Vehicle-down Sensor Input Voltage Inspection


Vehicle-down Sensor Input Voltage Connections to Adapter: Digital Meter (+) → R (sensor BL) lead Digital Meter (–) → BK (sensor BR/BK) lead

Vehicle-down Sensor Input Voltage Inspection


Input Voltage Standard: DC 4.75 5.25 V


If the reading is within the standard, check the output voltage (see Vehicle-down Sensor Output Voltage Inspection).

If the reading is out of the standard, remove the ECU and check the wiring for continuity between main harness connectors.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and sensor connectors.
