7) Install the circlip to the axle shaft, insert the shaft into
the differential assembly, and tap it into position with a
plastic hammer.
Thrust play:
Approx. 0.3—0.5 mm (0.012—0.020 in)
CAUTION:
If no play is felt, check whether the shaft is fully
inserted. If shaft insertion is correct, replace the axle
shaft.
Be sure to use a new circlip.

4. Overall Transmission
Page 1272 of 2248

When mounting a large power type radio, pay spe-
cial attention to the three items above mentioned.
Incorrect installation of the radio may affect the
operation of the ECM.
8) Before disconnecting the fuel hose, disconnect the fuel
pump connector and crank the engine for more than five
seconds to release pressure in the fuel system. If engine
starts during this operation, run it until it stops.
9) Problems in the electronic-controlled automatic trans-
mission may be caused by failure of the engine, the elec-
tronic control system, the transmission proper, or by a com-
bination of these. These three causes must be distin-
guished clearly when performing diagnostics.
10) Diagnostics should be conducted by rotating with
simple, easy operations and proceeding to complicated,
difficult operations. The most important thing in diagnostics
is to understand the customer’s complaint, and distinguish
between the three causes.
11) In AT vehicles, do not continue the stall for more than
five seconds at a time (from closed throttle, fully open
throttle to stall engine speed).
12) On ABS or ABS/TCS vehicle, when performing driving
test in jacked-up or lifted-up position, sometimes the warn-
ing light may be lit, but this is not a malfunction of the sys-
tem. The reason for this is the speed difference between
the front and rear wheels. After diagnosis of engine control
system, perform the ABS or ABS/TCS memory clearance
procedure of self-diagnosis system.
4-4b [T6C2] or [T9K0].>
C: PRE-INSPECTION
Before performing diagnostics, check the following items
which might affect engine problems:
1. POWER SUPPLY
1) Measure battery voltage and specific gravity of electro-
lyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
2) Check the condition of the main and other fuses, and
harnesses and connectors. Also check for proper ground-
ing.
OBD0091A
2. ENGINE GROUNDING
Make sure the engine grounding terminal is properly con-
nected to the engine.

6. INSPECTOR
Before advancing the vehicle after the engine starts, drive
the pump motor and valve for a very short time to function-
ally check the ABS/TCS brakes. It is not abnormal if, at this
time, operating noises of the valve and motor are produced
or kickback of the brake pedal is felt when stepping on the
pedal.
7. WHEN ATTACHING CHAINS
It is sometimes a good idea to turn off the TCS for better
advancing and accelerating the vehicle.
8. WHEN A DRUM TESTER IS USED (SPEEDOMETER
TEST, EXHAUST GAS TEST, BRAKE TEST, ETC.)
Before performing tests, turn the TCS off by operating the
TCS OFF switch or disconnect the fuse of ECM input
power source to put the machine out of operation. If oper-
ating other parts to put the TCS in the fail state
intentionally, trouble code will be recorded. Make sure to
clear the memory. Also, in a 2-wheel tester, wheel speed
sensor failure can be detected, making the TCS fail. This
case is also not abnormal and clearing the memory is
required.

2. VACUUM HOSE AND PIPE
Check vacuum hose and pipe (which connects actuator
and vacuum pump) for disconnection or cracks.
B6M0270A
3. ACTUATOR
1) Disconnect vacuum hose from actuator.
B6M0174
2) Connect vacuum pump as shown in figure.
3) Make sure that cruise control cable moves smoothly
and quickly when a vacuum pressure of 40.0 kPa (300
mmHg, 11.81 inHg) is applied to actuator.
Stroke: 35 mm (1.38 in)
4) When vacuum pressure is released from condition 3)
above, make sure the cable returns to its original position
smoothly and quickly.
5) After inspection, disconnect vacuum pump and connect
vacuum hose.
4. POWER SUPPLY
1) Measure battery voltage and specific gravity of electro-
lyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
2) Check the condition of the main and other fuses, and
harnesses and connectors. Also check for proper ground-
ing.
