METER / GAUGE SYSTEM Clock Display Circuit

DESCRIPTION

The accessory meter assembly uses this circuit to communicate with the combination meter assembly via the direct line. The accessory meter assembly uses this circuit to receive the drive monitor switch signals from the combination meter assembly via the direct line and multi-information display signal from each ECU through the combination meter assembly via the direct line.

3. CHECK HARNESS AND CONNECTOR (ACCESSORY METER ASSEMBLY - COMBINATION METER ASSEMBLY)

   
   

   1. Disconnect the E2 and F5 connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition F5-2 (HSI+) - E2-4 (LCL+) Always Below 1 Ω F5-12 (DATA) - E2-5 (MDAT) Always Below 1 Ω F5-6 (SYNC) - E2-17 (SYNC) Always Below 1 Ω E2-4 (LCL+) - Body ground Always 10 kΩ or higher E2-5 (MDAT) - Body ground Always 10 kΩ or higher E2-17 (SYNC) - Body ground Always 10 kΩ or higher F5-16 (SGND) - Body ground Always Below 1 Ω

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

5. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - DRIVE MONITOR SWITCH)

   
   

   1. Disconnect the E2 and D3 connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition E2-6 (A/B) - D3-5 (INFO) Always Below 1 Ω E2-6 (A/B)- Body ground Always 10 kΩ or higher E2-7 (RSET) - D3-6 (SEL) Always Below 1 Ω E2-7 (RSET) - Body ground Always 10 kΩ or higher E2-18 (E) - D3-7 (STUP) Always Below 1 Ω E2-18 (E)- Body ground Always 10 kΩ or higher D3-3 (E) - Body ground Always Below 1 Ω

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

6. INSPECT DRIVE MONITOR SWITCH

   
   
   1.
