  2. CHECK COMBINATION METER SYSTEM 
    1. Inspect the circuits that send vehicle speed signals to this system in the meter system. Refer to Speed Signal Circuit .
    2. During inspection for the meter section, if there is an instruction that indicates to go back to inspections for each system, proceed to the next step.

    NEXT: Go to next step 

  3. CHECK HARNESS AND CONNECTOR (ECM - COMBINATION METER) 
    1. Disconnect the ECM connector.
    2. Disconnect the combination meter connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)

      Tester Connection Condition Specified Condition
      C50-32 (+S) - A35-15 (SPD) Always Below 1 Ω

    NG → See step   4 

    OK → See step   6 

  4. CHECK HARNESS AND CONNECTOR (ECM - JUNCTION CONNECTOR) 
    1. Disconnect the ECM connector.
    2. Disconnect the junction connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)

      Tester Connection Condition Specified Condition
      C58-7 - A35-15 (SPD) Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - JUNCTION CONNECTOR)
