TCL DIAGNOSTIC TROUBLE CODE DETECTION CONDITIONS
M1354003500048
TCL diagnostic trouble codes (TCL DTCs) are set
under different conditions, depending on the
malfunction detected. Most TCL DTCs will only be
set during vehicle operation. Some TCL DTCs will
also be set during the TCL self-check immediately
after the engine is started. When you check if an TCL
DTC will be displayed again after the DTC has been
erased, you should recreate the TCL DTC set
conditions. Depending on the detection timing and
set conditions for the specific TCL DTC, you must
either drive the vehicle or turn the engine off and
restart it. To set the proper conditions for that DTC
again, refer to "TCL DTC SET CONDITIONS" for
each TCL DTC that you are trying to reset.
