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

   Standard resistance

   Tester Connection	Condition	Specified Condition
   S35-4 (CB+) - L60-13 (CA+)	Always	Below 1 Ω
   S35-3 (CGND) - L60-14 (CGND)	Always	Below 1 Ω
   S35-2 (CV+) - L60-27 (V+)	Always	Below 1 Ω
   S35-1 (CV-) - L60-28 (V-)	Always	Below 1 Ω
   S35-4 (CB+) - Body ground	Always	10 kΩ or higher
   S35-3 (CGND) - Body ground	Always	10 kΩ or higher
   S35-2 (CV+) - Body ground	Always	10 kΩ or higher
   S35-1 (CV-) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the S35 television camera connector.
