CONSULT-II Function (A/T)NCS001BR
CONSULT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
CONSULT-II REFERENCE VALUE
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man- ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Display of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed upon completion of shifting (which is computed by TCM).

TRANSMISSION ASSEMBLY
Revision: 2006 December 2006 FX35/FX45
INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing A/T assembly to the engine assembly, attach the
fixing bolts in accordance with the following standard.

Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts with the specified torque. Refer to AT- 2 6 6 ,
"COMPONENTS" .
CAUTION:

Do not reuse O-ring and copper washers.

When turning crankshaft, turn it clockwise as viewed from
the front of the engine.

When tightening the tightening bolts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts. Refer to EM-72, "
INSTALLATION" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
transmission rotates freely without binding.

Install crankshaft position sensor (POS). Refer to EM-30, "Removal and Installation (2WD Models)" .

After completing installation, check A/T fluid leakage, A/T fluid level, and the A/T positions of A/T. Refer to
AT- 1 3 , "
Checking A/T Fluid" , AT- 2 3 1 , "Checking of A/T Position" .

INSPECTION
Installation and Inspection of Torque Converter

After inserting a torque converter to a A/T, be sure to check dis-
tance “A” to ensure it is within the reference value limit.
INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing A/T assembly to the engine assembly, attach the fixing bolts in accordance with the follow-
ing standard.

BODY REPAIR
Revision: 2006 December 2006 FX35/FX45
Read the Following Precautions When Repairing HSS:
1. Additional points to consider

The repair of reinforcements (such as side members) by heat-
ing is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550 °C (1,022 °F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appro-
priate.)

When straightening body panels, use caution in pulling any
HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.

When cutting HSS panels, avoid gas (torch) cutting if possi-
ble. Instead, use a saw to avoid weakening surrounding areas
due to heat. If gas (torch) cutting is unavoidable, allow a mini-
mum margin of 50 mm (1.97in).

When welding HSS panels, use spot welding whenever possi-
ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.

ACTUATOR AND ELECTRIC UNIT (ASSEMBLY)PFP:47660
Removal and InstallationNFS000O6
REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove LH side fender protector. Refer to EI-24, "
FENDER PROTECTOR" .
4. Remove ABS actuator and electric unit (control unit) mounting nuts.
5. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).

If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) can not be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.

Before servicing, disconnect battery cables.

To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten to
the specified torque.

Do not apply excessive impact to actuator, such as dropping it.

Do not remove and install ABS actuator and electric unit (control unit) by holding harness.
