17-42 ELECTRICAL SYSTEM
Ignition System
II. Connections to Connector (5 V circuit)
Vehicle-down Sensor Lead Connector [A] (harness side)
Digital Volt Meter [B]
Meter (+) → Connector Y/G Lead [E]
Meter (–) → Connector BK/Y Lead [D]
•
Turn the ignition switch ON, and measure the power
source voltage.
Vehicle-down Sensor Power Source Voltage
Standard:
about 5 V
•
Turn the ignition switch OFF.
If there is no standard voltage, check the following:

Wiring for Vehicle-down Sensor Power Source
Vehicle-down Sensor Output Voltage
•
Remove the vehicle-down sensor (see Vehicle-down
Sensor Rem oval).
•
Connect the vehicle-down sensor [A] to the connector of
the harness.
•
Hold the sensor almost vertical [B] with the arrow mark
pointed up.
•
Connect:
Vehicle-down Sensor Lead Connector [C]
Digital Volt Meter [D]
Needle Adapters [E]
Special Tool - Needle Adapter Set: 57001-1457
Connection to Connector (5 V circuit)
Meter (+) → Connector Y/G Lead [F]
Meter (–) → Connector BK/Y Lead [G]
•
Turn the ignition switch ON, and measure the output volt-
age with the connector joined.
Vehicle-down Sensor Power Output Voltage
Standard: 0.4 ∼ 1.4 V (with sensor arrow mark
pointed up)
•
Tilt the sensor 60 ∼ 70° or more [H] right or left, and mea-
sure the output voltage.
○
The time lag is from 0.5 to 1 second.
Vehicle-down Sensor Power Output Voltage
Standard: 3.7 ∼ 4.4 V (with sensor tilted 60 ∼ 70° or
more, right or left)
If the output voltage is out of the specified, replace the
vehicle-down sensor.
