Alarm Module: Service Precautions

Control Modules

Connecting Disconnecting Control Modules






Always switch off the ignition before connecting or disconnecting a connector or the test box to a control module.


Temperature






The control module must not be heated to above 80° C. Remove control module when stoving for example.

Arc Welding

Disconnect connector from control modules when arc welding. Remove control module before carrying out any arc welding work close to it.

Replacing

Do not replace a control module without checking its wiring and components. The new component may be damaged in the same way as the old one.


NOTE: Make a note of the radio code before disconnecting the battery leads and the car is without voltage supply. Re-enter the code when the work has been completed.



Alarm






When replacing the battery on cars with the new VGLA alarm, the siren does not need to be disconnected.



Symbols





Figures and symbols are used instead of, or to supplement text to facilitate fault-tracing and make easier to read.
