CODE NO. P1565:
ACC Target Torque <ACC (4N1)>
caution |
If diagnosis code NO. P1565 is set in the engine-ECU,
surely perform CAN bus line diagnosis.
|
caution |
Replace ECU after certainly confirming that the communication
circuits are normal.

DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when the abnormality below is detected:
- The ACC target engine torque value, which the ASC-ECU
sends, is abnormal.
- More than 2 seconds have passed since the ignition switch was turned to "ON" position.
PROBABLE CAUSES
- Failed harness and connector
- Failed ASC-ECU
- Failed engine-ECU
|
STEP 1. M.U.T.-III CAN bus diagnosis
|
|
- Use M.U.T.-III to perform CAN bus line diagnosis.
|
|
Q.
Is the check result normal?
|
|
Go to Step 2.
|
|
|
|
Repair CAN bus line (Refer to GROUP 54C - Troubleshooting - CAN
Bus Diagnostics Table ). After repairing CAN bus line,
go to Step 5.
|
|
|
|
STEP 2. M.U.T.-III diagnosis code
|
|
- Confirm whether the diagnosis code is set in the ASC-ECU.
|
|
Q.
Is diagnosis code set?
|
|
Perform troubleshooting of the active stability control (ASC) system (Refer to
GROUP 35C - Troubleshooting - Diagnosis Code Chart ).
|
|
|
|
Go to Step 3.
|
|
|
|
STEP 3. Check the diesel fuel system diagnosis code.
|
|
Using M.U.T.-III, perform diesel fuel system diagnosis code (Refer to GROUP 13D - Troubleshooting,
Diagnosis Function ).
|
|
Q.
Is any diagnosis code set?
|
|
Repair the diesel fuel system (Refer to GROUP 13D - Troubleshooting,
Inspection Chart for Diagnosis Code ). Then go to Step
5.
|
|
|
|
Go to Step 4.
|
|
|
|
STEP 4. Read the diagnosis code.
|
|
(1)Use the M.U.T.-III, erase the diagnosis code of the cruise control system.
|
|
(2)Turn the ignition switch to the "ON" position, and press the ACC ON/OFF
switch to turn the cruise control system to ON (the cruise control display screen is turned
on).
|
|
(3)After turning the cruise control system to ON, when 2 minutes or more has elapsed
without operating the cruise control switches, read the diagnosis code of the cruise control
system.
|
|
Q.
Is diagnosis code No. P1565 set?
|
|
Replace the engine-ECU (Refer to GROUP 13D - Engine-ECU ).
Then go to Step 5.
|
|
|
|
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 Malfunction).
|
|
|
|
STEP 5. Read the diagnosis code.
|
|
(1)Use the M.U.T.-III, erase the diagnosis code of the cruise control system.
|
|
(2)Turn the ignition switch to the "ON" position, and press the ACC ON/OFF
switch to turn the cruise control system to ON (the cruise control display screen is turned
on).
|
|
(3)After turning the cruise control system to ON, when 2 minutes or more has elapsed
without operating the cruise control switches, read the diagnosis code of the cruise control
system.
|
|
Q.
Is diagnosis code No. P1565 set?
|
|
Return to Step 1.
|
|
|
|
This procedure is complete.
