OK: Go to next step 

1. Disconnect the L27 and L57 connectors.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   L27-2 (TC O) - L57-1 (CS)	Always	Below 1 Ω
   L27-2 (TC O) - Body ground	Always	10 kΩ or higher
   L27-12 (HOUR) - L57-9 (HOUR)	Always	Below 1 Ω
   L27-12 (HOUR) - Body ground	Always	10 kΩ or higher
   L27-13 (MIN) - L57-10 (MIN)	Always	Below 1 Ω
   L27-13 (MIN) - Body ground	Always	10 kΩ or higher
   L27-17 (RST) - L57-11 (RST)	Always	Below 1 Ω
   L27-17 (RST) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
