Air Bag Control Module: Vehicle Damage Warnings
Before Changing A Control Module
Experience has shown that control module components that have been returned for repairs while under warranty are really fault-free. In these cases,
replacing the control module has not remedied the fault. Thus, go through the following points before replacing the control module:
1. Check the last issue of TIS2000 to see if the problem in question could be remedied by a software update for the control module (for control
modules that allow reprogramming).
2. Check all grounding points and the power supply to the control module.
3. Use the diagnostic tool to check that all read values are reasonable (several read values can affect one function).
4. Use the diagnostic tool to check that all activations work (a fault in an output circuit can affect another output circuit).
5. If the fault remains, the control module must be replaced.
