System Voltage Circuit Short to Ground or Open (P056014)
DESCRIPTION
The battery supplies power to the ECM even when the ignition switch is off. This
power allows the ECM to store data such as DTC history, freeze frame data and fuel
trim values. If the battery voltage falls below a minimum level, the ECM data is
cleared and the ECM determines that ...
Brake Switch "A" Circuit (P0571)
DESCRIPTION
Detection condition 1:
When the brake pedal is depressed, the stop light switch assembly outputs
a signal to the ECM. When the ECM receives the signal, it cancels control
of vehicle speed by the dynamic radar cruise control system. The fail-safe
function operates to ...
