DIAGNOSIS

STEP 1. Check the ABS/ASC-ECU.
Check if a failure related to ABS/ASC-ECU occurs.
Q: Is the check result satisfactory?

YES : Go to Step 2.
NO : Repair or replace the failure section.

STEP 2. Check the ABS/ASC-ECU connector pin terminal
and the connection status.
Q: Is the check result normal?

YES : Go to Step 3.
NO : Repair or replace the failure section.

STEP 3. Erase the DTC code, and drive the vehicle for a
while.
Check that the normal code is displayed.
Q: Is the check result normal?

YES : The procedure is complete.
NO : Return to START.

Code No. P1796: Idle neutral control malfunction

DIAGNOSTIC TROUBLE CODE SET CONDITIONS

• With the idle neutral control, the status that the

"actual slip speed

− target slip speed" is faster

than 300 r/min continues for 10 seconds.

• 1.05 seconds after the TCM activation, the failure

signal of longitudinal G-sensor is received.

.

PROBABLE CAUSES

• Malfunction of the CAN circuit

• Malfunction of the P0753: low clutch linear sole-

noid valve system

• Malfunction of the P0731: 1st gear incorrect ratio

• Malfunction of the TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics.
Use scan tool to perform the CAN bus diagnosis.
Q: Is the check result normal?

YES : Go to Step 2.
NO : Repair the CAN bus line (Refer to GROUP 54C

−

Troubleshooting

P.54C-17

).

STEP 2. Check the diagnostic trouble code.
Check the ASC diagnostic trouble code. (Refer to GROUP 35C
− Troubleshooting

P.35C-18

).

Q: Is the diagnostic trouble code set?

YES : Check and repair the relevant diagnostic trouble code

system.

NO : Go to Step 3.

STEP 3. Perform the troubleshooting for diagnostic trouble
code No. P0753: low clutch linear solenoid valve and
diagnostic trouble code No. P0731: 1st gear incorrect ratio.
Check whether the diagnostic trouble code is reset.
Q: Is diagnostic trouble code No.P1796 set?

YES : Replace the TCM.
NO : This diagnosis is complete.
