SUBJECT

MODEL
F01
F02
F10
F25
Vehicles with option code 302 (Anti­theft Alarm System)
SITUATION
When the panic button is pressed on the remote control key for 3 seconds or more, the alarm siren does not sound. Only the 4­way
flashers come on.
CAUSE
Software error in the FZD module (Roof Function Center)
This error only occurs when the vehicle is programmed with ISTA/P2.47.7 or 2.48.1
PROCEDURE
Do not replace parts.
1.
2.
Perform diagnosis using the latest ISTA diagnostic software version. Complete all test plans for any stored faults in the DWA
(Anti­theft Alarm System). If no faults are stored proceed to the next step.
Note:
When the ISTA system message displays: "Battery voltage only "XX.XX" V. Please connect charger." Please note the displayed
battery voltage reading in the repair order comments section.
Reprogram the vehicle using ISTA/P 2.48.2 or higher. For example, if the vehicle was programmed with ISTA/P2.48.1, the
measures plan will only include the FZD module for new coding. The new I­Levels included in 2.48.2 are as follows:
^ F01, F02: F001­12­11­503
^ F10: F010­12­11­503
^ F25: F025­12­07­509
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology /
