DESCRIPTION

This DTC is stored when an internal error is detected in the ECM or an STV signal (active brake booster's internal micro switch signal) error is detected.

DTC Code

DTC Detection Condition

Trouble Area

P0575

When STV signal is input and cruise control continues for 0.4 seconds.

When malfunction STV signal is detected for 0.15 seconds.
  • ECM
  • VSC system
  • Wire harness or connector

HINT:

The ECM receives signals from each sensor to control all functions of the cruise control system. When a trouble code is detected, the fail-safe functions until the ignition switch is turned off.
