Output Diagnostic Test Mode (DTM) (Function 03)
(Vehicles From Week 18.99 On)

Output Diagnostic Test Mode (DTM) is used to check the operation of the crash response system. When airbags are triggered, the central locking system switches immediately to "open" and the inside door lock switches are blocked. Emergency flashers and interior lights are switched on and the fuel supply is interrupted.

NOTE:
- Before initiating output Diagnostic Test Mode (DTM), set the central locking system to "closed" by operating the interior switch and start the engine.
- Set interior light switch to "door contact" position.
- After output DTM is initiated, central locking cannot be operated until the DTC memory of the Central Locking Control Module is erased.
