When the paddle shift UP switch being ON consecu-
tively for 60 seconds is detected. 

.

PROBABLE CAUSES

• Malfunction of paddle shift switch

• Damaged wiring harness and connectors

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 54: Paddle switch (up)

OK: The service data changes in response to the pad-
dle shift operation.

Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Go to Step 2.

STEP 2. Check the following connector:

• C-38 TCM connector

• C-208 paddle shift switch connector

• C-34 intermediate connector

Check the terminals for a contact status problem and internal 
short circuit.
Q: Is the check result normal?

YES : Go to Step 3.
NO :  Repair the damaged connector.

STEP 3. Paddle shift switch single unit check
Refer to 

P.23A-148

.

Q: Is the check result normal?

YES : Go to Step 4.
NO :  Replace the paddle shift switch.

STEP 4. Check for short to ground in the wiring harness 
between the TCM connector and the paddle shift switch 
connector
Between C-38 TCM connector (terminal No.22) and C-208 
paddle shift switch connector (terminal No.1)
Q: Is the check result normal?

YES : Go to Step 5.
NO :  Repair the wiring harness.

STEP 5. Symptom recheck after erasing diagnosis code
Q: Is the check result normal?

for 1 second. 

.

PROBABLE CAUSES

• Malfunction of selector lever assembly (Faulty 

shift switch assembly)

• Damaged wiring harness and connectors

• Malfunction of TCM

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list

• Item 52: Select switch (up)

• Item 53: Select switch (down)

(Refer to Data List Reference Table 

P.23A-127

.)

Q: Is the check result normal?

YES : Intermittent malfunction
NO :  Go to Step 2.

STEP 2. Check shift switch assembly
Refer to 

P.23A-154

.

Q: Is the check result normal?

YES : Go to Step 3.
NO :  Replace the selector lever assembly.

STEP 3. Check the following connector:
