NOTE: Operation of radiator and condenser fans is controlled by
vehicle Powertrain Control Module (PCM). Based on vehicle
speed, coolant temperature and A/C operation request, PCM
will command low, medium or high speed fan operation.

1) If neither the radiator fan nor the condenser fan operate,
check fusible link No. 5 (40-amp). See WIRING DIAGRAMS. If only the
condenser fan does not operate, check dedicated fuse No. 8 (20-amp).
2) If the condenser fan operates in all speeds except low and
A/C compressor clutch does not enter the ON state, check for A/C
compressor lock controller unit output signal. If the A/C compressor
clutch does enter the ON state, check condenser fan low speed relay
operation.
3) If the radiator fan and the condenser fan operate in all
speeds except high, check PCM. See appropriate G - TESTS W/CODES
article in ENGINE PERFORMANCE. If fan operation is not as specified,
check wiring harness for opens or shorts. Repair as necessary.

4) To confirm radiator fan or condenser fan operation, see
appropriate FAN OPERATING MODE (3000GT) table. If fan operation is not\
as specified, check wiring harness for opens or shorts. Repair as

DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Cruise control system is electronically and vacuum
controlled. System components include a control unit, actuator, vacuum
pump, cruise control switch, clutch pedal position switch (M/T),
cruise indicator light, diode, Park/Neutral (P/N) switch (A/T),
stoplight switch, vehicle speed sensor and A/T control unit (if
equipped).
System has self-diagnostic capability. When self-diagnostic
mode is activated, each switch and sensor is checked for defects. When
cruise control system has been canceled without using a normal cancel
method, a trouble code will be set and stored in control unit. Trouble
codes can be retrieved to help determine which circuit is
malfunctioning.

ADJUSTMENTS
CRUISE CONTROL CABLE
Remove link protector. Loosen lock nut. Hold link "A" so that
it touches link "B". Adjust free play by turning adjusting nut until
free play is.04-.08" (1-2 mm). Tighten lock nut. See Fig. 1 or 2.
Page 379 of 1501
as matched set. Side gears and pinion gears must be replaced as
matched set.
Reassembly & Adjustment
1) Install thrust spacers, side gears, pinion washers and
pinion gears in differential case. DO NOT install thrust block (if
equipped) at this time.
2) Install pinion shaft without lock pin. Check pinion and
side gear backlash. Install wooden wedge to lock side gears. See
Fig. 8 . Using dial indicator, measure gear backlash. Backlash should
be .0004-.0030" (.010-.080 mm). Service limit is .008" (.20 mm).
3) Adjust backlash by using different side gear spacers.
Ensure both sides are equally shimmed. Install thrust block (if
equipped) once correct backlash is obtained. Install pinion shaft lock
pin from ring gear side of carrier housing. Securely stake pin in 2
places. Ensure adhesive is removed from ring gear mounting bolts and
gear mounting surface. Clean internal threads with tap.
4) Ensure alignment marks on differential case and ring gear
align. Apply Loctite 271 to bolts, and install ring gear on
differential case. Tighten bolts in diagonal sequence to
specification. See TORQUE SPECIFICATIONS . Using appropriate adapter,
press on carrier side bearings.
DIFFERENTIAL ASSEMBLY (LIMITED SLIP)
NOTE: Manufacturer does not provide disassembly or reassembly
procedures for locking type differential. Use illustrations
for exploded views of assembly. See Figs. 11 and 12.
NOTE: See PRE-DISASSEMBLY INSPECTION under
DIFFERENTIAL ASSEMBLY (CONVENTIONAL) before disassembling
carrier assembly. For carrier assembly and drive pinion
removal, see DIFFERENTIAL ASSEMBLY (CONVENTIONAL) .
Disassembly
1) Once ring gear is removed, loosen carrier housing screws
in diagonal pattern. Separate cases and remove components. See Fig. 10
. Maintain parts in order of disassembly. Clean all parts in new
solvent.
2) Inspect condition of friction and spring plates and
friction discs. Replace disc and/or plates if worn or heat damaged.
Distortion of discs will cause incorrect clutch pressure. Scratches,
nicks or burrs on components can be repaired with an oil stone.
3) Discs must be flat and free of distortion. Check discs on
surface plate with dial indicator. Maximum warpage of friction plate
or disc is .003" (.08 mm). Inspect thickness of discs and plates.
Thickness limit between discs and plates is .004" (.10 mm).

Reassembly
1) Arrange friction plates and discs of each side of
differential. Measure each assembly thickness. Assembled discs and
plates should not exceed a difference of .002" (.05 mm). Replace discs\
or plates as needed.
2) Assemble one spring plate and one spring disc on each
side. Measure assembly thickness. Assemble disc and plates to obtain
minimum difference in thickness between each assembly.
3) Assemble clutch assemblies, pressure rings, pinion gears,
side gears and pinion shaft. Measure overall width of assembly plus
spring plates and spring discs (dimension "C"). See Fig. 13.
4) Determine depth of differential case (dimension "D"). On
2.4L, dimension "D" = "E" + "F" - "G"; on 3.0L, dimension "D" = "E" +
"H"
See Fig. 14. Subtract "C" from "D" to determine spring plate-
to-case clearance. Adjust spring disc thickness to obtain proper
spring plate-to-case clearance. Correct clearance is .0024-.0079" (.
060-.200 mm).

5) Remove spring plates, spring discs, friction plates and
friction disc from pressure rings. Mark components for location.

(.05-.20 mm). If clearance is not within specification, change thrust
washer to obtain correct clearance.
10) Apply gear oil and friction modifier to all components.
Install components in differential case. Ensure assembly order and
direction of clutch components are correct. See Fig. 16.

11) Install differential case cover with reference marks
aligned. Tighten screws to specification in several steps. See
TORQUE SPECIFICATIONS . Ensure cases contact each other completely when
fully assembled. Check for incorrect clutch assembly if gap exists.
12) Using Clutch Plate Preload Tool (MB990988), Shaft
(MB990989) and torque wrench, measure starting torque. See Fig. 17.
Rotate unit slightly before measuring starting torque.

13) Ensure starting torque is within specification. See
STARTING TORQUE table. Ensure adhesive is removed from ring gear
mounting bolts and gear mounting surface. Clean internal threads with
tap.
14) Ensure alignment marks on differential case and ring gear
align. Apply Loctite 271 to bolts, and install ring gear on
differential case. Tighten bolts in diagonal sequence to
specification. See TORQUE SPECIFICATIONS .
