4. CHECK HARNESS AND CONNECTOR (REAR SWITCH LH - REAR MOTOR LH)

   
   

   1. 

      Disconnect the O18 switch connector.

   2. Disconnect the O19 motor connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition O18-4 (AUTO) - O19-4 (AUTO) Always Below 1 Ω O18-4 (AUTO) or O19-4 (AUTO) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

5. INSPECT REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY (for LH)
