Brake Switch "A" Signal Compare Failure (P057162)
DESCRIPTION
When the brake pedal is depressed, the stop light switch assembly sends a signal
to the ECM. When the ECM receives this signal, it cancels the dynamic radar cruise
control. The fail-safe function operates to enable normal driving even if there
is a malfunction in the stop light si ...
