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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Q43-4 (CB+) - J51-13 (CA+)	Always	Below 1 Ω
   Q43-3 (CGND) - J51-14 (CGND)	Always	Below 1 Ω
   Q43-2 (CV+) - J51-27 (V+)	Always	Below 1 Ω
   Q43-1 (CV-) - J51-28 (V-)	Always	Below 1 Ω
   Q43-4 (CB+) - Body ground	Always	10 kΩ or higher
   Q43-3 (CGND) - Body ground	Always	10 kΩ or higher
   Q43-2 (CV+) - Body ground	Always	10 kΩ or higher
   Q43-1 (CV-) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the J51 connector to the multi-display.
