The P0592 trouble code indicates that there is a low voltage condition detected in the cruise control multi-function input “B” circuit. This means that the signal voltage from the input source, such as the brake pedal switch or clutch pedal switch, is lower than the expected range. The cruise control system relies on accurate input signals to function properly, and a low voltage condition can affect its operation.
