DIAGNOSIS <TC-SST>

INTRODUCTION

M1225024900011

The TC-SST system can exhibit any of the following 
symptoms: noise or vibration is generated or fluid 
leaks.

The causes of these symptoms could come from: 
incorrect mounting, the fluid level may be low, or a 
component of the TC-SST may be faulty.

TROUBLESHOOTING STRATEGY

M1225007900018

Use these steps to plan your diagnostic strategy. If 
you follow them carefully, you will find most TC-SST 
malfunctions.
1. Gather as much information as possible about the 

complaint from the customer.

2. Verify that the condition described by the 

customer exists.

3. Check the vehicle for any TC-SST Diagnostic 

Trouble Codes (DTCs).

4. If you cannot verify the condition and there are no 

DTCs, the malfunction is intermittent. For 
information on how to cope with intermittent 
malfunctions, refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points − How 

to Cope with Intermittent Malfunction 

P.00-15

.

5. If you can verify the condition but there are no 

DTCs, or the system cannot communicate with 
scan tool, refer to the Symptom Chart 

P.22C-20

.

6. If there is a DTC, record the number of the code, 

then erase the code from memory using scan tool.

7. Reconfirm the symptom.
8. If a DTC is set again, go to the Inspection Chart 

for Diagnostic Trouble Codes.

9. If a DTC is not set again, the malfunction is 

intermittent. For information on how to cope with 
intermittent malfunctions, refer to GROUP 00, 
How to Use Troubleshooting/Inspection Service 
Points − How to Cope with Intermittent Malfunction 

P.00-15

.

10.Verify malfunction is eliminated. After repairs are 

completed, the complaint conditions to confirm 
the malfunction has been eliminated.

PRECAUTIONS FOR DIAGNOSIS

.

With the TC-SST assembly, the IG shutoff delay sys-
tem is adopted to improve the engine starting perfor-
mance.

When the ignition switch is turned OFF, the IG shut-
off delay system release the gear engagement in 
preparation for the next engine starting. This is a sys-
tem to delay the engine stop for approximately 1 sec-
ond, and the delay is not a malfunction.

.

If the gear is not in the reverse position, the R range indicator of 
the multi information display (a) and the R range indicator of 
the floor console panel (b) flash. This is a warning to the driver, 
and is not a malfunction.
In this case, return the shift lever to the N range, and move it to 
the R range again. If the flashing of each R range indicator 
changes to normal illumination, it indicates that the gear is in 
reverse position.

TC-SST TEACH-IN

M1225029400088

CAUTION

• Check the Diag. Version before Teach-in. If the Diag. Version is 0000, reprogram the ECU. (The 

software with Diag. Version 0000 does not have Teach-in function.)

• When the mechatronic assembly is replaced, reprogram the ECU and carry out the following 

Teach-In.

• When the clutch assembly is replaced, the following Teach-In must be carried out.

TEACH-IN ITEM

.

1. Teach-In operation type

There are two types of Teach-In operation and the type to be implemented varies depending on the replace-
ment part.

NOTE: When replacing the mechatronic assembly, execute in A 

→

 B order.

2. Scan tool item execution

To complete each Teach-In operation, multiple items must be executed using scan tool MB991958, and those 
items shall be executed in a designated order.
2-1. SCAN TOOL ITEM LIST

NOTE: 

.

•

Item No. 3 and No. 6 are displayed on the scan tool, however, those are not used.

•

Item No.8 is not displayed when the Diag. Version of TC-SST-ECU is pre-0002. (Diag. Version can be 
checked by the Teach-In screen of scan tool.)

2-2. ITEM EXECUTION ORDER

NOTE: Item No.8 is not displayed when the Diag. Version of TC-SST-ECU is pre-0002. (Diag. Version can be 
checked by the Teach-In screen of scan tool.)

.

3. Confirmation of Teach-In operation status

Using the data list simultaneously displayed with Teach-In, the execution status and results can be confirmed.

TEACH-IN PROCEDURE

NOTE: 

.

•

According to the transmission fluid state (fluid -filled state), Teach-In executed time is not equal.

•

Item No.8 is not displayed when the Diag. Version of TC-SST-ECU is pre-0002. (Diag. Version can be 
checked by the Teach-In screen of scan tool.)
