Engine Controls - MIL ON/DTC P1624

SOURCE: Kia Technician Times

TITLE: Diagnostic Trouble Code P1624

APPLIES TO: All OBDII Models

SERVICE TIP:






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.
