4B2–92
Step Action Yes No
1 1. The car stops, the AT selector is the N position, and the brake
is applied.
When the TOD switch is changed to the TOD (or 2H) position, is
12V observed between terminals 44 and 47 (4L switch)?
Go to Step 2 Go to Step 3
2 1. The car stops, the AT selector is the N position, and the brake
is applied.
When the TOD switch is changed to the 4L position, is 0V
observed between terminals 44 and 47 (4L switch)?
Refer to “Trouble
intermittently
observed”.
Go to Step 3
3 1. The car stops, the AT selector is the N position, and the brake
is applied.
2. Select the TOD switch to the TOD (or 2H) position.
Is there the continuity between the connector (C–37) terminal 22
and 25?
Go to Step 5 Go to Step 4
4 1. Connect the ECU connector (C–37) and turn on the starter
switch.
2. The car stops, the AT selector is the N position, and the brake
is applied.
3. Select the TOD switch to the 4L position.
4. Turn off the starter switch and disconnect the ECU connector
(C–37).
Is there the continuity between the connector (C–37) terminal 22
and 25?
The ECU has
failed.Replace
the ECU.
Go to Step 9
Go to Step 5
5 1. Connect the ECU connector (C–37) and turn on the starter
switch.
2. The car stops, the AT selector is the N position, and the brake
is applied.
3. Select the TOD switch to the TOD (or 2H) position.
4. Turn off the starter switch and disconnect the connector (H–7).
Is there the continuity between the connector terminal (H–7) 5 and
(C–37) 25?
Go to Step 7 Go to Step 6
6 1. Connect the connector (H–7) and turn on the starter switch.
2. The car stops, the AT selector is the N position, and the brake
is applied.
3. Select the TOD switch to the 4L position.
4. After the transfer has changed to the 4L mode, turn off the
starter switch and disconnect the connector (H–7).
Is there the continuity between the connector terminal (H–7) 5 and
(C–37) 25?
Go to Step 7
GND is
short-circuited
between
terminals (C–37)
2 and (H–7) 5.
Repair the circuit.

7 1. Connect the connector (H–7) and turn on the starter switch.
2. The car stops, the AT selector is the N position, and the brake
is applied.
3. Select the TOD switch to the TOD (or 2H) position.
4. After the transfer has changed to the TOD (or 2H) mode, turn
off the starter switch and disconnect the connector (A–1).
Is there the continuity between the connector terminal (A–1) 12
and GND?
Repair the
transfer.
