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

   Standard resistance

   Tester Connection	Condition	Specified Condition
   E11-9 (CLK) - E1-36 (MCLK)	Always	Below 1 Ω
   E11-10 (DATA) - E1-37 (MDAT)	Always	Below 1 Ω
   E11-11 (SYNC) - E1-38 (SYNC)	Always	Below 1 Ω
   E11-9 (CLK) - Body ground	Always	10 kΩ or higher
   E11-10 (DATA) - Body ground	Always	10 kΩ or higher
   E11-11 (SYNC) - Body ground	Always	10 kΩ or higher
   E11-16 (SGND) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the E1 connector.
