If the fuse is good, check the wiring continuity as follows.
Disconnect: Battery Positive Cable (see Battery Removal in the Electrical System chapter) KIBS Hydraulic Unit Lead Connector (see KIBS Hydraulic Unit Removal in the Brakes chapter)
Check the wiring continuity between the positive cable terminal [A] of the battery and R/W lead terminal [B] in the KIBS Hydraulic Unit Lead Connector [C].
If the wiring is open, replace or repair the harness (see KIBS System Circuit in the Brakes chapter).
If the wiring is good, go to next step.
The KIBS motor relay is built in the KIBS Hydraulic Unit.
Therefore the relay cannot be checked directly.
If this service code appears even if all checks are ended, replace the KIBS hydraulic unit.
If the service code does not appear, the KIBS system normal (temporary failure).
Front, Rear Wheel Rotation Difference Abnormal Inspection (Service Code b
25)
Front Wheel Rotation Sensor Signal Abnormal (Service Code b 42)Electrical Wiring
Wiring Inspection
Visually inspect the wiring for signs of burning, fraying,
etc.
If any wiring is poor, replace the damaged wiring.
Pull each connector [A] apart and inspect it for corrosion,
dirt, and damage.
If the connector is corroded or dirty, clean it carefully. If it
is da ...
Front Wheel Rotation Sensor Signal Abnormal (Service Code b 42)
Measure the air gap between the front wheel rotation sensor
and sensor rotor.
Thickness Gauge [A]
Air Gap
Standard: 0.4 1.6 mm (0.02
0.06 in.)
If the measurement is not the standard, check each part
for deformation and looseness and correct accordingly.
If the measurement is t ...
For Secondary Fuel Injectors
Remove the fuel tank (see Fuel Tank Removal).
Disconnect the secondary fuel injector connector [A].
Connect a digitalmeter to the terminals in each secondary
fuel injector [A].
Measure the secondary fuel injector resistance.
Secondary Fuel Injector Resistance
Standard: Abo ...
