2001 Kia Sephia L4-1.8L Engine Controls – MIL ON/DTC P1624 Technical Bulletin
The Transmission Control Module (TCM) is not a part of the Engine Control Module
(ECM), but will flash the “HOLD” light and send a “Mil Request Signal” to the ECM when
the TCM has stored a DTC.
This means the ECM will illuminate the Malfunction Indicator “CHECK ENGINE” light
indicating a DTC has been stored. When retrieved, the DTC “P1624 – MIL Request
Signal” will be displayed. This DTC indicates that a code has been stored in the TCM. To
retrieve TCM DTC’s, exit out of the Engine DTC’s Screen, then select “Transmission” to
read ECAT DTC’s.
