1

1. Turn off the starter switch.
2. Disconnect the ECU connector from ECU.

Is the continuity established between terminals (B–49)11 and
(B–49)22?

Go to Step 2

Go to Step 4

2

1. Connect the ECU connector.
2. Start the engine.
3. Set the TOD mode.

Does the voltage between terminals 11 and 22 indicate at least
0.4V?

Go to Step 3

The ECU has

failed. Replace

the ECU.

Go to Step 5

3

Is the battery voltage always observed between terminals 11 and
22?

The harness is

short–circuited on

the battery.

Repair the circuit.

Go to Step 5

The phenomenon

is not

reproduced.

Refer to

“Troubles

intermittently

observed”.

Go to Step 4

4

1. Disconnect the M–27 connector.

Is the continuity established between transfer connector
terminals (M–27)8 and (M–27)7?

The harness is
broken. Repair

the circuit.

Go to Step 5

Replace the

transfer

electromagnetic

coil (solenoid

clutch).

Go to Step 5

5

1. Check that all the parts are mounted.
