General Data

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.

Radio


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
If the car battery has to be replaced the siren function should be disabled.


NOTE: Earlier types of siren with rechargeable batteries could be turned off with the key supplied. This is not the case on cars where Guard Alarm II has been installed.


To disable the siren function on the new alarm proceed as follows:
- Disarm the alarm system
- Turn the ignition ON and then OFF
- Disconnect the battery leads within 15 seconds of the ignition being turned off

The alarm siren will be on-line again when the battery leads are reconnected to the battery.
