DTC No. | Detection Item |
DTC Detection Condition | Trouble Area | |
P0575 | Cruise Control Input Circuit |
Either of the following conditions is met:
- When the ignition switch is ON, STP signals received by the ECM
supervisory CPU and that received by the control ECU do not match for
approximately 0.2 seconds or more.
- While the dynamic radar cruise control system is operating, the dynamic
radar cruise control system control of vehicle speed is not canceled and
approximately 0.4 seconds have elapsed after cruise cancel signal (STP
signal) is received by the ECM.

NOTICE: Before replacing the ECM, refer to Registration. Click here
 HINT: The
ECM receives signals from each sensor to control all functions of the
cruise control system. When a malfunction is detected, the fail-safe
function operates until the ignition switch off. PROCEDURE

CHECK FOR DTCs (RADAR CRUISE1) | (a) Clear the DTCs.
Click here (b) Perform the following to make sure that the DTC detection conditions are met.
HINT: If the detection conditions are not met, the malfunction cannot be detected.
- Drive the vehicle at a speed for which dynamic radar cruise control operation is possible.
- Turn the cruise control system on using the cruise control main switch (ON-OFF button).
- Depress the brake pedal for 0.4 seconds or more.
