SELF-DIAGNOSIS SYSTEM 17-53
Vehicle-down Sensor (Service Code 31) (DTC C0064)

• Hold   the sensor vertically.
• with the connector
  Measure     the output voltage with the engine stopped and
                        joined.
• Tilt the sensor 60  70° oron.more [A] right or left, then hold
  Turn   the ignition switch
• the sensor almost vertical with the arrow mark pointed up
  [B], and measure the output voltage.
  Output Voltage
   Standard: With sensor tilted 60  70° or more right or
               left: DC 0.65  1.35 V
                 With sensor arrow mark pointed up: DC
                 3.55  4.45 V

• Turn  the ignition switch off.
  If the reading is out of the standard, replace the sensor.

 If the reading is within the standard, remove the ECU and
 check the wiring for continuity between harness connec-
 tors.
○Disconnect the ECU and sensor connectors.
  Wiring Continuity Inspection
   ECU Connector [A] ←→
      Vehicle-down Sensor Connector [B]
        ECU Terminal 50 [C] ←→ Sensor Terminal [D]
        ECU Terminal 16 [E] ←→ Sensor Terminal [F]
  If the wiring is good, check the ECU for its ground and
  power supply (see ECU Power Supply Inspection(3-39)).
  If the ground and power supply are good, replace the
  ECU.
