•
Do the 3rd step test.
○
Disconnect the fluid pressure sensor connector.
○
Connect the hand tester [A] to the fluid pressure sensor
connector [B].
Special Tool - Hand Tester: 57001-1394
○
Measure the fluid pressure sensor resistance.
Fluid Pressure Sensor Resistance
For Input Fluid Pressure Sensor (Front Brake)
Connections:
Standard:
If the reading is out of the standard, replace the K-ACT
ABS hydraulic unit.
If the reading is within the standard, replace the K-ACT
ABS hydraulic unit.
•
Do the 4th step test.
○
Disconnect the fluid pressure sensor connector and con-
nect the harness adapter [A] between these connectors
as shown.
Main Harness [B]
Fluid Pressure Sensor [C]
Special Tool - Measuring Adapter: 57001-1700
○
Connect the digital meter [D] to the harness adapter
leads.
Fluid Pressure Sensor Output Voltage
Connections to Adapter:
For Input Fluid Pressure Sensor (Front Brake)
Meter (+) → W (sensor G) lead
Meter (–) → BK (sensor BK/R) lead
○
Measure the output voltage with the engine stopped and
with the connector joined.
○
Turn the ignition switch ON.
Output Voltage
Standard: 0.3 ~ 4.437 V
If the output voltage is not within the specification, pro-
ceed the 5th step.
If the output voltage is within the specification, proceed
the 6th step.
W/R lead [C] ←→ BK/R lead [D]
100 ~ 150 kΩ
