apply a 12v battery voltage to the ignition pluse generator lines of the ignition control module (ICM) using the special tool (ignore this, it can be done/bodged at home).
4. Turn the ignition switch ON with the original key. The immobiliser indicator comes on and it remains on.
4a. The code of the original key is recognised by the ICM.
4b. If there is any problem in the system, the system will enter diagnostic mode (displaying the diagnostic code)
5. Disconnect the red (+'ve) for two seconds or more, then connect it again. The indicator comes on, then blinks four times repeatedly.
5a. The ICM is now in registration mode.
6. Turn the ignition switch OFF and remove original key.
7. Turn the ignition switch ON withnew key or spare key. The indicator comes on and then blinks four times repeatedly.
7a. The new key is now registered with the ICM.
7b. If there is any problem with registration, the system will enter diagno... you get the picture.
8. Repeat steps 6 & 7 for up to 3 extra keys.
9. Turn OFF the ignition. Remove the special tool (or the bodgy thing you used at home!). Reconnect the pulse generator plug ends.
10. Profit. Send all gratuitous payment cheques to Tyson for W.F.A. fund.
