DESCRIPTION

When the ECM detects an internal malfunction, DTC P057504 or P057549 is stored.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	DTC Output from
P057504	Cruise Control System Internal Failure	When the dynamic radar cruise control system is operating, the ECM detects a malfunction in the internal cancel circuit for 0.4 seconds or more.	ECM	Radar Cruise1
P057549	Cruise Control Internal Electronic Failure	When the dynamic radar cruise control system is operating, the ECM detects a malfunction in the internal STP signal circuit for 0.2 seconds or more.	ECM	Radar Cruise1

CAUTION / NOTICE / HINT

NOTICE:

Before replacing the ECM, refer to Service Bulletin.

PROCEDURE

CLEAR DTC

(a) Clear the DTCs.

Powertrain > Radar Cruise1 > Clear DTCs

2.	CHECK FOR DTCs

(a) Make sure that the DTC detection conditions are met.

HINT:

If the detection conditions are not met, the system cannot detect the malfunction.

(b) Check for DTCs.

Powertrain > Radar Cruise1 > Trouble Codes

Result	Proceed to
DTC P057504 and P057549 are not output.	A
DTC P057504 or P057549 is output.	B

USE SIMULATION METHOD TO CHECK

REPLACE ECM
