DTC 15 (DTC C1015) ± G SENSOR CIRCUIT (FOR 4WD MODEL ONLY)
DESCRIPTION
While a vehicle is at stop or running, if the potential difference between the sensor signal terminal ªA14º and the
sensor ground terminal ªA4º is not within the specified voltage value, or if the signal voltage while at a stop does
not vary from that while running, this DTC is set.
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the DTC
and check again.

5) Disconnect connector from sensor.
CAUTION:

Do not separate sensor and bracket. It will lead to erro-
neous assembly.

Sensor must not be dropped or shocked. It will affect its
original performance.
INSPECTION
1) Check sensor bracket for bend.
2) Connect positive cable of 12 volt battery to ªAº terminal of sensor
and ground cable to ªCº terminal. Then using voltmeter, check
voltage between ªBº terminal and ªCº terminal.
When placed horizontally: 2 ± 3 V
When placed upright with arrow upward: 3 ± 4 V
When placed upright with arrow downward: 1 ± 2 V
If measured voltage is not as specified, replace sensor with
bracket.
INSTALLATION
1) Connect connector to sensor securely.
2) Install sensor with bracket and parking lever assy onto floor so
that arrow mark directs vehicle forward.

4) Turn ON ignition switch, shift transfer shift control lever to 4WD
position and check that indicator lights. Turn OFF switch after
checking.
NOTE:

When removing and reinstalling switch, use care not to let
dust enter transfer box inside.

Make sure to reset clamp for wiring which is located
where invisible directly.

It is recommended to work on transfer shift control lever
boot No. 1 from underside of vehicle on lift.

Identify this switch by its leg part which is different for that
of back up light switch.

4) When back up light switch has been replaced, check switch for
proper function with ignition switch turned ON and gear shifted
to reverse position. Turn OFF switch after checking its function.
INSPECTION OF 4WD SWITCH AND BACK UP LIGHT
SWITCH
1) Undo clamp and disconnect coupler of back up light switch
and / or 4WD switch.
2) Function of back up light switch can be checked as shown in fig-
ure.
There should be conduction at these terminals only when shift
lever is shifted to reverse position.
3) Function of transfer 4WD switch can be checked in the same
manner as back up light switch.
There should be conduction at these terminals when shift lever
is shifted to 4H, and 4L positions.
Upon completion of check, connect coupler and clamp wiring har-
ness as they were.
NOTE:
When replacing switch(es), use care not to let dust enter trans-
mission through switch hole(s).

ON LIFT
1) Drain oil from transmission and transfer.
2) Give match marks on joint flange and propeller shaft as shown
in figure. (front and rear)
3) Remove flange bolts of rear propeller shaft universal joint and
pull out propeller shaft.
4) Remove flange bolts of front propeller shaft universal joint and

5) Remove clutch operating cylinder from transmission. It is not
necessary to disconnect clutch hose from operating cylinder.
NOTE:

It is not necessary to drain transmission oil when dis-
mounting transmission and transfer for clutch mainte-
nance only.

Work without draining transfer oil is possible if front pro-
peller shaft is dismounted together with transmission and
transfer.
6) Remove clutch housing lower plate.
7) Disconnect couplers from 4WD switch, back up light switch and
speed sensor assembly and release their harness from clamps.
Remove nuts from joint with engine.
8) Apply transmission jack and remove engine rear mounting
member taking off its bolts.
9) After removing mounting member, move rearward transmission
and transfer assemblies placed on jack and then lower them.
