CHANGING THE AIR BAG COMPUTER

Air bag computers are sold locked to prevent any risk of incorrect triggering (all trigger lines are
inhibited). This "locked" mode is indicated by illumination of the warning light on the instrument panel.

When changing an air bag computer, follow the instructions below:

- Ensure that the ignition is switched off.

- Change the computer.

- Carry out a check using the fault finding tool.

- If necessary, change the computer configuration using the "computer configuration"command .

- Unlock the computer, only when no fault is declared by the fault finding tool.
