K-ACT ABS (Equipped Models)
Do the 4th step test.
Disconnect the fluid pressure sensor connector and con-
nect the harness adapter [A] between these connectors
Main Harness [B]
Fluid Pressure Sensor [C]
Special Tool - Measuring Adapter: 57001-1700
Connect the digital meter [D] to the harness adapter
Fluid Pressure Sensor Output Voltage
Connections to Adapter:
For Output Fluid Pressure Sensor (Rear Brake)
Meter (+) → W (sensor Y) 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.
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.
Do the 5th step test.
Disconnect the K-ACT ABS hydraulic unit connector and
fluid pressure sensor connector.
Check for continuity between the yellow lead terminal of
the main harness side connector [A] and yellow lead ter-
minal of the main harness side connector [B].
Check for continuity between the black/red lead terminal
of the main harness side connector [C] and black/red lead
terminal of the main harness side connector [D].
If there is the continuity in the lead, replace the K-ACT
ABS hydraulic unit.
If there is not the continuity in the lead, replace or repair
the main harness.
