DTC |
P057162 |
Brake Switch "A" Signal Compare Failure |
DESCRIPTION
When the brake pedal is depressed, the stop light switch assembly outputs a signal to the ECM. The ECM uses this signal to control cancellation of vehicle speed by the dynamic radar cruise control. When the ECM determines that terminals STP and ST1- of the stop light switch assembly are both less than 1 V, DTC P057162 is stored.
