 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

 Repair the CAN bus line. Refer to GROUP 54D, Can bus

Diagnostics Table P.54D-10. Then go to Step 2.

STEP 2. Recheck for diagnostic trouble code.
Check again if the DTC is set.

(1)

Erase the DTC.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if DTC is set.

(4)

CIRCUIT OPERATION

｠

Battery  voltage  is  applied  to  the  diagnosis
connector (terminal No. 16).

｠

The diagnosis connector (terminal No. 4 and No. 5)
is grounded to the vehicle body.

COMMENT

｠

When  the  communication  between  M.U.T.-III  and
ECM  is  impossible,  it  can  be  suspected  that  the
CAN bus line, power supply circuit of the diagnosis
connector, and/or grounding circuit are defective.

｠

Communication  can  not  be  achieved  either,  if  a
wrong vehicle type is selected on M.U.T.-III.
