K-ACT ABS (Equipped Models)
Do the 6th step test.
Recheck the service code indication; erase the service
code, perform the pre-diagnosis inspection 1 and 2, and
retrieve the service code.
If the K-ACT ABS indicator light (LED) [A] lit, faulty input
fluid pressure sensor (rear brake) in the K-ACT ABS hy-
draulic unit. Replace the K-ACT ABS hydraulic unit.
If the K-ACT ABS indicator light (LED) unlit, K-ACT ABS
is normal (service code is not stored; temporary failure.).
Input Fluid Pressure Sensor (Rear Brake) Offset
Abnormal (Service Code 86)
Do the 1st 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 hand tester [D] to the harness adapter leads.
Special Tool - Hand Tester: 57001-1394
Fluid Pressure Sensor Input Voltage
Connections to Adapter:
For Input Fluid Pressure Sensor (Rear Brake)
Hand Tester (+) → R (sensor W/R) lead
Hand Tester (–) → BK (sensor BK/R) lead
Measure the input voltage with the engine stopped and
with the connector joined.
Turn the ignition switch ON.
Standard: 4.5 ~ 5.2 V
If the input voltage is not within the specification, proceed
the 2nd step.
If the input voltage is within the specification, proceed the
