DRIVE LINE CONTROL SYSTEM (TOD)
4B2–62
Step Action Yes No
1 1. Turn on the starter switch.
When the motor is not moving, is the voltage between the
terminals 35 and 47 8.0 ∼ 14.5V?
Go to Step 2 Go to Step 3
2 When the motor is not moving, is the voltage between the terminal
48 and 47 8.0 ∼ 14.5V?
Go to Step 5 Go to Step 3
3 1. Turn off the starter switch.
2. Disconnect the ECU connector (C–37) and transfer connector
(A–2).
Is there the continuity between the connector terminal (C–37) 13
and (A–2) 7?
Go to Step 4
Repair the circuit.
Go to Step 11
4 Is there the continuity between the connector terminal (C–37) 26
and (A–2) 4?
Go to Step 5
Repair the circuit
Go to Step 11
5 1. Connect the ECU connector (C–37) and transfer connector
(A–2).
2. Turn on the starter switch
Is the transfer shifted to the low range from the high range?
Go to Step 6 Go to Step 7
6 1. Is the transfer shifted to the high range from the low range. The phenomenon
is not
reproduced.
Refer to “Trouble
intermittently
observed”.
Go to Step 8
7 1. After the starter switch is turned off, turn on the starter switch.
2. Right after the TOD switch is changed to the 4L position from
the TOD position, measure the voltage for 5 seconds.
Is the voltage between terminal 48 and 47 0V while the motor is
moving and 8.0 ∼ 14.5V after the motor moving stops?
Go to Step 9
Replace the
ECU.
Go to Step 11
8 1. After the starter switch is turned off, turn on the starter switch.
2. Right after the TOD switch is changed to the TOD position
from 4L position, measure the voltage for 5 seconds.
Is the voltage between terminals 35 and 47 0V while motor is
moving and 8.0 ∼14.5V after the motor moving stops?
Go to Step 9
Replace the
ECU.
Go to Step 11
9 1. Remove the motor asm with the connector (A–2) from the
transfer.
2. Connect the ECU connector (C–37).
3. Turn on the starter switch.
When the TOD switch is changed to the 4L position from the TOD
position, does the shaft in the motor asm rotate to the Low
direction?
Go to Step 10
Replace the
high-low motor
asm.
Go to
Step 11
10 When the TOD switch is changed to the TOD position from the 4L
position, does the shaft in the motor asm rotate to the High
direction?
Repair the
transfer asm.
Go to
Step 11
Replace the
high–low motor
asm.
Go to Step 11
11 1. Check that all the parts are mounted.
2. Clear the trouble code.
Is this step complete?
Verify the repair Return to Step 11
NOTE:
B Confirm the operation conditions when changing high
and low range.
– The car stops. (less than 2 km/h or 1.2 mph and
engine speed less than 1500 rpm)
– The AT selector position is neutral.
– The brake is applied (brake switch: ON)
B Verify the completion of changing the high/low range
by the TOD indicator on the instrument panel.
