Inspection Procedure

WARNING: This page is about a different car, the 2006 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK HARNESS AND CONNECTOR (ECM - BATTERY) 
    1. Turn the ignition switch off.
    2. Disconnect the ECM connector.
    3. Measure the voltage according to the value(s) in ECM - BATTERY (3MZ-FE)  and ECM - BATTERY (2AZ-FE)  .

      Standard voltage: 

      3MZ-FE 

      ECM - BATTERY (3MZ-FE)

      Tester connection Condition Specification
