Check Body Integrated Unit Power Supply And Ground Circuit

STEP CHECK SHEET

Step	Check	Yes	No
1. CHECK POWER SUPPLY OF BODY INTEGRATED UNIT. Disconnect the harness connector of body integrated unit. Measure the voltage between the harness connector terminal and chassis ground. Connector & terminal (B280) No. 7 (+) - Chassis ground (-): (B281) No. 2 (+) - Chassis ground (-):	Is the voltage more than 10 V?	Go to step 2.	Check the harness for open or short between body integrated unit and fuse.
2. CHECK BODY INTEGRATED UNIT GROUND CIRCUIT. Disconnect the harness connector of body integrated unit. Measure the resistance between the harness connector terminal and chassis ground. Connector & terminal (B280) No. 22 - Chassis ground: (B281) No. 8 - Chassis ground: (B281) No. 9 - Chassis ground:	Is the resistance less than 10 Ω?	Check the body integrated unit. < Ref. to , BASIC DIAGNOSTIC PROCEDURE . >	Repair the harness.
