OBD General Information
- The engine control module is equipped with On Board Diagnostics (OBD). Before repairs such as fault finding, check the Diagnostic Trouble Code (DTC) memory first. Also the vacuum hoses and connections must be checked (unmetered air).
- Fuel hoses in engine compartment must only be secured with spring-type clips. The use of clamp or screw type clips is not permissible.
- For the electric components to work properly, a voltage of at least 11.5 Volts is required.
- Do not use sealants containing silicone. Particles of silicone drawn into the engine, will not be burnt in the engine and damage the oxygen sensor.
- The vehicles have a crash fuel shut-off. It reduces the risk of fire in an accident because the fuel pump relay switches the fuel pump off.
- If it is difficult to disconnect the connectors, use a Reversing Light Switch Connector Release Tool T40138.
