Mobilising the car
| Mobilising the car |
| General |
The car is mobilised as follows:
| • |
When the key is inserted in the ignition and turned to the ST position (+50) to start the car, the car is mobilised when ON (+15 circuit) is passed.
|
|
| • |
The car can also be mobilised with the remote control if the key is first turned to ON and then one of the buttons on the remote control is pressed once. This can be used in the case of a fault on the transponder or “receiver”.
If TWICE does not receive the identity code from the transponder, the message KEY NOT ACCEPTED will be displayed on SID. |
|
| Function |
When the car key is inserted in the ignition switch and turned to the ON position (+15), the antenna unit receives immobilization data, which is sent on to TWICE pin 39. The control module verifies and approves the code and sends it further along the bus. If the code is valid, the engine management system can read it on the bus. The block on the start function is removed and the starter relay draws via pin 4.
