Terminal Voltage Inspection
1.Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)
2.Remove the sensor cover.(See SENSOR COVER REMOVAL/INSTALLATION.)
3.Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)
4.Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
-
• If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s).
-
― If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the indicator unit. (See INDICATOR UNIT REMOVAL/INSTALLATION.)
