recognized after the engine has been restarted. Significance of MIL Page 01

Note for malfunction P1624:

MIL stands for Malfunction Indicator Light. Once the Engine Control Module (ECM) recognizes a malfunction that
decreases the exhaust emissions it switches the MIL on.
The MIL is switched on only by the Engine Control Module (ECM), since the ECM has the only connection to the MIL..
Malfunction that decrease the exhaust emissions can also be recognized by the Transmission Control Module (TCM),
These malfunction are also indicated by the MIL.
