Ignition System, General Information

• For the electric components to work properly, a voltage of at least 11.5 Volts is required.
• The battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module (ECM) can otherwise be damaged.
• Engine Control Module (ECM) is equipped with On Board Diagnostic (OBD).
• It is possible that the control module will recognize a malfunction and store a DTC during some tests. Therefore the following work steps must be performed in the mentioned sequence after ending all tests and repairs.

• Check DTC memory → Diagnostic Mode 03 - Read DTC Memory .
• Erase DTC memory → Diagnostic Mode 04 - Erase DTC Memory .
• For completion, generate readiness code → Readiness Code, Generating .
