Distance Control ECU Power Source Circuit

DESCRIPTION

This circuit provides power to operate the distance control ECU (cruise 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 to sound the buzzer.

INSPECTION PROCEDURE

1. CHECK DISTANCE CONTROL ECU

1. Disconnect the distance control ECU connector.

2. Measure the voltage according to the value(s) in the table below.

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   J17-1 (B) - Body ground	Engine switch on (IG)	10 to 14 V

3. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   J17-10 (SGND) - Body ground	Always	Below 1 Ω
   J17-12 (GND) - Body ground	Always	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
