Teaching Hand-Held Transmitter





Teaching Hand-Held Transmitter

General

Up to four hand-held transmitters can be adapted to the control module. The hand-held transmitter is used to operate the central locking system and to open the luggage compartment (front lid). Furthermore, the stored seat, mirrors and lumbar support positions are set when the vehicle is unlocked with the hand-held transmitter. Also refer to Seats - Testing and Inspection - "Control module function - seat memory System S 02". Another function is the immobilizer which operates by means of the integrated transponder.

Work preparation

The following information is required to teach the hand-held transmitter:
- Key learning code from IPAS
- 24-digit Code No. (see barcode label on key grip)
- If the key is stolen or the hand-held transmitter is faulty, all keys still in the customer's possession will be required.


NOTE:
- During maintenance work, please bear in mind that the transmission frequency of the hand-held transmitter is different according to the country of use. The corresponding reception frequency is printed on the alarm system control module. This reception frequency is either;
- 433 MHz with M-number M534
- 315 MHz with M-Number M535; refer to the Allocation Table in Coding for country coding.


Procedure

1. Connect the vehicle keys and the new hand-held transmitter and insert in the ignition.
2. Connect PST2 and switch on ignition.
3. Select "Alarm system" in the menu and press the double arrow key [>>].
4. Select "Learning function" in the menu and press the double arrow key [>>].
5. Select "Transponder key" in the menu and press the double arrow key [>>].
6. "Input key learning code" appears on the screen. Input the key learning code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
7. "Please confirm input" appears on the screen. Check the input and press the [F7] key to confirm the input.
8. Distinguish between loss and fault and additional hand-held transmitter for the transponder.
8a) Teaching an additional hand-held transmitter
Select a tree position (1, 2, 3 or 4) with the arrow key [down arrow] and press the [F8] key.
Now the transponder code is saved in the selected position
Note the position of the new transponder code.
8b) Teaching in the case of a lost or faulty hand-held transmitter:


CAUTION:
Risk of theft due to the lost hand-held transmitter.
- It is essential to delete the transponder code of the lost hand-held transmitter as described in step 8 b).
- It is essential to delete the radio code of the lost hand- held transmitter as described in step 12 b).



NOTE: The adjustment function of the seat, mirror and lumbar positions via the hand-held transmitter is correct only if the radio code and the transponder code of a hand-held transmitter are each stored at the same position in the alarm system control module.


8b) Teaching in the case of a lost or faulty hand-held transmitter:
In this case, it is first necessary to identify and delete the stored transponder code of the lost or faulty hand-held transmitter. All remaining vehicle keys are required for this purpose, because all transponder codes are erased during the deletion function.
The vehicle code of the vehicle key is displayed under "Current transponder".
Press the [F3] key. "All codes will be deleted" appears on the screen; confirm with the [F7] key.
Insert the vehicle key equipped with the new hand-held transmitter Into the ignition lock and switch on the ignition. Establish communication between the PST2 and the control module. Select the position (1, 2, 3, or 4) with the arrow keys [up arrow] and [down arrow] and press the [F8] key. The transponder code of the first hand-held transmitter has now been taught. Remove the key and repeat the process with the remaining hand-held transmitters.
9. Press the double arrow key [<<], select menu item "Remote control" and press the double arrow key [>>].
10. "Input key learning code" appears on the screen. Input the key learning code with the arrow keys [up arrow] and [down arrow] and press the double arrow key [>>].
11. "Please confirm input" appears on the screen. Check the input and press the [F7] key to confirm the input.
12. Distinguish between loss and fault and additional hand-held transmitter for the radio code.
12a) Teaching an additional hand-held transmitter:
Select the same position (1 to 4) as for the transponder key and press the [F8] key.
12b) Teaching in the case of a lost or faulty hand-held transmitter:
In this case, it is first necessary to identify and delete the stored "radio code" of the lost or faulty hand-held transmitter. The remaining hand-held transmitters are required for this purpose.
Press the locking button on the hand-held transmitter and then insert the vehicle key into the ignition lock, switch on the ignition and re-establish communication with the control module.
The radio of the hand-held transmitter with which the vehicle was last unlocked is displayed under "Current radio code".
Compare this radio code with the radio codes at positions 1 to 4. This comparison allows the position of the lost hand-held transmitter (radio code) to be identified, as one radio code is ultimately left over at positions 1 to 4. Insert the vehicle key equipped with the new hand-held transmitter into the ignition lock and switch on the ignition Establish communication with the control module. Select the identified position with the arrow keys [up arrow] and [down arrow] and delete the radio code with the [F3] key. Then press the [F8] key.
13. Carefully input the 24-digit code number with the arrow keys [up arrow] and [down arrow] press the double arrow key [>>].
14. "Please confirm input" appears on the screen. Check the input and press the [F7] key.
15. Now the handheld transmitter is taught. Go back to the menu item "Learning function", remove the key and switch on the ignition again. Once the key has been removed again, the hand-held transmitter is ready for use. Check handheld transmitter for operation.
