3. Connect the scan tool, start the engine, and wait until the
compressor stops (the high-pressure switch is OFF).
4. Input simulated vehicle-speed signals km/h (2 mph) or
higher].
5. With the simulated vehicle-speed signals still being input.
conduct actuator test No. 09 (left turn) or No. (right
turn) so as to increase the pressure within the
pressure tank chamber.
During the actuator test, monitor the pressure gauge
indication and check whether or not the pressure when
the return pump activation starts (i.e., the maximum
gauge reading) and the pressure when the return pump
stops are both within the standard value.
Standard value:
Return pump actuation pressure
(14-26 psi)
Return pump cut-off pressure
50 (7 psi) or lower
7. If the internal pressure of the low-pressure tank is not
within the standard values when the return pump opera-
tion is actuated (i.e., the low-pressure switch is OFF) or
when the operation of the return pump is stopped
pressure switch ON), remove the reserve tank assembly
and replace the low-pressure switch.
G-SENSOR OUTPUT VOLTAGE CHECK
1. Unload the vehicle and move it to a horizontal surface.
2. Connect the special tool (scan tool) and start the engine.
3. Check whether the G-sensor output voltage is within the
standard value range when the vehicle-height is the
NORMAL vehicle-height.
Standard value:
4. If the G-sensor output voltage is not within the standard
value range, check the installation condition of the
sensor; if there is bolt loose, deformation of the body,
etc., repair it. If the problem is not repairable, replace the
sensor.
NOTE
If the G-sensor installation surface is at an angle (tilted)
due to body deformation or some other cause, a washer(s)
or shim(s) may be used to make an adjustment so that the
output voltage is within the standard value range.
