Description
While driving with the cruise control, if the ecm detects that the brake pedal is depressed, the cruise control operation will be canceled. The stop light switch sends brake pedal status signals to the ecm.
When the brake pedal is not depressed, terminal st1- is equal to the positive (+) battery voltage and terminal stp is below 1 v. When the brake pedal is depressed, the ecm cancels cruise control operation.
The ecm outputs this dtc when the voltage of terminals st1- and stp are both below 1 v for 0.5 Seconds or more at the same time. The fail-safe function operates to enable normal driving even if there is a malfunction in the stop light signal circuit.
