Brake switch "A" / "B" correlation
Description
The stop light switch is a duplex system that transmits two signals: stp and
st1-. These two signals are
used by the ecm to monitor whether or not the brake system is working properly.
If the signals, which
indicate the brake pedal is being depressed and released, are detected ...
