2. CHECK HARNESS AND CONNECTOR (CLOCK ASSEMBLY - COMBINATION METER)

   
   

   1. 

      Disconnect the E9 and E1 connectors.

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

      Standard resistance
      Tester Connection Condition Specified Condition E9-9 (CLK) - E1-36 (MCLK) Always Below 1 Ω E9-10 (DATA) - E1-37 (MDAT) Always Below 1 Ω E9-11 (SYNC) - E1-38 (SYNC) Always Below 1 Ω E9-9 (CLK) - Body ground Always 10 kΩ or higher E9-10 (DATA) - Body ground Always 10 kΩ or higher E9-11 (SYNC) - Body ground Always 10 kΩ or higher E9-16 (SGND) - Body ground Always Below 1 Ω

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

3. INSPECT COMBINATION METER ASSEMBLY

   
   

   1. 

      Reconnect the E1 connector.
