TCL Light On and DTC U1120 - 2004-on Galant & Endeavor, 2006-on Eclipse. The TCL and TCL OFF indicator lights may come on with CAN Bus DTC U1120 stored in PCM memory. First check for and diagnose any stored or pending MFI DTCs. DTC U1120 usually indicates that an MFI DTC is stored, and the Traction Control system recognizes that there is an error in the PCM data. Repairing the MFI DTC concern should allow the CAN Bus DTC U1120 to be cleared.
