1
1. Turn off the starter switch.
2. Disconnect the ECU connector from ECU.
3. Disconnect ADC control unit connector (C–41).
Is the continuity established between terminals (C–37) 1 and
(C–41) 4? After checking, connect the ADC control unit
connector.
Go to
Step 2
The harness is
broken. Repair
the circuit.
Go to
Step 6
2
1. Disconnect the battery ground cable.
Is there the continuity between the connector terminal (C–37) 1
and (C–38) 14?
The harness is
short-circuited to
VIGN. Repair the
circuit.

1. Disconnect the battery ground cable.
Is there the continuity between the connector terminal (C–37) 1
and (C–37) 12?
The harness is
short-circuited to
VB. Repair the
circuit.

Step 5
5
1. Turn off the starter switch.
2. Connect ECU connector.
3. Turn on the starter switch.
4. Set the transfer to the 2H mode.
Is the battery voltage observed between the connector (C–37)
terminals 1 and 25?
The phenomenon
is not
reproduced.
Refer to
“Trouble
intermittently
observed”,
or refer to
“Sec
4B1 Shift on the
Fly”.
The ECU has
failed. Replace
the ECU.
Go to

Phenomenon
Standard

33 (P1762)
The ADC line is short-circuited to
GND.
—
NOTE:
D
The on/off signal line of the shift on the fly system is
short–circuited to GND.
D
The system enters into the fail-safe mode because of
fusing or system protection.
(If a short–circuit is observed on GND, the output to
the on/off signal line becomes 0V.)
