1) The Transmission Control Module (TCM) recognized a malfunction that worsens engine emissions. The Transmission
Control Module (TCM) sends the DTC to the Engine Control Module (ECM), which then switches on the Malfunction Indicator
Lamp (MIL). Notes for Malfunction Indicator Lamp (MIL) Page 01
-3 . The message P1624 is simultaneously stored in the
Engine Control Module (ECM) as evidence that the Malfunction Indicator Lamp (MIL) was not switched on due to an engine
problem but rather a transmission problem.
