Air Bag Control Module: Service Precautions

ABA. Control Modules






Connecting and disconnecting control modules

The ignition must always be switched off when connecting and disconnecting the control modules, connectors and breakout box. The ignition should also be switched off when measuring with the ohmmeter.


Temperature






The control modules must not be heated above 80 °C. Remove the control modules when for example baking paint.


Arc welding

Always remove the battery negative lead, to prevent closed circuits occurring. Position the welding ground as close to the welding site as possible, otherwise different ground potentials could be generated in different components. If welding is to take place in the immediate vicinity of a control module, the control module must be removed to avoid heat damage.

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.


ABB. 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.


ABC. Alarm






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


ABD. Symbols






Images and symbols are used at certain points in the trouble-shooting instead of or to supplement the text, to simplify the manual and make it easier to read
