Step

Action

Yes

No

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.

Go to 

Step 6

Go to 

Step 3

3

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.

Go to 

Step 6

Go to 

Step 4

4

Is the resistance between the connector terminal (C–37) 1 and
(C–37) 25 less than 1

W

?

The harness is

short-circuited to
GND. Repair the

circuit.

Go to 

Step 6

Go to 

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 

Step 6

6

1. Check that all the parts are mounted.
2. Clear the trouble code.

Is this step complete?

Verify the repair.

Trouble code

Phenomenon

Standard

12

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.)
