INSPECTION
1. INSPECT ECU-IG FUSE (Instrument panel J/B)
2. INSPECT PPS ECU CIRCUIT
(a) Disconnect the PPS ECU connector.
(b) Inspect the connector on wire harness side, as shown in
the illustration.

6 - Body groundIgnition switch ONContinuity
*5 - 6
Ignition switch ON.
Spin the rear wheel on one side with jacking or
lifting UP.
0 " 5 or more " 0
If the circuit is not as specified, check and replace the wire har-
ness.
*If the circuit is not as specified, inspect the speed sensor.
3. INSPECT PPS SOLENOID VALVE
(a) Disconnect the PPS solenoid connector.
(b) Measure the resistance between the terminals of the so-
lenoid 1 and 2.
Resistance: 6 - 11 W
If it is not as specified, replace the pressure control valve with
the solenoid valve.
(c) Check the PPS solenoid operation.
(1) Connect the battery positive terminal to the sole-
noid terminal 1.
(2) Connect the battery negative terminal to the sole-
noid terminal 2.
(3) Check that the solenoid makes a ºclicksº sound.
If it is faulty, replace the pressure control valve with the solenoid
valve.
NOTICE:

Do not apply voltage for more than 30 seconds to
avoid burning out the solenoid.

If repeating this step, wait until the solenoid cools
down enough that it can be touched by hand.
(d) Connect the PPS solenoid connector.
