The Motronic Engine Control Module (ECM) -<br />

(OBD). Before carrying out repairs and<br />

troubleshooting the DTC memory must be<br />

checked. Also the vacuum hoses and<br />

connections must be checked (unmetered air).<br />

Fuel hoses in engine compartment must only<br />

be secured with spring-type clips. The use of<br />

clamp or screw-type clips is not permitted.<br />

Components marked with * are checked via On<br />

Board Diagnostic (OBD) Page 01-23 .<br />

Components marked with **can be checked via<br />

Do not use sealing compounds containing<br />

silicone. Particles of silicone drawn into the<br />

engine, will not be burned in the engine and<br />

may damage the Oxygen Sensor(s) (O2S).<br />

For trouble-free operation of the electrical<br />

components, a voltage of at least 11.5 V is<br />

necessary.<br />

Disconnecting and connecting the battery must<br />

only be done with the ignition switched off,<br />

otherwise the Motronic Engine Control Module<br />

(ECM) -J220- could be damaged.<br />
