Cruise Control System
DIAGNOSTIC TROUBLE CODE CHARTIf an error code is displayed during the DTC check check the circuit listed for that code in the table.
P0500/21, 23 - P1566/54:
W/o Adaptive laser cruise control system
P0500/21, 23 - P1576/67:
P1577/68 - P1572/75:
W/ Adaptive laser cruise control system
HINT:
*: When DTC P1576 (67), P1577 (68) and/or P1578 (69) is output, check the skid control ECU for DTC in the diagnosis mode. Only when any code is output, inspect the trouble area according to the DTC. For P1576 (67) and P1577 (68) especially, if no DTC is detected in the skid control ECU, the DTC may be caused by the driving condition with adaptive radar cruise control, such as a case of driving on a road with consecutive curves immediately after starting the vehicle.
Provide your customers with the information that the radar cruise control will not properly function if he/she drives the vehicle on a road with consecutive curves and does not drive straight immediately after start. Because the steering sensor or yaw rate sensor itself is not regarded as faulty in this case, its replacement is not necessary.
Clear the DTC and recheck the operation on an ordinary road (radar cruise control).
