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) -K83-. Check Malfunction Indicator Lamp (MIL) -K83-   Page 01
-3 . The message P1624 is simultaneously 
stored in the Engine Control Module (ECM) as evidence that the Malfunction Indicator Lamp (MIL) -K83- was not switched on 
due to an engine problem but rather a transmission problem.
