Distance Control ECU Power Source Circuit

CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: Distance Control ECU Power Source Circuit

Distance Control ECU Power Source Circuit

DESCRIPTION

This circuit provides power to operate the distance control ECU. The distance control ECU determines information about the vehicle in front based on data from the radar sensor, and then decides how much acceleration and / or deceleration is needed to maintain the set distance. The distance control ECU also requests the skid control ECU to apply braking and sound the buzzer.

INSPECTION PROCEDURE

PROCEDURE

1.
CHECK HARNESS AND CONNECTOR (DISTANCE CONTROL ECU - BATTERY AND BODY GROUND)




(a) Disconnect the K13 ECU connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:





(c) Measure the resistance of the wire harness side connector.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
