.

YES <diagnosis code 28 is set> : 

Refer to 

diagnosis code 28: Inhibitor switch system 

P.23A-61

.

NO : 

Go to Step 2.

STEP 2. Transmission control cable check

Check the transmission control cable and inhibitor 
switch for installation condition.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Adjust the positions of the transmission

STEP 3. Engine system check

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the engine system.

STEP 4. Engine-A/T-ECU replacement
(1) Replace the engine-A/T-ECU.
(2) Test drive the vehicle.
(3) Verify that the condition described by the 

customer exists.

Q: Does a malfunction take place again?

YES : 

Go to Step 5.

NO : 

The inspection is complete.

STEP 5. Torque converter check

Check for damaged drive plate, incorrect installation 
in the input shaft (inserted at an angle) or damaged 
splines.

Q: Is the check result normal?

YES : 

Check the oil pump for incorrect installation, 

damage and etc., and replace the oil pump 
assembly if necessary (The oil pump cannot 
be disassembled).

NO : 

If repair is possible, repair the damaged
