Tech Tips

If DTC P0575 is stored while the cruise control is in operation, the master cylinder solenoid (skid control ECU) clears the stored vehicle speed in the ECM and cancels the cruise control operation. At the same time, the cruise control indicator light blinks to inform the driver of the malfunction. When this trouble code is stored, fail-safe remains on until the engine switch is turned off.
