Ignition system, servicing<br />

General notes on ignition system<br />

Note:<br />

Only the components which specifically relate<br />

to the ignition system are dealt with here. For<br />

the other components of the injection and<br />

ignition system <strong>Repair</strong> Group 24.<br />

The Engine Control Module (ECM) is equipped<br />

with On Board Diagnostic (OBD).<br />

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

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

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

Output Diagnostic Test Mode (DTM) Page<br />

01-100 .<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 Engine Control Module (ECM)<br />

could be damaged.<br />

Check DTC memory before carrying out repairs<br />

and for troubleshooting Page 01-23 .<br />

During some checks it is possible that the<br />

control module will detect and store a<br />

Diagnostic Trouble Code (DTC). Therefore after<br />

completing all checks and repairs the DTC<br />

memory must be checked and if necessary<br />

erased Page 01-23 , and then generate the<br />

readiness code Page 01-149 .<br />
